They also charge cells individually so you can remove or add another battery during charging. Are you new to rechargeable batteries? It will charge relatively fast and uses colored LED lights to show whether a battery is empty, still charging, fully charged, or damaged. This charger is not recommended to use with the Lite model or older batteries.
There is a video on Youtube in Japanese as well as in English that will demonstrate the ways this charger works. Please look at the Eneloop battery charger overview page for more information on all chargers made by Sanyo and Panasonic.
These chargers can refresh your batteries, and check the capacity! More about this in the Advanced section. I get this question asked a lot. Yes, you can charge Eneloops with your fill in brandname here NiMH battery charger.
It all depends on how much you care about it. If you are looking for a new charger, look for one that is made by Panasonic, or any advanced charger I listed on the website. Eneloop AA batteries are mostly charged till about 1. After the batteries are taken from the charger, the batteries will slowly drop in voltage.
So charging up to1. See the below picture from the Panasonic website. The somewhat horizontal line is under load and about 1. Do I need to charge my new Eneloop batteries before I start using them? No, that is not necessary. The package claims: Ready to use, and that is correct. This means you can use the Eneloop batteries right out of the package. Just keep in mind that Eneloops do not come from the factory fully charged. So only if you want to use their full capacity you should charge them before using them.
Should I discharge my Eneloops completely before charging them? No, that is unnecessary. You could even extend battery life by not discharging or fully charging the batteries each time. Just make sure you don't use a dumb charger. They will charge the batteries for x amount of hours. Check out the list with the best and worst Eneloop chargers.
How long does it take to recharge Eneloop batteries? It honestly depends on the type of charger you use. Check out the manual of your Eneloop charger to know how long it can take. And if you have an advanced charger , you can set the speed by yourself.
Give them a cup of water or even a lollypop will do. Joking aside, you can do a refresh with the built-in Refresh function on some Panasonic and Sanyo Eneloop chargers. And you could do a refresh on a more advanced charger by setting the mA. Want to know what a refresh means? Check out the explanation in the advanced section.
It is recommended to set a refresh at between mA for charging and discharge rate for regular white AA Eneloops. So better set the charge rate at max, in this case, mA. But don't go over mAh for AA Eneloops.
Can I refresh Eneloops if I don't have a charger with a refresh option? Just charge them up with the charger you have, and put them in an old-fashioned flashlight with an incandescent bulb, run it until they're completely dead, then charge them up again. List of all Eneloops produced between and today. This means the charge will take 1 hour to charge the battery.
If you see a. Another way to remember it is to say, 0. This is a charge termination method that detects a full battery when the Voltage of the battery drops within a certain time during the charge. Delta can be translated as a Change. So if the charger senses a change in voltage so that the Voltage drops which means negative within X amount of time it will notice the battery is fully charged. See this graph that HKJ made and look at the Red line. Just before it stops charging you can see it going down.
The problem with low C charge rates is that the Voltage drop is difficult to measure. Therefore it is better to use a. Also notice that the black line, temperature rises at the same time, they go hand in hand.
When a battery is depleted the Voltage is lower than when fully charged. Thanks in advance. Eneloop was originally developed by Sanyo. Panasonic aquired Sanyo and in that deal, the Japan factories were sold to Fujitsu….
XX is the first generation eneloop pro by Sanyo, while the Fujitsu eneloop pro is 2nd generation and made in Japan. All Panasonic eneloop are made in China and other countries but not Japan. I used mine for years to charge the eneloop. I just recently got a set of 4 AA Duracell. Could these just simply be the rewrapped overpriced Eneloop XX they were talking about? The tops are black. Back of the package says mAh. When you place an AA battery into one of these D-spacers do they equal the power of an alkaline D battery?
I have a rechargeable gaming mouse I use for work, and have been looking at other rechargeable AA batteries to replace the stock AA NiMH battery that came with it. They are not legit. Most of the UltraFire high mAh claims have been debunked as well as a lot of fake ones on eBay.
I guess the loop hole is taking all the batteries that come in the listing and wiring them in parallel. I will have to test on my new BT-C charger and update my blog once I get around to it. Ever hear about the exploding ecigs that use high discharge batteries?
Use the right battery for the application. Even reputable manufacturers like Samsung had to replace all those Note 7s recently. Also Amazon is asking for people who had purchased recalled scooters to pretty much get rid of them for a full refund. As for the gaming mouse. Spend the extra and get the eneloop pro. They are the best rechargeable batteries especially since they have set the bar on LSD low self-discharge. Bought a Quad pack of Ultra Fire and singles from the Netherlands through eBay, low static discharge for a Solar Storm dual Cree LED bike light, used daily with the 4 pack, which is the battery in a wrapped pack one unit , stay bright until the pack runs out of juice.
I Must have got lucky, they have been going strong with no noticeable degradation for about 1. When Ultra Fires are good they are really good and almost equival my Eneloops, though this may not prove true as they are not as time tested, So Far my Ultra Fires are an amazing 2nd best to any battery I have ever used. The small super bright fitting single batttery Cree LED Flashlights are indispensable and able to light up a foot square area from a 3rd story window like it was a headlight.
Does this mean that when I insert 4 batteries, I have to program -every- of these 4 slots separately? Yes — it is a bit tedious. I often make five or more button presses per battery, e. How can that be? It is very expensive to keep replacing them therefore I am looking for the best 9v rechargeables to power my wireless microphone. Do Eneloop do an equivalent? If not, what 9v would be best suited for wireless microphone use?
Have you seen the link on top of this article about 9 Volt rechargeables? Keep that chart from the article in mind for radio mics. Many radio mics use voltage to give an indication of remaining power. That can drop suddenly i. It is still doable if you are aware of this and know how long your healthy fully recharged rechargable will normally last in the mic rather than using the mics indicator.
I create illuminated sculptures and am looking for ways to be more environmentally friendly. Up until now, I have been using alkaline batteries.
The string LED lights I use attached to a battery box with a timer. I have been testing the eneloops on a battery box that takes three AA batteries.
The timer turns the lights on for 6 hours every day at the same time. With alkaline batteries I get about 3 weeks.
With the eneloops I got from Amazon I get one day at full power and the next day they come on bright and dull after about an hour. I agree — it sounds like something is wrong. The Eneloops should last at least as long as the alkalines. I uses Eneloops to power wireless mice and they last for months. Perhaps the Eneloop were damaged somehow — possibly during charging. What voltage do your lights need? That is most likely the issue here.
An alkaline cell produces 1. A NiMH cell only produces 1. You will probably get acceptable results with NiMH if you switch to using a 4-cell battery box and use the appropriate series resistor to limit the current through the LEDs. Unfortunately, you actually need both to have the FULL set of features for all occasions. The caveat is that revival is possible in many cases, but not if the battery is damaged internally, chemically or mechanically, by serious or complete over-discharge.
It also can auto run that cycle three times and show the last tested mAh rating of the battery. I have adopted the technique of doing two of the three cycle charges on all new batteries. By the end of that, they are unlikely to show any further increase in capacity. Make sure you get the current version if you are paying that full price. Older version should be discounted. Neither unit can currently handle the unique new dual voltage 1.
The mAH only gives you cycles but that works out to 1,AH of life. Yes for a bears trimmer they would be fine, I use them in my last a long time. You can recharge them. The ones in my trimmer I usually top off once a month. I trim once a week as well. This was a great read! Many thanks for sharing helpful information about AA rechargeable batteries. If someone could correct my thinking on this, I always had the perception that standard non chargeable AA batteries last longer than ANY rechargeable AA batteries.
I have always used standard Alkaline AA batteries for everything. Many years ago, I tried the Energizer rechargeable charger with there rechargeable batteries and it appeared I was changing batteries frequently and was not getting good life out of those batteries. I was finding myself charging batteries more so than using them. I understand that the device or product that you are using the batteries with, plays a factor in battery drainage.
New rechargeable batteries will last much longer then alkaline now a days. I suggest a good charger the panasonic one is fine. Avoid the duracell and energizer ones and any chargers that charge in pairs.
You want a charger that charges each battery slot independent. A good cheap one is the poweradd charger. I prefer the opus charger because I can run test and check the capacity of the batteries to see what useful life they have. And can refresh batteries that have sat for several months. Rechargeable batteries hold about x the energy of alkaline.
Lots of its power is wasted overcoming its internal resistance. In my high powered flashlight. Rechargeable batteries will provide turbo for slightly over a hour before needed recharging.
Turbo being lumens around 3 amp draw. Alkaline batteries last roughly 20 mins and completely done for. Alkaline batteries can not handle high drain devices. Flashes cameras and flashlights all recommend nihm rechargeable or lithium primaries and rate there abilities off them not alkalines. Alkaline also leak, how many times over the years have you opened a old flashlight, remote, kids toy to find the inside completely rusted out.
Usually leak when dead but not always. Very very very rare. I suggest getting the amazon pro batteries or the duracell rechargeable from Wal-Mart.
The black top ones. These are name brand eneloop pros just with a different wrapper. The author is wrong about the duracell batteries. Any nihm rechargeable made in Japan is made from the same plant.
Fdk produces them all for many companies. They own the technology not panasonic. They are the only plant in Japan that can produce nihm rechargeable batteries. Panasonic owns the eneloop name but not the technology. Eneloop made in China are not the same quality as made in Japan. They last only half as long as many independent test show.
Make sure you get batteries that are made in Japan. Only exception the imedion batteries. Amazon pro , duracell, fdk batteries all made in Japan. I buy a set every 2 years even though life is left. I keep on hand for emergency situations such as hurricanes etc. Even though I can recharge my batteries in a vehicle it might not be realistic. I was ground zero for Katrina with 40ft of water. Do not purchase from a store, order online. But lithium is much better then alkaline and easier on the environment.
That way I can have weeks worth of lighting if another storm comes and its 3 weeks without electricity again. I can power all my lanterns and flashlights and run fans. I had 30 of those batteries and on those alone I could have light for weeks. And recharge them with a cigarette lighter or my solar panel and my nihm. I know I went off topic a lot but there are many options out there. If batteries would last you years its cheaper route then rechargeable even if you go all rechargeable I still recommend some back ups.
Alkaline and lithium last decades so if nothing else you have time to slowly use them. And if you have kids to buy presents for batteries with the toys is always a nice addition.
Which ones are you referring to? Can I charge lithium rechargeable batteries in a norml battery charger or do I have to buy a charger especially for lithium batteries? Thank you. Sue, Lithium Ion batteries have a different voltage compared to NiMH rechargeables, and the charging algorithm is also different so yes, you will need to buy a specialist Li-Ion charger.
There are many available on amazon or Ebay with differing features and charge speeds but make sure you check some reviews before you buy. Chris also mentions that Eneloops made in China only last half as long as Eneloops made in Japan.
This is really not the case, and the spec for both types is the same. Can ytou advise me on alternatives if you dont make them in Eneloop? What do you recommend, including new radios. For example, you could check your avalanche before you leave the house and it would read full. By the time you get to the car, it could hit the cut-off voltage level and shut off. Not good in that situation.
Do I have to completely run out a rechargeable battery before I can charge it again, or can I charge it when I want? The charger will show a yellow light when charging and go off when completed. It mainly tells orders me to buy new cells. I cannot see why I should buy new cells simply because a charger tells me, and just will not start charging, while I know that the cells perform well again after that dumb charging. I suggest you also buy a dumb charger to be used beside these sophisticated ones that cannot do so.
Charge it whenever performance starts to degrade, or before if you want. Make sure you get a charger that treats batteries individually, not in pairs and that shuts off automatically. For digital cameras like my 10 year old Canon Powershot they have lasted well over their rated cycles. Much of it recording Bluegrass jams in low light. I usually do buy packs of 4 and run several cycles in an old fashioned flash light just breaking them in.
I swap in sets as needed, never dividing them. After cycles, I get a solid full charge in them and meter test again for matching up pairs. I then hashmark the batteries with permanent marker as set 1 or 2. They might get another test in 6 months or so as if they were new to verify all is well. The good batteries will all come up to 1.
The current set of 4 are vintage and still charge to 1. In such light duty, they last many moons and are not cycled much. I purchased the AA eneloop batteries 4 pack with a Panasonic Advanced charger.
They came from China , sold on eBay. There were two of the dark and light blue batteries. They never get a full charge, even though the charger indicates a full charge and they will not last through 2 pictures in my point and shoot camera. I am thinking since there are nothing but great reviews, that these batteries must be FAKE. You should not buy the low discharge Eneloops for solar lights. They recharge every night.
You are wrong on all counts. Every single one. It also has alkaline battery protection. Alkaline battery Protection — Automatically recognizes an Alkaline battery and Prevents Charger operation and damage. Short circuited Battery Protection. Globally certified for safety. Recharges your batteries correctly each and every time. No over charge, no under charge. Just the right charge each and every time.
Universal auto-ranging switching adapter assures Worldwide voltage compatibility. Made to last in rough environments, and uses a rugged DIN style connector. So — what are you talking about, please. I have AA chargers that are at least 10 years old.
They have settings for NIMH and …… batteries. Do I need to get a more up to date charger for the batteries you have currently recommended? Will the new batteries charge faster on a more modern charger? I recommend getting a good charger for your batteries.
A good quality charger will revive and recondition your batteries, and they will indicate if a battery is malfunctioning, which is quite useful. Yes, the newer NiMh batteries have a longer shelf life, and are generally more reliable than the older kinds. I see no reason to continuing using alkaline batteries. I recommend spending money on a good charger whenever possible.
The better chargers will recondition the batteries, and they allow you to weed out the problematic batteries easily. We see the batteries being sold with chargers but the chargers are not highly rated?
So we should use a non Panasonic charger for the top of the line Eneloop batteries? I tried quite a few battery brands until I found eneloop years ago. How do I put batteries in my Energizer charger? How do you tell if rechargeable batteries are charged? Do rechargeable batteries go bad if not used? Can Eneloop charger charge AAA batteries? What is the difference between eneloop and eneloop pro?
Why are eneloop batteries better? What do the lights mean on an Energizer battery charger? Are rechargeable battery worth it? How long does a rechargeable battery last?
Are Duracell and Energizer the same company? What type of rechargeable battery lasts the longest? Which AAA batteries last longest? What are the disadvantages of rechargeable batteries? What happens if you put a non rechargeable battery in a charger? What happens if you leave a battery charger on too long? This means you can use your batteries straight away if you wish, instead of waiting for them to charge up first.
You can use any NiMH battery charger with the Eneloop batteries. However, it is usually recommended to use a charger that is the same brand as the batteries.
Smart chargers are a great choice, as they have advanced features such as automatic cut-off when the batteries are fully charged. This can help to reduce any damage to the batteries. We offer a range of Panasonic Eneloop battery chargers that come with batteries included. The time it takes to recharge your Eneloop batteries can depend on the charger you are using.
It also depends on the capacity and size of the batteries and how many batteries you are charging at once.
