The eneloop (and other low-self-discharge cells) can be charged using any 'smart' charger, such as the Panasonic BQ-390.

As a general rule, all fast charger (meaning charge time less than 4 hours) has to be 'smart', while most slow chargers (charge time longer than 6 hours) are 'dumb'. This is because NiMH can be safely over-charged at lower rate (0.1C to 0.2C) without immediate danger, although the damage will build up over time. On the other hand, over-charging at higher rate such as 1C will lead to rapid heating, which can be dangerous. Therefore a fast charger must have circuits to monitor battery status, and stop charging when the end-of-charge signal is detected (negative dV/dt, delta-temperature rise, etc) As a general rule, all fast charger (meaning charge time less than 4 hours) has to be 'smart', while most slow chargers (charge time longer than 6 hours) are 'dumb'.

NLee, I think Amazon should pay you for providing such great info on their site! :-) Thanks.

Yeah, I almost balked at the 'must charge in pairs' requirement when I made the buy a few weeks ago, but the price was right, and 2 out of my 3 uses for the batteries will be in pairs. The third device uses 3 AA, so I'll have to figure that one out. Thanks, again for the info!

I have an old VTech model ev2653.The original batteries supplied with the handsets were rated 1.2v, 600mAh and werethree individual AAA batteries.As I recall, the manual said to charge the batteries for a minimum of 12 hours prior to using the handsets.I'm wondering if the eneloop batteries would be able to be charged and used in thissystem.

High Flyer,I looked up the user manual for EV2653 cordless phone system. The manual says to charge the included 600mAh AAA cells for 12 hours prior to first use, but subsequent maintenance charge only takes 8 hours. Base on this info, I can safely conclude that it is a dumb charger with a constant current of 75mA.You should be able to use the eneloop 800mAh AAA cells in the handset just fine. However, since the handset is being charged daily, you don't really need low-self-discharge cells in it. Ordinary 1000mAh NiMH cells may actually do better since they can provide longer talk time for the women in the house... No wait, just stick to the eneloop cells in that case.

so when ever i need to charge my AA batteries i should use "Discharge/Refresh" mode? I just bought this charger & i do have the booklet but just want to make sure i am charging my batteries correctly every single time. I am using the eneloop AA.

teoretic yes but you never find a replacement on the market, my guess. I can't find the charger on the market, even at panasonic shops.

Hello Travis, yes you "can" charge your Eneloop on any nickle metal halide (NIMH) charger, including the Energizer one, but be aware that the Warranty on the Eneloop is only valid if charged with an Eneloop/Sanyo charger. For $20, you can buy the basic Sanyo/Eneloop charger that charges only in pairs, for less than $30 you can buy the Eneloop charger that charges 4 batteries individually( and also has two bays that will "quick charge " in 1 hour). Since the 3rd generation Eneloops can be charged 1800 times, I bought the best Eneloop charger and love it. Right now Costco has a $20 package with 12 batteries, the basic eneloop charger and a few spacers to boot. My answer comes to you after I reviewed the "Eneloop" frequently asked questions website. Hope this helps.

Yes, there is a Eneloop charger available. You may be able to charge these in most any rechargable battery charger, but I've never tried that.

I actually use an Energizer charger for my Eneloops. And, yes, it is a smart charger in that it stops charging when the battery is "full".And, as far as shelf life. My kids use them for their gaming controllers and swap the batt's in charger when it's time. I use them in my digital camera and don't have to worry about the battery being dead after sitting for month. I keep a new set in the bag just in case they do die on me. I also use them in my remote controls.I would not recommend their use in smoke detectors, clock radios, or anything that will put a continual and uninterrupted drain on them. Those are what alkaline batteries are for. I actually use an Energizer charger for my Eneloops.

According to Sanyo eneloop web site: "Eneloop batteries are not limited to Eneloop chargers or any special proprietory charging technology and can be charged using other quality non-Eneloop Nickel Metal Hydride (NiMH) battery chargers." As long as you have a good quality "smart" charger (meaning that it charges each cell individually and stops whenever each cell is full), you can charge the eneloop cells with it. Personally, I would avoid those 15-minute Super-Fast chargers.

Kinda late here, but with my experience Duracell provides the best though Eneloops have been known to work well in this device as well.This device won't work well on older NiMH batteries though, if the mA has been lost in the batteries this device won't charge very well.

I'm using a basic generic charger to recharge, Enloop, Duracell, Failsafe and Energizer batteries and never had a issue. I can't say whether a Duracell charger is going to definitely work, since I don't use one. If in doubt try charging a pair of Enloops and see what happens.

Sorry I'm not sure about the compatibility side! I never purchased the quick charger I just use the factory supplied cord for the hd disc video camera with battery still docked in camera and it only takes about 30mins or so and last a long time ill put it this way the small blu ray disc are able to burn 45mins hd and I do 2 of them with no problem! Ive had the batt 3yrs with no issues. I hope that I helped you and sorry for the late reply! Regards,Pete.e

Maha has a good charger/battery analyzer. It's designed to work with Eneloops. La Crosse also has some excellent ones or if you want simplicity go with the Eneloop charger supplied by Panasonic it comes with 4 batteries too.

I have some much older chargers (circa 2000) from Panasonic, and they still could do a pretty good job on charging all new and older NiMH. Those NiMH that refused to charge in the new charger (blinking) are getting charge fine from my old Panasonic charger. Although, the batteries capacity of holding the charges decreased as they aged. But squeezing more life out of these batteries to me considered more "green" than just toss them away and flush out my "green" bills.

eneloop 4-Position Ni-MH Rechargeable Battery Charger (white)Or another charger for NiMH batteries.

Hello I´am not sure about this specific Panasonic model and specifications. I would suggest FIRST to check on the previous charger voltage; if Panasonic´s and the above AC Adapter use the same voltage it shhhhhall work. For my Panasonic that I´ve bought in Germany it´s working just fine. I would buy it again if necessary. Hope this orientaion helps.

Do these Eneloop rechargeables have to be charged in an Eneloop charger? Or, will another HiMH charger work? Thank you.

This will work for your camera and I think you will be quite pleased with the performance and the quality of this battery and charger kit, especially for the price. I prefer this charger by the way over the Panasonic because when you plug the battery into the Panasonic the charger goes green and turns off when charged. With this charger its amber and goes green when charged. It just makes more since to me and this charger also charges in less time than the Panasonic. I can take well over 600 photos on one charge. Video clips will obviously drain the battery more quickly. Thanks for your question and I hope it helps with your decision.
