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.

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.

The charger is model re7-59. It looks to be a specific type of plug for Panasonic only. You will likely have to order it directly fromPanasonic. 5.4 volt 1.2 amp output.

I don't know. I do know that most battery chargers are very specific to the batteries that they will charge. The battery chargers a and the batteries I have very specific milliamps and also voltage requirements. A 500 mA battery and a 700 mA battery are not the same. Likewise a 7.4 V and a 7.2 V batteries and chargers are not the same. So I think the best thing to do is to check with the Panasonic people to see what battery charger you should use and can use. Hope this helps good luck

I'm not sure - these batteries are 2550 mAh and the charger is bundled with 2100 mAh batteries. Good question to ask Panasonic. If have a bunch of the 2500 mAh and use the La Crosse Technology BC-700 Alpha Power Battery Charger. You can slow charge and it shows the charge level. I highly recommend this charger.

Absolutely. I regularly charge Eneloop and Energizer NiMh batteries with this charger. The key is the chemistry of the batteries. All nickel metal hydride batteries should work fine.

You should be able to charge these batteries, but get ready to learn you wasted money for crappy batteries... Most of the "high power" batteries I came across are fake and not holding more than half charge they promise. Only brand name batteries like Eneloop and Duracell were performed exactly as specified. Another problem with off brand batteries is self-discharge. I had several batteries losing up to 70% of charge within one month. On the bright side with this charger you will find-out what batteries you can trust. Good luck!

I have both kinds of chargers and use both but trust my better charger, not from enloop. I use a swiss charger with the read-outs and I know it will turn off charging when fully charged. I wanted an auto shut off when fully charged or it can hurt the life of the battery. I would invest in a better charger when you get a chance but it will do. Hope this helps.

Hi there, I'm just confirming what John said. I ordered this for a Panasonic ZS35 which, per Panasonic, uses the same battery (part #: DMW-BCM13). This charger and battery set has worked well for me. I do notice, however, that when these two batteries start to get low, the camera can misbehave a bit. For example, the lens won't zoom correctly, or the camera is slow to respond to changes in the settings. All of this resolves when a fully charged battery is installed. These batteries also may last for a tiny bit less time in the camera versus the OEM battery, but not enough to concern me. Hope this helps! Hi there, I'm just confirming what John said.

I'm using this with rechargeable batteries since around 5 months without any issues. The ones I'm using are from Eneloop (http://www.amazon.com/gp/product/B009LU9150/ref=oh_details_o09_s00_i00?ie=UTF8&ps;c=1), wonderful capacity; charger I'm using is also from Eneloop only (http://www.amazon.com/gp/product/B0058GZWXQ/ref=oh_details_o09_s00_i01?ie=UTF8&ps;c=1)

The problem is that most likely the phone charger is a dumb straight, non terminating charger that is completely overcharging the eneloops. I really am annoyed at Panasonic for doing something in their phones such that a completed charged set of eneloops will show up as need to be charged. Stupid. I want to charge my eneloops in my own smart charger, not the dumb phone cradle chargers.

Recommendations for eneloops and any rechargeable batteries. 1. Buy a good charger. 2. Don't quick charge, the extra heat will shorten the batteries life. 3. Replace them when they are low, don't leave them draining with the power on in devices. You will have two or three that won't charge without a paper clip jump (earlier post) . 4. Don't mix dead and charged batteries, the drained will be charged by the full ones the worst way to charge a battery.5. Dont mix newer generations of eneloops and older generations-it goes back to newer eneloops charging the older batteries. 6. Buy a good charger that monitors each battery throughout the charge!

Thanks for the lowdown. I didn't spend much money for the Eneloops, so as long as the work better than the Panasonic stock batteries, i'm happy for now. I will look into the batteries you mentioned though if I need to.

The same BQ-CC17 charger is bundled with both the 4th-gen eneloop (white) cells, and the 'eneloop Pro' (black) cells. The only difference is in the color: white charger goes with white cells, black charger goes with black cells.

The 300mA for AA and 150mA for AAA is what this individual cell charger utilizes to charge each cell, whether there is 1,2,3 or 4 batteries place into the charging bays. This is the recommended current by both Sanyo and Panasonic engineers to optimize the life span of the eneloop cells.

I have been using this charger on Eneloop batteries for the past year. I have stopped using the Eneloops on critical items because they have a low charge protect circuit built in each battery. They shut down abruptly with little warning instead of getting gradually weaker as they discharge. I still use them for music players and game toys.The MH-C800S charger works as advertised and I really appreciate it giving a charge status on each battery.
