Eneloop Panasonic BK-3HCCA8BA pro AA High Capacity Ni-MH Pre-Charged Rechargeable Batteries, 8-Battery Pack

To start off I wanna say that these batteries feel very robust. I feel like I can trust these more than some of the ones I’ve bought before.I know it looks don’t really matter when it comes to AA batteries but wow, these look awesome!These work well with the audio equipment that I’m using them for I use them for wireless gear mainly.They charging any AA charger just like a normal rechargeable battery would.They seem to last for a long time, even working after I forgot to charge him for the next session we used them for on a wireless mic.These provide higher power than normal rechargeable which is why they are perfect for audio equipment.

Right off the bat these batteries excelled in reaching their capacity in one shot, here are the stats for the cells (tested them in both the La Crosse and Maha C9000)Discharge 300mAh: Maha C9000Batt 5 - 872mAh / 3:12Batt 6 - 875mAh / 3:14Batt 7 - 875mAh / 3:13Batt 8 - 865mAh / 3:10Discharge - 250mAh: La Crosse BC-1000Batt 1 - 896mAh / 3:36Batt 2 - 904mAh / 3:38Batt 3 - 913mAh / 3:40Batt 4 - 907mAh / 3:39Both sets seem to do well, though the Maha seemed to be pushing the cells in the 1.1 volt range instead of the 1.2 range. I have yet to determine whether 300mA discharge was too much or they were not completely charged, though they should have been charged (see my review on the Maha charger for more details). I often hear people are not getting fully charged (or drained cells) and i wanted to clarify a few reasons why that might be. EIther you are using it in a device that does not work well with NiMH rechargeables or the cells are over a year old and may need a refresh before using.Which brings me to my next point, these cells were manufactured in January of 2014 and (well you can see when i wrote this) it's now 2015. So naturally i am guessing the reason the extra 50mA current pushed the cells voltage further down with the Maha charger (since the La Crosse was fixed at 250mA discharge from choosing 500mA as the charging rate on both chargers). So while these cells are precharged, they are generally only charged to about 70% and after being a year or so in storage they start to lose their vibrancy and often times a simple charge, discharge and recharge is in order. Certainly you can use these cells out of the package and they should work fine, however the older the cells are the less charge they will have in them during obtaining them.I am also glad to see that the package these cells came in was in good condition. There's been a few folks out there (including me) who has got Eneloops that has escaped out of the package either during shipping or they were shipped in that condition. It's not good for cells to be out of the package and can cause the batteries to short circuit depleting their life. There are other factors that could reduce the charge levels by environmental factors during the production to when they get to your home and with a few folks that have done tests, these batteries can be low as 40%. My particular cells seemed to be around 65% capacity. So even though these cells have been labeled as precharged, the capacity is not generally at 100% capacity and functioning 100% right from the package. These batteries do hold their charge for a long time and i wouldn't expect them to die at 3 years in storage. They may not have as much capacity as those HSD cells but often times you are sacrificing cycles for extra capacity.These cells (both AA/AAA's) offer the best of both worlds. I use these for emergencies when my regular Eneloops are discharged and i got no alkalines available. One thing i will note if you use these cells 3x out of the week (that's discharging and recharging) you can probably get 4-5 years out of them. You can get more cycles out of them if you recharge them at 1.26 volts instead of 1.20 volts. So if you use these in regular applications you may want to think about recharging them on a regular basis (depending on how much you use them) and for low drain devices, regular Eneloops would be a far better idea. I use my older cells for low drain devices so my newer regular Eneloops gets used in the high drain devices. But if you are light with these you should get 5+ years out of them. As i stated earlier, i prefer using regular Eneloops for daily usage as those cells will outlast these, but for high drain critical applications these cells (both the AA/AAA) are excellent.Also if you see rechargeable AA Duracells with the mAh capacity of 2400, those are similar (or the same) as the AA Eneloop Pros.

Battery is very long lasting and charges very quickly. Works well with high usage items such as RC remote controls and wireless microphone. Battery charge is able to maintain power for a whole month of use.

I really hate seeing when people buy a cinderblocks of disposable batteries while these exist, but I guess they need the extra voltage idk. But these batteries work perfectly in controllers and anything else that takes a AAA battery. The total lifespan depends on how you treat them but ive had mine for years without fail, just get a quality charger.I would highly recommend these, for the value and long life of rechargeability.

Great batteries for a camera flash unit. I need quick high power during photo shoots at school and for rechargeable batteries, these are quick to recharge the flash. I've been using these for over a year and it hasn't failed me. I do carry an extra set for those photo shoots but so far haven't needed to switch out for a day's session.Pros: rechargeable and quick power up when needed.Cons: seems to loose some charge while in storage. I do a refresh charge before using.These are a great buy and I love them. It does cost a bit more but it puts out the power when needed. Enjoy!

I like Eneloop Pro rechargeables. They have the largest capacity of any rechargeable battery and they seem to last long and don't fail prematurely like other brands. What I don't like is getting poorly packed or damaged packages from Amazon.

Many years ago I wanted to go rechargeable for all my in house devices. I started with the white and black Eneloops. The Eneloops I have back from 2015 still are working in 2022. I've bought more over the years of course too. The black ones can charge 500 or so times, the white ones over 2,000 times. Now, if you charged a battery once a week, it would take 10 years to charge around 500 times. The black ones do have a bit more 'fuel in the tank', and are better for devices like cameras; but overall, the white ones have seemed basically just as good to me for most uses. And they are like half the cost. And they can be charged 4x more. So, decide what you want / need.Both the black and white versions work great. I use the black ones in more 'high demand' devices (flashlights, portable fan, etc.), and the white ones in less demanding devices (like remotes, mice/keyboards, etc.).Haven't had a single issue. I use their 4 port charger (model BQ-CC17). I have two of them that I got with 4 packs of batteries. So, I can easily charge 8 batteries in a few hours. Very easy to keep all my batteries topped up. I have one bin for full batteries, and one for empty; and I just charge them whenever I have time.I haven't bought one time use batteries in about a decade, and I don't plan to ever again. If you are thinking of going rechargeable, these are a great way to start. You get quality that will last, which is the point of going rechargeable in the first place. I have tried many other brands as well, most had issues over time. The Eneloops just keep on going. I will say the Amazon brand batteries have also been great. All have kept working for years and they hold a good long charge and seem good quality as well.
