1x4 Panasonic Eneloop Rechargeable arrived in excellent time. They held a charge, but not a full one. I topped them off, and they presently hold a higher charge than any of my other rechargeables. As COSTCO is no longer carrying this brand, I guess this is the best price available. I've only had them for a week, so I have no idea how long they will hold a charge, or how well they will perform. I've used Eneloop rechargeables for about 5 years, and they far outperform any other brand, and work longer, as well!

As far as rechargable batteries go these are meant to be some of the best. I've been attempting to slowly transition away from single use batteries and go to rechargeable ones in all my devices and I've chosen these solely because I want the capacity that these have. Compared to other rechargeable batteries I have these have some heft to them and you can tell they're packed better which allows for the high capacities these give. In the devices I've tried these get about 4-5x the longevity of other rechargeable batteries I have and capacity seems to be holding strong through multiple charge cycles.

Best batteries you can get

Bought these as spares so I could keep a couple on the charger at all times. They're great batteries that last ages. Hands-down the best brand for rechargeable batteries (though I can't speak for the non-Eneloop Panasonic offerings)You can get higher-capacity Eneloops, which last longer between charges, but they degrade about four times as quickly, too. These regular Eneloops are a no-brainer if you want good-quality batteries that will last you years.

For cameras with high cutoff voltage or high current demand.

Manufacturing date printed on the blister. Water based electrolyte dries out, raising internal resistance and voltage drop under load. This is the reason of such importance of knowing the manufacturing date of secondary nickel cells. My Canon works with these or lithium primary cells only.

Great rechargeable batteries for home use.

Made by Santo, this is a quality product. They hold their charge like no other battery one used. Other rechargeable batteries online are often fakes or clones and misquote the milliampere ratings. Why risk that? I buy Eneloops in AA's & AAA's unclosed in mfrs packaging only. Started using 7 years ago and haven't thrown away any yet. Be sure to use the Santo ni-mh charger! You won't regret buying these.

Haven't bought new AA batteries in years, and these are why

From remote triggers, to speedlights, to LED lights of all kinds, to my ham radio gear - I've tried to build as much of my systems around Eneloops where I can, because they work so well. I've been using them for 7 years or so - always the white ones, no real need to go to the higher capacity versions - and I can't begin to calculate how much waste they've saved in batteries I haven't had to buy in that timeframe.I wish Panasonic would have more options for charging 8+ cells at once, but there are aftermarket options for that, or you can do what I do and just dedicate a wall-mounted power strip for Eneloop chargers.

MADE A RECHARGEABLE BATTERY MAN OUT OF ME

I love these rechargeable eneloop batteries so much, that I have purchased these batteries for all of my flash units. These batteries are powerful and they last a long time during my photo shoots to the point where I have never had to change them. The only regret I have about eneloop rechargeable batteries is that I should have purchased them years ago. Since buying and using these batteries (which is about 6 months now), I have never gone back to purchasing or using Duracell AA batteries and I never will go back using them for my flash equipment.

Recommendeed product

I bought these to supplement some batteries which I already own. These "1900" variants are better for people who regularly use rechargeable batteries, they provide or tolerate many more recharge cycles than the higher capacity cells. They also seem to hold their charge quite well, so if you charge them to take on a short trip you will find they still contain a full charge after a couple of weeks. I use mine to power a portable DAB radio and they will run for a couple of days .. the DAB radio seems to use quite a lot of power. I also use them in my Nikon camera, the camera slowly drains them but they keep enough power to remember setting for a few months.

rechargeable batteries

I gave five stars because the batteries came charged ready to use. I appreciated that because my keyboard and mouse were very low. Thanks for your smart idea. Will purchase again.

top rechargable batteries !

These are top batteries with perfect performance. Charged them with LiitoKala charger and all 4 of them charged between 2150-2200 mAh !I tested discharge with my high end flashlight which works with AA batteries.First I tested 4 other batteries which are noname with 2400mAh capacity, with 1100 Lumen max setting, flash light worked for only 18 mins!then I tested the Eneloop batteries and with max setting flashlight worked for 45 mins !I would say you cannot find any other battery which will come any closer to this performance at all!
