Do these last longer than other batteries with the same mAh rating? I have purchased the Amazon brand rechargeables (2000mAh) but they drain fast.

Hey J YO,It's hard to say. I haven't actually charged them yet. I used them out of the package, factory charge and they are STILL going. I'll update you once I charge and use them a couple times. The factory charge, thus far, is our performing ANY rechargeable I've ever used, and any alkaline, for that matter. It also may be the charger though. I did not purchase a new charger for these batteries as I already have two. Have you been charging yours with an old charger?

If your Amazon cells are the black labeled, that could be why they drain fast considering those cells i believe are made in China. Eneloops on the other hand will stay charged and work well just like Panasonic advertises.

They definitely seem to last longer than my Duracells! And I do not think they drain all that fast, they seem to hold up pretty good. And they were made in Japan!

They last quite a while. I mainly use them for my son's wireless remote for his Xbox 360, he plays everyday, somedays he plays allday and on average we usually have to recharge them every 3-4 months. I found them to be better than an OEM battery we've had.

They last quite a long time, actually. I use NiMH rechargeables, and it's usually several months between recharges.

Mine are lasting for over 1.5h and they outrun oem GoPro batteries by just few minutes. The real test comes after several charges but I don't have any complains so far. Good luck with your shooting;)

I suppose it depends on the brand and how much its discharged. Mine have averaged 3-4hrs... but they weren't completely depleted.

These are a high quality battery. Youre looking at a long shelf life. Right around 10 years or so. Obviously this varies depending on storage and brand quality. And of course they will slowly loose some energy every year. They are high quality reliable battery. Thats why they started getting used in flashlights; was due to the long shelf life.

There are higher output non-rechargeable batteries. These wouldn't power a device I have which will run for about 8 hours with Energizer Ultimate Lithium. I'm groused I can't seem to find a rechargeable that'll power the device.

They're rated at 2000mAH's but average is 1900mAH's. Depends on your application though.

I have used these batteries for almost 2yrs now. I have had no issues with them at all. They charge quickly and last for days.

Mine work just fine. I'm not sure if the charge value is accurate, as I've never drained it below halfway. They last a long time!

No, So far my batteries have lasted longer than other brand name batteries.

Depends on how you [ab]use them. If you often run them all the way down, and/or run them down only 1 or 2% and back up to 100%, they may last less than a year (or only take half a charge after a while). If you seldom run them below 30%, and don't recharge until they're 90% or less, they may last 5 years or more.

I bought these same batteries in May 2012. I recently ordered these again. (different supplier) I did not have any complaints or would not buy them again. Any brand battery can have a bad cell in the pack. I also like Renata brand. (not sure I spelled that correctly) Another choice would be Energizer. These 3 brands seem reliable over the years.

I'm using Panasonic eneloop 2000mah rechargeable, which is low discharge battery and they are still going strong after month. Will update when they need recharging. I used the Maha MH-C9000 to cycle and charge them as well.

These last as long as my gold versapak batteries. That being said, none of the versapak type batteries have a long life under heavy load.

I charge them all the time. I'm sure it may take longer than lower output batteries but I have not measured the difference.

Hello, El Jefe, These batteries last a long time in my Rosewill 3 "D" Cell, Cree-LED Flashlight. I don't use the light all the time, but it is very bright, and the charge lasts for months. I use an Ansmann energy16 charger. I have used a pair of them in the ignition part of our kerosene heater, and they too, have lasted a long time. I have never recharged them since they begin lighting up our heater. I really like these batteries.
