PowerexLow Self-Discharge Pre-charged C Rechargeable NiMH Batteries (1.2V, 5000mAh, Pack of 2, MHRCP2)

out of the pack , 1 battery was faulty, quite surprised and disappointed as i have about 50 powered rechargeable batteries and never had issues, after 2nd charging i found 1 battery not functioning well, i i did battery condition ,although the battery charged and read 1.4 v it didn't keep its charge anymore,

"C" sized battery; Summary: These batteries don't seem to reach their rated capacity... (Battery 1: 4964, Battery 2: 4506 mAh)Ironically beat out by the much cheaper Tenergy Premium's that come with a 1 year warranty, I ran this on my Liitokala Lii-500 charger, which can charge 2x C-sized batteries. With up to 1 amp of charge, for my tests I used 500 mA, the charging was done in a large garage where the temperature is ~72F (22C). I ran with "NOR" (normal) mode, which seems to discharge the battery fully, then recharge, and do the test.This is very time intensive.. and for this reason. I get a result after about 1.5 days for each pair. I am also buying a much more modern charger, called the "Xtar DRAGON VP4 Plus", which I will re-test again to see how they compare with newer technology.I am going to return these, for the price premium they perform WORSE than the cheaper ones I bought from tenergy. Add to the fact, battery #2 did not work properly, I had to do the test a second time because the rated capacity the first time came out to somewhere around 2,000 mAh. For what they cost, they should be easily able to outperform the Tenergy batteries.

I've bought several of these over the past couple of years, and they've more than paid back their purchase price. They hold their charge well sitting in standby, and have have a capacity several times that of the (major brand) cells they replaced. The only teensy issue is that these C cells (and the AA cells) are just a scoche bigger than the non-rechargeables, so there's a little squeezing needed getting them in & out. But I've never found a situation where they wouldn't fit with a little coaxing.

I normally like to use the eneloop batteries but they didn't have them in the C size so I went with these Powerex. They work really well for me so far as they hold their charge for a very long time when they are not in use.

I am using these in Luminara candles. These last 3 times as long as my Eneloop AA's with AA-to-C converter sleeves - I timed them. So glad I purchased these. Less time switching out batteries. Well worth the additional cost.
