BONAI 2800mAh AA Rechargeable Battery NI-MH 1200 Cycles High Capacity Rechargeable aa Batteries, Pack of 24

Hard to write a review of batteries but they do exactly what they say and the price seems a bargain.

Reliable rechargeable batteries.

Have been using rechargeable cells for years starting with NiCd cells in the early 90’s through NiMh versions till now.Discovered low self-discharge cells from Energizer and Uniross about a decade ago. I was really impressed as generally rechargeables though useful was not that great due to the discharge characteristics and were flat before I knew it.The technology was too expensive at the time though and I didn’t convert.I finally converted a year or 2 ago when prices become more reasonable. Brought into Sanyo/Panasonic Eneloop cells and have been using them since.Recently, I was looking for higher power versions, but found that the “Pro” variants to be prohibitively expensive.Found these on the recommendations tab and decided to give them a try. I purchased two 24 packs of AA (2800mAh) and also AAA (1100mAh).Wanted to test the actual capacity of these and put them into my charger to test. I also tested examples of my existing low discharge NiMh cells for a comparison.Have put the results in a table for you.The 2 AA’s were around 2400 mAh which was about 12 – 13% below the 2800 mAh claimed.So these cells have come out lower than their stated capacities, while the other cells I have had broadly outperformed their stated values.On the surface, this may seem that these cells have overegged their values but you need to bear in mind that this was the first time I had used these cells and their capacitates may get better over time (The other cells tested have been through quite a few charge/discharge cycles).On another note, I have only tested 2 Bonai AA’s and 3 AAA’s plus one of each of the other brands. This is not a comprehensive test in any way shape or form but I would still say that it gives us a relatively good idea of their performances.In my opinion, even if these figures are indeed the true values of these cells, I don’t think it should put you off because if you take into account value for money, these are still really good.With regards to discharge rate, I won’t be able to know until I use these for a few months.I would give these 4 out of 5 because of the shortfall from the stated capacity but they still represent great value and I would recommend to you.

The batteries are all OK, don't know how long they will last yet.Very happy

Bought for our camera flash units at work and they are lasting well

After about maybe 10 charges two of the battery’s failed to take a charge and those that do the charge doesn’t last that long. Quite disappointing and won’t buy this make again

Fast charger gets from 0 to 100 in approx 1 hour

I use them in an outdoor camera. They can last anywhere between 2 weeks and 6 months, which is what the camera manufacturer says should happen. So that's good. My first set lasted 5 years before deciding to give up ... so I bought another set. Good batteries.
