BONAI AA Rechargeable Batteries 2800mAh 1.2V Ni-MH Low Self Discharge (8-Pack) - Long Lasting Power for Cameras, Toys, Flashlights & Electronics

I did a full proper discharge capacity test* (not merely a charging capacity test) of 8 of them when new and got 2118 to 2209 mAh. After several charge-discharge cycles I measured again and it went down to 2093 to 2158. Another cycle and I measured four of them at 2116 to 2190 mAh. Another cycle and it went to 2127 to 2201. Another and 2134 to 2210. Then 2137 to 2215. Still increasing very slowly but let's call it around 2175 mAh so far.FYI, the Amazon Basics high capacity 2400 mAh batteries measured very close to 2400 mAh.(*in Test mode using my "Dlyfull Smart Battery Charger for AA AAA Ni-MH Ni-CD Rechargeable Batteries with Discharge, Test, and Refresh Functions, LCD Display and USB Cable",which, btw, is itself a very good charger/tester/reconditioner for nimh aaa/aa and a fantastic value)Died really fast after few usage seems to me that they dont really hold 2800 but myabe im wrong?I've got a 3-4 year history with this brand of battery, we're using them in RF mics for 'professional' settings, and get excellent runtime in our shure qlxd. Much better than constantly buying and discarding disposable AA. This is my 5th set of these in service, to replace the very-first set which were charged to death after being abandoned onsite for 18months during the pandemic. Would recommend.Not AA Diameter. Had problems useing in C & D adapters. Needed to force batteries in to use them, only to break the adapter. when removing battery. Will Be Returning...UPDATE: reached out to seller. They Were Willing to refund the full price of batteries and for me to keep the batteries. As fate would have it purchased electric heated socks for girlfriend as a Christmas present and they required six AA high capacity rechargeable batteries. Batteries work great in the socks and recharge easily updating my review from one star to four stars.Using batteries for candles, batteries require charging every 2 days average 8 hrs daily. Prefer longer charge.These batteries are the best that I have owned. They last longer, and hold their charges longer than any of the competitors' products.Good batteries at a good price.They say it’s long lasting but but it’s not it’s discharge fast
