BONAI Rechargeable Batteries D LR20 10000mAh Ni-MH 1.2V Accu, Type D Baby D LR20 Rechargeable Battery 1200 Cycles, Low Self-Discharge Long Life (4 Batteries)

Theses are excellent batteries. I've never had any issues with theses D Rechargeable batteries. But like sometimes things go do wrong with faulty items. Which is what happened in my case. But the seller contacted me and offered to replace them with out any questions or quibbles. So I can honestly say I recommend these batteries and top aftermarket customer services you get afterwards too. I've bought batteries in the past from other sellers. But I won't be swapping this seller for the love of money. Excellent products. And best of all is the customer after services. Five Shining Stars Added.

Perfect

We've used amazon basic rechargeable batteries for years but our catflap batteries need changing every 3-4 weeks and it's sods law that I don't notice until I'm about to go to bed and feel guilty as sin that PratCat will end up stuck outside if the batteries run out during the night. I wanted some spares so I can charge one pack while the replacements go into the catflap. These were pretty cheap and as we use a lot of rechargeable batteries in our house ( sylvanian families , toys, nightlights, torches the list is never ending!) I thought I'd get these and the charger that comes with them so I can just get everything done in one go. Really pleased with them and can't fault the sellers service. I accidently bought the D size and had to return them. They covered the postage and as soon as I'd sent them back using the prepaid returns form they provided me, they sent me a full refund immediately the same afternoon! Great service and a good product.

bought these batteries for my habbitat wall clock as normal batteries only lasted a few days so i bought these rechargable batteries great buy long lasting charge would highly recommend

Batteries didn't seem to last long. Got a new charger which displays how they are charging and 1 if the batteries isn't charging properly.

These are very good to the expensive duracell one's (non rechargable). only gripe is one seems to run out fairly quickly but rest are fine. I would recommend these for sure.

These claim to retain 90% of charge after a year. I have attempted to use these twice during the last year and both times found them to flat to operate the appliance. Testing them with a battery charger, two of the four showed a little remaining charge, the other two none. When complaining about this they offered a refund but commented "... If it is not used for a long time, it is recommended to charge the battery every 3 months. Otherwise, the battery voltage will drop below 1.1V and it will be scrapped and cannot be used." So they advertise them as holding charge for years but recommend recharging after 3 months. That's not dishonest. Don't buy for infrequent use.

I cannot give a right feed back because even if I have a right size rechargeable this are not fit, so never going to be able to use, unless buy different charger.
