BONAI LCD Smart Battery Charger for C D AA AAA 9V NiMH NiCD Rechargeable Batteries with Refresh Function

Lo compre a mediados del 2021 y a la fecha sigue funcionando, lo compre en un principio para cargar baterias de Amazon, pero después lo utilice con las Sony y de otras marcas y me funcionó, ojo hay que mantener el cargador en un lugar seco ya que se oxida, lo metí en una bolsa de plástico para que eso no pasará y hasta ahora funciona bien

Reasonably priced charger, charges fast, also bought their rechargeable AA batteries too. A+

I've rechargable batteries of this same brand. So, I ordered this product because it's very useful for me. This charger is extremely useful for me and best in design. It can charge all sizes of batteries like AA, AAA, B, C and 9V. The best part of this charger is it's smart LCD display which shows how much the batteries are charged with 3 marking accuracy so I can know how much charge has been done or left. There's one blue button given besides the display to start charging or to discharge batteries. This is also shown in the display that if it's charging, discharging or error. It shows error if the battery is wrongly inserted or broken. This battery charger has over charging protection, over heat protection, over voltage protection, over current protection and short circuit protection so I don't have to worry about even if I forget to remove batteries when they are fully charged. I have 2800 mAh batteries and it took between 2.5-3 hours to fully charge all of this batteries at once. Taking all of these things together, it's perfectly designed product I've seen so far.

I bought this only because I can use it to charge AA, AAA, C, D types and also the 9V battery. Best part is just charge one battery and not two like the current standard battery chargers. Only weird part is a tick sound that is audible only if the surrounding is quiet, but then I don't know how electronic stuff works so I can't be concerned but only curious. Maybe they will mention it in their booklet next time. I really really hope this product lasts a long time

Good charger
