Review on BONAI Rechargeable Batteries Capacity Battery by John Bosch

My daughter has a music box that she MUST fall asleep in (Little Einstein underwater box). When we first got it we put new batteries in at least every 2 weeks because it's a power hungry item and she uses it like hell. So I turned to BONAI batteries and chargers to save money. I've been charging and turning these batteries about every 2 weeks for over a year now and they're still working. (The box accepts 4 batteries at a time and bought 8 packs of C). It takes about 6 hours to charge, which doesn't bother me since I left it on all night. 08/13/2018 was my original purchase and today (02/01/2020) I went back to buy more. Not because the first 8 are worn out, but because we now have another daughter who uses the same music box and needs more sets in rotation. Highly recommended!
