After 7yrs of use, the batteries in my Bodygroomer finally died! They refused to recharge. The batteries in my unit were green colored Suppo HSY-AAA0.75-PHP NiMH 750mAh. I replaced them with Eneloop AAA 800 mAh, bought for $5.70 off Lazada Thailand, for a 4 pack. Because I’m not home, I wasn’t able to solder. I used electrical tape instead. The battery pack has a snug fit in the unit, so I’m hoping the electrical tape holds. Once I return home, I’ll solder the connections. Disassembly was not difficult for me. My biggest issue was prying the metal tabs off the batteries. I used a pocket knife to scrape them off, being extra careful not to break them. The eneloops came pre-charged, so I was able to see if the bodygroomer turned on, and I did. It’s currently on the charge stand. Thanks for the “How To!”
