Reliably takes and holds a charge
In my experience: holds more charge for a longer period of time. My handheld gps lasts much longer with these than with my Walmart-purchased rechargeables. Although all rechargeables have a shelf-life, I have not yet had to throw out one of these due to diminished capacity. I use and recommend the MAHA Powerex Wizard, in order to maximize the usable life of all rechargeable AA and AAA batteries.
