Batteries can be a pain... they can also put a strain on the wallet. We found this unique version of rechargeables to be an excellent alternative to purchasing one time use batteries.The quick 1 hour charging time and consistent 1.5V are game changing. Designed for performance, convenience and reliability, Paleblue’s AAA batteries will help you reduce waste, save money, and save time. One thing I really enjoy is the single charging cable with 4 way splitter. No weird plastic charger that needs to be plugged into a 120v receptacle.
