Eneloop rechargeable batteries
Save money and reduce waste by using rechargeable batteries! Panasonic’s Eneloop batteries are some of (if not the) best! All Eneloop batteries come precharged and are available in AA and AAA sizes, and you get can spacers for C- and D-sized needs.
The newer “Advanced Charger” charges each battery individually, so you don’t have to stress about pairing batteries of the same discharge level.
These normal Eneloop batteries can be charged up to 2,100 times! And of the dozens of Eneloop batteries I’ve purchased over several years, only one has truly died. I’ve saved hundreds of dollars this way!
Eneloop batteries are available in many different packs and quantities, as well as higher capacities, but I’ve found the Super Power Pack to be the best value and for starting.
