Psst… wanna save some money? How about have a set of fully charged batteries ready whenever you need them? And keep toxic waste out of landfills? Then it’s time to make the switch to next-generation, high-performance rechargeable batteries. Read on for Modern Enviro’s top picks.
Browse through reviews of the best rechargeable batteries and it’s clear that new “low self discharge” models are a HUGE improvement from older designs. These nickel metal hydride (NiMH) batteries retain their charge through years of storage; they deliver better, more consistent performance in household devices; and they can be recharged hundreds or even thousands of times.
Eneloop Rechargeable Batteries By Sanyo
Eneloop rechargeable batteries from Sanyo have set the industry standard for low self discharge models since they hit the market five years ago. They retain 75% of their charge after 3 years of storage, and they’re available in AA and AAA sizes (adapter modules are also available to use Eneloops in place of C batteries or D batteries).
