Perhaps the most famous standardised battery type in the world.

Rechargeable NiMH batteries

Project Farm has made multiple videos:

  • Overall seems to recommend Harbor Freight 2200 and Amazon Basics Silver 2400

• Which AA Rechargeable Battery is Best after 1 Year?

In my experience teaching households to use them has been troublesome. Cool Tools website suggests having many of these batteries in stock to encourage households to use them. https://kk.org/cooltools/eneloop-batteries-in-bulk/
