Lithium Metal Battery

2026‑01‑11

This is a quick review of compact lithium primary (non-rechargeable) batteries (eg, AA and AAA). Basically, I don’t buy akaline cells anymore.

Advantages:

  • won’t leak
  • 1.5x capacity of alkaline cell
  • long shelf life
  • long service life

Disadvantages:

  • 2x price of alkaline cell

Warning:

  • don’t attempt to recharge!
