Alternatives

• Rechargeable AA (NiMH)— Cheaper over time; lower voltage can affect some devices.

Maintenance notes

• Use lithium primaries in cold or long-stored kits — they resist leaking.
• Check dates and swap corroded cells.

Buying considerations

• Standardizing on AA (and AAA) lets kit items share spares.
• Lithium AAs weigh less and last longer in cold than alkaline.
