How long can these batteries sit in storage?

Energizer rates MAX alkaline cells for up to 10 years of shelf life, so spares kept in a drawer stay usable for years.

Are they good for high-drain devices?

No. They suit remotes, clocks and small electronics. For flashes, motorized toys or gaming controllers, Energizer Ultimate Lithium or rechargeable NiMH cells last longer.

Energizer builds MAX with leak protection, and owners report few leaks in devices left sitting. No alkaline is leak-proof if left dead in a device for years, so remove spent cells.

No. These are single-use alkaline batteries. Recharging them is unsafe; use Energizer Recharge cells if you want reusable AAA power.

What devices take AAA batteries?

TV and AC remotes, wireless mice and keyboards, small toys, blood pressure monitors, clocks and LED string lights commonly use AAA cells.

How does MAX compare with Duracell?

Both are mainstream alkalines with similar runtimes in low-drain devices. Duracell Optimum targets high-drain use; Energizer MAX is the everyday option, and the better pick is usually the one on hand.
