Zinc carbon batteries are more commonly used in low-drain devices, whereas the Panasonic alkaline range spans the entire appliance spectrum: from low- to high-drain.

A battery is a chemical product which produces electricity by chemical reactions at its inside. These reactions and its inside materials do deteriorate over time. If you start using it within that period, the battery will operate normally and maintain the specified performance.

Each battery has specific characteristics, depending on their chemical composition. Zinc carbon is a cheap battery for basic low-drain devices. Alkaline deliver good, dependable power (usable for any type of device, depending on the alkaline type). Lithium technology is a stable technology for smaller, yet demanding appliances. Zinc Air provide long-lasting, continual power.

Yes. All batteries have an expiration date, beyond which their performance decreases.

Panasonic does not produce or sell 12V batteries like A27, 27A, G27A, MN27 or bi09 of other manufacturers.

If service time has reduced to half of its initial capacity or if charging time never seems to complete, it’s probably time to replace the battery.

0006P is a 9V (square) battery and is also designated as a 6F22 (Zinc carbon) or 6LR61 (Alkaline) battery.

The memory effect is an occasional defect, which occurs in Ni-Cd and Ni-MH rechargeable batteries, where the maximum battery voltage decreases even though the original power of the battery remains the same.

Never use Ni-MH rechargeable batteries for waterproof appliances, appliances specifically designed for alkaline batteries, or in appliances with battery indicators.

Never try to charge Panasonic lithium coin batteries, as they cannot be recharged.
