Description

The Panasonic LRV08 is a 12V alkaline battery in the 23A format, measuring approximately 28mm in length and 10mm in diameter. It delivers reliable power to car key fobs, wireless doorbells, garage door openers, and small security devices that require a compact 12V cell. The alkaline chemistry provides consistent voltage output across the battery's life.

Designed for devices with intermittent draw rather than continuous high-current loads, the LRV08 suits applications where the battery sits dormant for weeks or months between brief power demands. Car remotes, alarm fobs and wireless doorbells typically draw power in short bursts measured in milliseconds, making this battery chemistry well-suited to those use cases. The mercury-free construction meets current environmental standards.

Panasonic rates the LRV08 with a shelf life of up to 10 years when stored at room temperature, meaning batteries can be kept as spares without significant capacity loss. The operating temperature range of -20°C to +65°C covers standard UK seasonal variation as well as storage in unheated garages or vehicle glove boxes. The battery is also sold under alternative designations including 23A, 23AE, A23, V23GA and MN21 depending on manufacturer and region.

Frequently Asked

What devices use the LRV08 battery?

The LRV08 powers car key fobs, wireless doorbells, garage door remote controls, small security alarm fobs, and some medical devices. It's the same as a 23A battery, so any device specifying 23A, A23, MN21 or V23GA will accept the LRV08.

How long does the battery last in a car remote?

Battery life depends on usage frequency. In a typical car key fob used 10-20 times per day, an LRV08 generally lasts 12-24 months. Less frequent use extends this further. The 10-year shelf life means spares can be kept without degradation.

Can it be used in cold weather?

Yes. The LRV08 operates across -20°C to +65°C, covering typical UK winter conditions and summer heat. Performance may reduce slightly at the extremes of this range but the battery remains functional.

Is it rechargeable?

No. The LRV08 is a single-use alkaline battery and must not be recharged. Attempting to recharge alkaline cells can cause leakage or rupture. Dispose of used batteries at household recycling centres or battery collection points.
