Description

The JCB 4LR44 is a 6V alkaline battery used in car key fobs, dog training collars, camera light meters, medical devices and security remotes that require a compact 6V power source. The battery consists of four LR44 button cells stacked in series inside a single cylindrical housing, delivering 6V from a package approximately 25mm tall and 13mm in diameter.

Designed for devices where a standard AA or AAA battery does not fit and where 6V is needed instead of the more common 1.5V or 3V cells, the 4LR44 is most commonly encountered in car key fobs for remote unlocking and in pet training collars where the 6V output powers the collar's stimulation circuit. The alkaline chemistry provides stable voltage output over the battery's service life, which varies depending on device drain — typically 1-3 years in a car key fob with intermittent use, shorter in continuously-active devices like dog collars.

This is a single-pack blister containing one 4LR44 battery. The JCB Specialist range uses alkaline chemistry rather than silver oxide or lithium, making these batteries more affordable than premium alternatives while still delivering consistent performance for moderate-drain applications. The battery is not rechargeable and should be disposed of according to local battery recycling regulations when depleted.

Frequently Asked

What devices use a 4LR44 battery?

The 4LR44 is most commonly found in car key fobs for remote locking/unlocking, dog training and bark collars, camera light meters, medical glucose monitors, and some security alarm remotes. If your device specifies 4LR44, A544, PX28A, V4034PX or 28A, this battery is compatible.

How long does a 4LR44 battery last?

Service life depends on device drain. In a car key fob with intermittent use, expect 1-3 years. In a continuously-active dog collar or medical device, the battery may last 3-12 months depending on usage intensity and power draw.

Is the 4LR44 the same as an A544 or PX28A?

Yes. 4LR44, A544, PX28A, V4034PX, 28A, and L1325 are different naming conventions for the same 6V alkaline battery. All are physically and electrically identical and interchangeable.

Can this battery be recharged?

No. The 4LR44 uses alkaline chemistry and is not rechargeable. Attempting to recharge an alkaline battery can cause leakage, swelling or rupture. Dispose of the battery at a battery recycling point when depleted.
