PISKEKAT B3V 1A 290 mAh replacement battery pack of 12

Replacement pack for MS-4 and MS-5 collars

This pack contains twelve B3V 1A cells rated at 290 mAh each. They are built as direct replacements for the batteries used in High Tech electronic collars of the MS-4 and MS-5 series. The design includes protection against damage if a cell is inserted the wrong way round. Buyers who need a different voltage or a higher capacity than 290 mAh should look elsewhere.

Leakproof cells with very low self-discharge

Each cell is leakproof and loses less than one percent of its charge per year when stored at room temperature in the original packaging. This makes the pack practical for keeping spares on hand without frequent recharging. The chemistry is not suited for devices that draw more current than the collar's normal operating profile.

Check collar model and quantity needed

Confirm that the collar is an MS-4 or MS-5 unit before ordering, as the B3V 1A form factor fits only those models. Verify how many cells your collar or charging station requires so the twelve-cell quantity matches your maintenance schedule. No charger is included with this pack.
