Replacement battery for TriSquare radios

This 4.8V 800mAh nickel-metal hydride pack replaces the original TSX-BP cell in TriSquare TSX100 and TSX300 two-way radios. It delivers 3.84Wh of energy and matches the factory voltage and capacity specifications. The pack measures 49.29 x 42.78 x 13.68mm and weighs 106.5g.

Who this suits and who should look elsewhere

Owners of a TSX100 or TSX300 who need a direct-fit replacement will find the correct voltage, capacity and connector. Buyers with other radio models or a different battery part number cannot use this pack. Anyone requiring a higher capacity or a different chemistry should consider other options.

Deciding specification: 4.8V 800mAh Ni-MH

The single figure that determines compatibility is the 4.8V 800mAh nickel-metal hydride rating. Only devices designed for this exact voltage and chemistry will operate correctly and safely. Verify the original battery label reads 4.8V and 800mAh before ordering.

Questions about this item

How do I install the TSX100 battery in my TSX100 or TSX300 radio?

Open the battery compartment, remove the old pack, insert the new 4.8 V 800 mAh Ni-MH battery matching the TSX-BP part number, and close the latch securely.

What maintenance or replacement will this 4.8 V 800 mAh Ni-MH pack need later?

Recharge it before storage, avoid leaving it fully discharged for long periods, and replace the pack when run-time drops noticeably below the original 800 mAh capacity.

What limit appears first during sustained use of this 4.8 V 800 mAh battery?

The 800 mAh capacity determines how long the radio operates before the voltage falls below the usable threshold and the pack requires recharging.
