Replacement Ni-MH battery for TN5100 series

This Estry TN5100F0 pack supplies 2.4V and 2000mAh capacity for cordless devices using the listed compatible models. It matches the original specifications and dimensions of 49.0 x 29.0 x 14.5mm. The unit weighs 91.5g and carries ISO9001, RoHS, CE, UN38.3 and MSDS certification.

Sustained discharge and protection

Ni-MH chemistry delivers steady voltage through the discharge cycle rather than a sharp drop-off. Built-in overcharge, over-discharge, over-voltage and short-circuit protection helps maintain cycle life during repeated daily use. The 4.8Wh rating supports extended runtime between charges for compatible handsets or equipment.

Upgrade from lower-capacity packs

Users replacing a depleted original pack or a lower-mAh alternative gain longer talk and standby time. The jump is worth it when the device sees heavy daily cycles and the original runtime has fallen below usable levels. Buyers needing a different voltage or form factor should verify compatibility before ordering.

Questions about this item

Does the 2.4V 2000mAh Ni-MH pack run warm when powering a device continuously?

The pack is rated at 4.8Wh and weighs 91.5g; Ni-MH chemistry generates only modest heat at typical discharge rates, so it stays cool during all-day use.

What must I already own for this 49.0 x 29.0 x 14.5mm battery to work?

You need a device that accepts a 2.4V Ni-MH pack with the listed dimensions and connector, such as the TN5100, TN5120 or TN5140 series models.

Will this replacement cell fit alongside the original charger I kept for my TN5100F0 unit?

Yes, the voltage and capacity match the original specification, so the existing charger will charge the new pack normally.
