Replacement Ni-MH battery 3.6 V 1800 mAh

This Estry 75813 pack replaces the original nickel-metal hydride cell in compatible cordless devices. It delivers 3.6 volts and 1800 milliampere-hours of capacity in a single-unit format. The cell is built to match the original specifications and includes overcharge, over-discharge, over-voltage and short-circuit protection for safer operation.

Practical limits of Ni-MH chemistry

Nickel-metal hydride cells self-discharge faster than lithium types and perform best when cycled regularly rather than stored at full charge. The 6.48 Wh energy rating suits moderate-drain equipment such as handheld scanners or two-way radios. Memory effect can appear if the pack is repeatedly recharged before substantial discharge, so occasional full cycles help maintain capacity.

Build quality and daily fit

The pack measures 129.3 by 23.25 by 23.25 millimetres and weighs 287.0 grams, matching the footprint of the original battery it replaces. Certifications include ISO 9001, RoHS, CE, UN 38.3 and MSDS, confirming compliance with transport and substance restrictions. Buyers whose device requires a different voltage, connector layout or physical envelope will need an alternative pack.

Questions about this item

Should I choose the 1800mAh 3.6V version or a different capacity for my device?

This pack is a single 1800mAh 3.6V Ni-MH unit (6.48Wh). Select it only if your original battery matches 3.6V and 1800mAh; otherwise choose the capacity your device specifies.

What does the 1800mAh rating mean for actual runtime in my equipment?

At 3.6V the pack stores 6.48Wh. A device drawing 180mA would run roughly ten hours; higher loads reduce that proportionally, and Ni-MH voltage drops gradually during discharge.

Does the Ni-MH chemistry limit the charge current or voltage I can use?

Charge only with a Ni-MH charger that terminates at the correct voltage for a 3.6V pack and respects the 1800mAh capacity; the built-in protection guards against overcharge, over-discharge and short circuits.
