Compatible replacement battery

This 3.6V Ni-MH pack replaces the original B650 cell in devices that specify a 1200mAh 4.32Wh unit. It measures 50.43 x 42.54 x 14.4mm and weighs 90.3g, matching the factory footprint. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits. Certifications include ISO9001, RoHS, CE, UN38.3 and MSDS.

Fit and alternatives

Suits owners of equipment that lists the B650 part number and requires the stated voltage and capacity. Buyers whose devices call for a different voltage, a higher capacity or a different chemistry should look at other options. The pack is a direct mechanical and electrical match only when the original specifications align exactly.

Deciding specification

The 3.6V 1200mAh rating determines whether this cell will power the target device correctly. If the original battery shows the same voltage and capacity, the replacement will fit and function; if either figure differs, the pack is not suitable.

Questions about this item

How long will the 1200mAh capacity run my device once installed?

The 1200mAh rating means the pack stores 4.32Wh at 3.6V; actual run-time depends on the device's current draw, but it matches the original specification for the B650 model.

What does the 3.6V rating limit in terms of charging and device compatibility?

The 3.6V nominal voltage requires a charger designed for Ni-MH chemistry at that voltage; using a higher-voltage charger can damage the pack and void safety certifications.

Will the 50.43 x 42.54 x 14.4mm dimensions fit my existing battery compartment?

The pack measures 50.43mm long, 42.54mm wide and 14.4mm thick, weighing 90.3g; verify your device's cavity matches these exact dimensions before ordering.
