Replacement Battery for Leica Survey Equipment

The FYIOGXG replacement battery delivers 1200mAh capacity at 12.0 volts for Leica TC400-905 and TPS1000 instruments. It matches original part numbers 439149 and GEB77 with a fully decoded chip for direct compatibility. Nickel-zinc chemistry provides 14.40Wh energy in a 71.42 x 54.52 x 32.92mm form factor weighing 221g.

Nickel-Zinc Chemistry and Voltage Constraints

Nickel-zinc cells operate at a fixed 12.0 volt output that cannot be adjusted for other voltage requirements. The 1200mAh capacity limits continuous runtime compared to higher-capacity alternatives. Users needing extended field sessions without recharging will find the capacity restrictive. The chemistry also requires specific charging profiles not supported by generic chargers.

Capacity Decides Field Duration

The 1200mAh rating is the single figure that determines how long a Leica TC400-905 or TPS1000 operates between charges. Survey crews planning full-day sessions must calculate whether this capacity meets their duty cycle or if spare units are essential. No other specification alters the practical runtime of this battery.

Questions about this item

How do I know this 1200mAh 14.40Wh pack is the right one for my Leica unit?

Match the original part numbers 439149 or GEB77 and the device models TC400-905 or TPS1000 printed on your current battery.

What runtime can I expect from the 12.0V 14.40Wh rating in field use?

The 14.40Wh capacity at 12.0V delivers the same energy as the original GEB77 pack for survey and test sessions.

Does the nickel-zinc chemistry need a special charger or standard Leica charger?

The built-in decoded chip works with the standard Leica charger for the TC400-905 and TPS1000 series.
