The AdirPro NiMH Battery for Leica Total Stations is an excellent spare or replacement for the OEM Leica GEB121 battery. It powers up the Leica TPS400, TPS800 total stations and Builder theodolites, such as the T100, T200, R100, R200, R100M and R200M.
It has an output voltage of 6V and 4200 mAh capacity. The charging time is approximately 2.5 hours using the AdirPro GKL112 charger. Surveyors can also charge two batteries simultaneously with the Leica GKL221 in conjunction with the Leica GDI222 adapter.
