Replacement NiMH battery for Leica surveying gear

The Centenex Electronics BALEICAGEB121_ATB121 is a 3600mAh 6V nickel-metal hydride cell built to replace the Leica GEB111 and GEB121 packs. It matches the original 21.6 Wh rating and the 89.05 x 46.46 x 37.91 mm footprint so it seats directly in the instrument battery compartment. The pack is sold new and rated as 100 percent OEM compatible for a straight swap without wiring changes.

Field crews using DNA03 DNA10 TPS series

Surveyors running Leica DNA03 DNA10 TPS300 TPS400 TPS700 TPS800 TPS1100 or Palm IR225 IR250D IR500D instruments can use this cell as a direct replacement. Teams needing lithium-ion chemistry or a higher capacity than 3600mAh should look at other power solutions because this pack stays with standard NiMH output. The single-unit quantity also means multi-bay chargers will need additional packs purchased separately.

3600mAh 6V NiMH capacity decides runtime

The 3600mAh 6V nickel-metal hydride rating delivers 21.6 Whr of energy which determines how long a total station or GPS receiver operates between charges. If the field day demands more watt-hours than this figure provides the operator must carry spares or choose a higher-capacity chemistry. The fixed voltage and chemistry also lock the charging profile to existing Leica NiMH chargers.

Questions about this item

How often will the 3600mAh NiMH pack need to be replaced under daily survey use?

Expect two to three years of regular charge cycles before capacity drops below useful levels for Leica TPS and DNA instruments.

What limit appears first when the battery powers a Leica TPS-1100 continuously?

The 21.6 Wh rating typically delivers a full field day; voltage sag under heavy radio use is the first sign the pack needs recharging.

Does the 89.05 × 46.46 × 37.91 mm case run hot or make noise during all-day operation?

NiMH chemistry stays cool and silent; the pack warms only slightly during extended GPS or total-station sessions.
