Replacement for Geomax ZTS 602LR

The Estry ZBA-100 is a 6.0V nickel-metal hydride pack rated at 3600mAh and 21.6Wh. It is built to match the original manufacturer specifications for the ZTS 602LR instrument. The pack includes overcharge, over-discharge, over-voltage and short-circuit protection circuits. Surveyors and field engineers who need a direct drop-in power source for this model will find it compatible.

Steady output during long field sessions

The 3600mAh capacity is designed to sustain the instrument through extended measuring routines rather than brief bursts. Protection circuitry prevents voltage sag when the pack is drawn down over hours of continuous operation. Field teams can rely on consistent current delivery until the pack reaches its safe discharge threshold. The chemistry supports repeated deep cycles without the memory effect common in older nickel-cadmium cells.

Rugged enclosure with certified safety

The housing measures 88.75 x 46.53 x 38.02mm and weighs 402.1g, matching the original battery cavity exactly. It carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications confirming toxic-free materials and transport safety. The pack shape aligns with the ZTS 602LR latch mechanism so no shimming or modification is required. Buyers needing a different voltage, a higher capacity or a lithium-ion chemistry should look elsewhere.

Questions about this item

Does the 6.0 V 3600 mAh Ni-MH pack run hot or draw extra power during all-day surveying?

The 21.6 Wh Ni-MH chemistry delivers steady 6.0 V output with low self-discharge, so the pack stays cool and draws only the current your ZTS 602LR requires.

What charger or adapter must I already own to recharge this ZBA-100 replacement?

Any charger rated for 6.0 V Ni-MH packs with the correct polarity connector will recharge the 3600 mAh cell; the battery itself includes over-charge and short-circuit protection.

Will this 88.75 × 46.53 × 38.02 mm pack fit the battery compartment of my older ZTS 602LR without modification?

Yes — the dimensions and 402.1 g weight match the original ZBA-100 spec, so it seats directly in the legacy instrument’s bay.
