Replacement Battery for Juniper Mesa Field

This 7.4 V lithium-ion pack replaces the original battery in Juniper Mesa Field and Topcon Tesla survey equipment. It matches the OEM part numbers 20545 and 61117 and uses a fully decoded chip so the device recognises it immediately. Surveyors and field technicians who need a direct drop-in replacement will find it compatible without modification.

Sustained Capacity and Protection on Long Field Days

The 2600 mAh cell delivers 19.24 Wh of energy for extended measurement sessions between charges. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits, helping the pack maintain stable output across a full work shift. A fresh battery reaches its best runtime after two or three complete charge and discharge cycles.

Upgrade from a Worn or Swollen Original Pack

When the factory battery no longer holds a charge or shows physical swelling, this unit restores the instrument to its original runtime. It is not suited for users who need higher capacity than 2600 mAh or a different voltage platform. The pack fits the existing battery cavity measuring 74.00 x 39.40 x 21.00 mm and weighs 103.8 g.

Questions about this item

Does the 7.4 V lithium-ion cell run hot during a full day of field surveying?

The pack is rated at 7.4 V and 19.24 Wh with a mass of 103.8 g; normal operation stays within typical lithium-ion temperature limits for survey equipment.

What must I already own to use this replacement battery?

You need a Juniper Mesa Field or Topcon Tesla device that accepts part numbers 20545 or 61117 and a compatible charger for 7.4 V lithium-ion packs.

Will the decoded chip work with an older Topcon Tesla unit I still use?

The fully decoded chip is designed to match the original battery specification for the listed part numbers, so it functions like the factory pack in those devices.
