Trimble Juno replacement battery

This Li-Polymer pack is built for Trimble Juno 3 series handhelds including the 3A through 3E and the TNJ31. It replaces original part numbers 707-00008-00A, 707-00008-00B and 85713-00 with a 3.06 Ah cell rated at 3.7 V. Surveyors and field crews who rely on these GPS units for daily data collection can swap the pack without tools.

OEM-compatible single pack

The box contains one black battery measuring 64.38 x 48.96 x 10.42 mm and nothing else. No charger, cable or mounting hardware is bundled, so existing charging cradles and vehicle adapters must be reused. The 100 % OEM-compatible claim means the cell fits the original compartment and communicates with the device fuel gauge exactly as the factory unit did.

3.7 V Li-Polymer limits

Li-Polymer chemistry at 3.7 V nominal voltage delivers 11.32 Wh in this form factor, which caps runtime for power-hungry GNSS logging sessions. The pack cannot be fast-charged beyond the host device’s built-in controller and will degrade if stored fully charged in high heat. Users needing multi-day autonomy must carry spares or an external power bank because the internal cell is not user-expandable.

Questions about this item

When will the 3.06 Ah Li-Polymer battery need replacing?

After several hundred charge cycles the capacity will drop below usable levels, at which point a new DS-CS-TRN300SL pack is required.

What limits continuous operation of the 3.7 V 3060 mAh pack?

The 11.32 Wh energy capacity sets the runtime ceiling; sustained GPS logging will drain it in a single field session.

Does the 64.38 x 48.96 x 10.42 mm battery get hot or noisy during all-day use?

Li-Polymer chemistry runs silently and stays near ambient temperature; no fan or active cooling is present.
