Compatible replacement for Testo 350K analysers

This lithium-ion pack replaces the original 0515 0039 cell used in Testo 350K portable emission exhaust gas analysers. It delivers 11.1 V and 5.2 Ah capacity in a black housing. The unit is brand new and built to OEM-compatible specifications.

Fits directly into the analyser battery compartment

The pack measures 133.50 x 54.30 x 26.30 mm and slots into the instrument without adapters or wiring changes. Its 57.72 Wh rating supports extended field sessions for emissions testing. No external charger or cradle is required beyond the analyser's own charging circuit.

The package contains one 5.2 Ah Li-ion cell only; cables, mounting hardware or software are not included. Installation is a direct swap of the depleted original. Users needing continuous operation should plan for a second pack or access to the analyser's mains charger.

Questions about this item

How long will the 5.2 Ah battery run the Testo 350K analyser before it needs recharging?

The pack stores 57.72 Wh at 11.1 V, giving roughly five hours of continuous operation on the 350K depending on sensor load.

Does the battery get hot or noisy when the analyser runs all day?

The Li-ion cells produce no audible noise and only warm slightly under normal load; the analyser’s own fan handles any heat.

What charger or cable must I already have to use this battery with the Testo 350K?

The battery slides straight into the 350K’s compartment and charges inside the instrument using the analyser’s standard mains adapter.
