Replacement Battery for Testo 320 Analyser

This lithium-ion cell replaces part 0515 5046 in the Testo 320 combustion analyser. It supplies 3.7 V and 2.6 Ah for field measurements. The blue casing matches the original equipment colour.

Practical Limits of Li-ion Chemistry

Capacity falls at low temperature and after many charge cycles. The pack has no built-in fuel gauge, so runtime must be estimated from instrument use. Self-discharge during long storage will require a refresh charge before the next job.

2600 mAh Capacity Decides Fit

The 9.62 Wh rating determines how long the analyser runs between charges. If your daily test schedule exceeds this energy budget, you will need a spare cell or mains adapter. Buyers who need longer continuous operation cannot meet that need with this pack.
