10.8 V 7800 mAh Replacement Battery

The KingSener Li202SX-7800 is a new lithium-ion pack rated at 10.8 V and 7800 mAh (84.24 Wh). It is built as a direct replacement for the original battery used in TSI AeroTrak APC 9510-02 and DustTrak II 8530, 8531, DRX 8533 aerosol monitors. The black casing matches the original dimensions so no modification is required for installation.

Suits TSI monitor operators needing a fresh 7800

This pack serves technicians who must swap a depleted battery in the listed TSI instruments and want the same 7800 mAh capacity. It does not serve users whose device calls for a different voltage, a different form factor, or a capacity such as 6600 mAh, 7200 mAh or 8700 mAh, because those variants are not interchangeable with this model.

Capacity is 7800 mAh at 10.8 V

The single figure that decides fitment is the 7800 mAh capacity combined with the 10.8 V nominal voltage. Only equipment designed for this exact rating should use the Li202SX-7800; any other rating will not match the original specification.

Questions about this item

How do I install the Li202SX-7800 battery in my TSI AEROTRAK APC 9510-02, and what step do people often miss?

Insert the battery into the compartment until the latch clicks; the step users miss is performing 2 to 3 full charge and discharge cycles at low current before regular use.

What maintenance will the Li202SX-7800 need after months of storage?

If stored for a long period, charge the battery to more than 80 % at least once per month and keep it out of hot or humid conditions.

What is the first limit I will hit when running the Li202SX-7800 continuously in a DustTrak II 8530?

The 7800 mAh capacity at 10.8 V (84.24 Wh) determines runtime; sustained high-current draw will deplete the charge before any thermal limit is reached.
