The single specification that decides fit is the 10000mAh capacity combined with the 3.7V rating. If the original battery shows the same milliampere-hours and voltage, this replacement will match the electrical requirements.

Questions about this item

Will the 181.0 x 66.0 x 8.4 mm dimensions let this battery fit my existing TST-902 chassis without modification?

The pack is built to the original 181.0 x 66.0 x 8.4 mm footprint so it seats in the standard TST-902 bay exactly as the factory unit did.

How can I verify the replacement is delivering the rated 3.7 V and 37.0 Wh after installation?

Check the battery manager in your OS — it should report a design capacity near 37.0 Wh and a nominal voltage of 3.7 V when the pack is fully charged.

Does the box include the BL1880F6835661S5PG9T cell pack only, or are mounting screws and a connector cable also supplied?

The package contains the 10000 mAh lithium-polymer cell pack; any screws or cables needed for your specific TST-902 variant must be sourced separately.
