Replacement lithium battery

The Estry TST-902 is a 10000mAh 3.7V lithium pack built to match the original specifications for the TST-902 device. It carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications and includes overcharge, over-discharge, over-voltage and short-circuit protection.

Who this fits and who it does not

This pack suits owners of a TST-902 unit who need a direct replacement with the same voltage and capacity. Buyers whose equipment requires a different form factor, a higher or lower voltage, or a different part number should look elsewhere.

Critical specification match

Questions about this item

How often will the 10000mAh lithium cell need replacement under normal use?

The 10000mAh 3.7V lithium pack is rated for hundreds of charge cycles; replace it when run-time drops below your needs.

What stops the TST-902 from running longer during continuous discharge?

The 37.0Wh capacity and built-in over-discharge protection set the hard runtime limit.

How warm does the 315.8g battery get when powering a device all day?

The 181.0 x 66.0 x 8.4mm pack stays near ambient temperature thanks to low internal resistance and over-voltage safeguards.
