Protection Features and Packaging

The battery includes overcharge, over-discharge, over-voltage and short-circuit protection circuits to extend service life. A new unit reaches optimal performance after two or three full charge and discharge cycles. The package contains shock-absorbing foam to protect the cell during transport. No additional accessories or software are bundled with this single-cell replacement.

Compatibility Checks Before Ordering

Verify the model number of your device and the part number PL052535 on your existing battery before purchase. Ensure the connector aligns correctly when installing the new cell. Avoid using low-quality third-party chargers, which can reduce battery lifespan. Do not disassemble the pack, expose it to fire or water, or store it above 60°C.

Questions about this item

How often should the 370mAh lithium-ion cell be cycled to maintain capacity?

The manufacturer recommends 2 or 3 full charge and discharge cycles when the battery is new, then normal use will keep it at peak performance.

What is the first limit reached during continuous operation — voltage drop or thermal cutoff?

The cell is rated at 3.7 volts and must not be stored above 60 °C; sustained loads that push temperature toward that limit will trigger protection before voltage sags.

Does the pack generate noticeable heat or noise when powering a medical device all day?

The 8 g lithium-ion pack has no moving parts and runs silently; under typical loads it stays barely warm thanks to the built-in over-voltage and short-circuit safeguards.
