Carefully remove the battery from the device. Wear protective gloves (nitrile or rubber) to shield your skin from potential chemical residue.
A cracked exterior often means internal layers have shifted. This shifting can cause the positive and negative internal terminals to touch, generating an immediate electrical short and intense heat.
Battery swelling occurs when gas builds up inside the battery case due to internal pressure. The causes of this pressure vary between lithium and lead-acid batteries.
Once atmospheric oxygen breaches the sealed container, the internal lead-calcium plate grids oxidize. This destroys the battery's chemical capacity and lowers its Cold Cranking Amps (CCA). ytstc01 battery cracked
Using a fishbone (Ishikawa) diagram + material analysis, the following primary causes were identified:
Searching for is often the first sign that your power tool battery is nearing its end. While a small, non-swollen, cosmetic crack might be temporarily taped for a single day’s work, the safe and smart long-term solution is immediate replacement.
Is there any building up around the crack? Share public link Carefully remove the battery from the device
Finding a crack in a device battery is a serious issue that requires immediate attention. If you are dealing with a situation, you must prioritize safety over functionality. This specific battery model is commonly used in specialized electronics, testing equipment, and specific consumer devices. A physical breach of its casing compromises the chemical stability inside.

This is a Lithium-polymer (Li-polymer) battery. Its specifications are: This shifting can cause the positive and negative
When installing a new battery, always disconnect the negative (black) terminal first and reconnect it last to avoid short-circuiting against the frame or casing.
Place the cracked battery inside a sealed, non-conductive container (like a plastic zip bag) or wrap its terminal contacts in electrical tape before transport.
