Lithium battery pack capacity error

What are common problems with lithium-ion batteries?

These common issues with lithium batteries can disrupt our daily routines, compromise our safety, and decrease the lifespan of our beloved gadgets. Identifying common problems with lithium-ion batteries is key to preventing mishaps and ensuring your devices function efficiently. One frequent lithium-ion battery problem is rapid discharge.

What causes a lithium battery to fail?

Root cause 2: Too long storage time. Lithium batteries are stored for too long, resulting in excessive capacity loss, internal passivation, and increased internal resistance. Solution: It can be solved by charging and discharging activation. Root cause 3: Abnormal heat.

What causes low voltage in a lithium battery?

Root cause 1: High self-discharge, which causes low voltage. Solution: Charge the bare lithium battery directly using the charger with over-voltage protection, but do not use universal charge. It could be quite dangerous. Root cause 2: Uneven current.

What causes a bad battery pack?

It might not be your device that's the problem but the battery pack itself. Specifically, a bad cell or two inside the pack could be causing the issue. Don’t worry—finding and diagnosing bad cells in a battery pack is simpler than it sounds.

How to charge a bare lithium battery?

Solution: Charge the bare lithium battery directly using the charger with over-voltage protection, but do not use universal charge. It could be quite dangerous. Root cause 2: Uneven current. Due to contact resistance or detection of charge, the current is inconsistent caused by the uneven charge of the cell.

What happens if you overcharge a lithium battery?

When charging lithium battery, it will naturally expand, but generally not more than 0.1 mm. However, overcharging will cause electrolyte decomposition, increase internal pressure, and finally lithium batteries expansion. Solution: Don’t overcharge, especially don’t charge for more than 12 hours at a time.
