What happens if you don't use a lithium battery?

Capacity Loss: Over time, unused lithium batteries can lose their ability to hold a charge. This means that when you finally decide to use the battery, it might not last as long as it would have if it had been used regularly. The passivation layer that forms on the electrodes can contribute to this loss of capacity.

Why does a lithium ion battery lose power?

Since voltage also drops as the battery discharges, the increased resistance causes it to reach cutoff voltage earlier and so reduces its effective capacity. An old lithium-ion battery which is not powerful enough to run the device it was designed for may still be useful in a lower current application.

What causes a lithium ion battery to fail?

The excessive current flow into the lithium-ion cell causes overheating and lithium plating, which leads to battery failure. When the current is in excess, the excessive joules will initiate more heat into the cell, causing overheating. The overheating leads to increased cell temperature hence failure.

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.

Is your lithium ion battery dead?

When your lithium ion battery appears to be at the end of its life there is a temptation to view it as completely dead, but in reality units often still have power in them – just not enough to power the device they were intended for.

What happens if a lithium battery degrades?

This is called calendar aging, where the battery degrades as a function of time. Calendar aging is unavoidable because the degradation occurs even when there is zero battery usage. What happens when a lithium battery degrades? When a lithium battery degrades, end users will notice lower capacity and reduced power capability.
