Is it bad to leave a lithium ion battery dead?

A: YES!! it is bad to fully discharge a lithium ion battery!! In general, it is bad to fully discharge any lithium ion based battery chemistry, but, because MEGALiFe Battery is based on LiFePO4 cells, we will place our focus there. We will also classify ‘fully discharging’ a battery as taking it all the way down to 0v.

Can lithium batteries be fully discharged?

Unlike NiCad batteries, lithium-ion batteries do not have a charge memory. That means deep-discharge cycles are not required. In fact, it’s better for the battery to use partial-discharge cycles. Battery experts suggest that after 30 charges, you should allow lithium-ion batteries to almost completely discharge.

How do I know if my lithium-ion battery is damaged?

There are 5 warning signs that your lithium battery is damaged:

1. The capacity is reduced.
2. The voltage is low.
3. The self-discharge rate is high.
4. The battery is overheating.
5. The battery is bloated.

How long can you leave a lithium battery uncharged?

When a battery has been unused for 6 months, check the charge status and charge or dispose of the battery as appropriate. The typical estimated life of a Lithium-Ion battery is about two to three years or 300 to 500 charge cycles, whichever occurs first.

Does leaving a battery uncharged damage it?

2 Answers. Yes, leaving a lithium ion battery fully discharged for long periods can destroy the cell’s ability to hold a charge. If you are going to be storing batteries for a long time, leave them about half charged.

Do lithium ion batteries discharge when not in use?

Rechargeable Lithium-Ion batteries have a limited life and will gradually lose their capacity to hold a charge. As the battery loses capacity, the length of time it will power the product (run time) decreases. Lithium-Ion batteries continue to slowly discharge (self-discharge) when not in use or while in storage.
