6 Frequently Asked Questions about “Lithium battery pack loses power quickly when left stationary”

Do lithium ion batteries degrade over time?

Lithium-ion batteries unavoidably degrade over time, beginning from the very first charge and continuing thereafter. However, while lithium-ion battery degradation is unavoidable, it is not unalterable. Rather, the rate at which lithium-ion batteries degrade during each cycle can vary significantly depending on the operating conditions.

What happens if a lithium battery is left unused?

If left unused for months, a fully charged lithium battery can become completely depleted. 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.

Do lithium batteries drain when not in use?

Yes, lithium batteries do drain when not in use, thanks to self-discharge. The rate of self-discharge depends on the battery's quality, age, and storage conditions. On average, lithium batteries lose about 2-3% of their charge per month when stored properly.

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.

What happens if a lithium battery is left in a deep discharge?

If a lithium battery is left in a discharged state for too long, it can fall into a deep discharge state. In this state, the battery's voltage drops too low, which can lead to irreversible damage and a significant reduction in capacity. To avoid this, always ensure that lithium batteries are stored with a partial charge. Risks of Deep Discharge

Why do lithium-ion batteries get rated based on cycling based degradation?

Since this is a known phenomenon, many lithium-ion battery manufacturers will give their batteries a rating according to their cycling-based degradation. For example, a battery may be rated as being able to complete 1,000 full cycles before it degrades from full capacity to 80% capacity.
