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 when a lithium battery is fully discharged?
When lithium batteries are fully discharged, the chemical reactions inside the battery can change, directly affecting its capacity. For example, if a 21700 battery is over-discharged, its usable energy will be significantly reduced, leading to shorter usage time, and it may not be able to fully recharge to its original capacity.
What happens if a lithium battery is not charged?
The damage to the battery's internal components can be so severe that it may no longer hold a charge or even be able to accept a charge. This is why preventing deep discharge is crucial for maintaining the health and lifespan of your lithium-ion batteries. Part 3. How often should a lithium battery be charged when it is not used?
Why do lithium ion batteries lose charge?
The root of the problem lies in the very nature of lithium-ion batteries. Unlike traditional lead-acid batteries, which can withstand prolonged periods of inactivity, lithium-ion batteries have a natural tendency to self-discharge. This means they lose charge even when not in use, a process driven by internal chemical reactions.
Does a lithium battery degrade if not used?
Unfortunately, yes—lithium-ion batteries will still degrade even if not in use. 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?
What is the principle of lithium battery discharge?
The principle of lithium battery discharge is to react with the chemical material wrapped in it. For example, the lithium-ion 21700 battery relies on the flow of lithium ions from the negative electrode to the positive electrode to generate current.
