Why do batteries lose capacity?
Hold onto your hats, folks, because the way you use your battery matters! High charge and discharge rates, keeping a battery at maximum capacity for extended periods, and frequent shallow discharging – these are all culprits that speed up capacity loss. Don’t underestimate the impact of Mother Nature on battery capacity!
Why is lithium battery capacity loss important?
Once the theoretical cycle number is exceeded, the capacity of the battery will have a very significant decline, and this time it is time to replace the battery. Therefore, lithium battery capacity loss is very important, especially the irreversible battery capacity loss, which is related to the battery life.
How to reduce battery capacity loss & prolong battery life?
There are ways to mitigate battery capacity loss and prolong the life of your batteries: Avoid Extreme Temperatures: Keep your devices at room temperature as much as possible. That means no leaving your smartphone in a hot car in summer! Implement Proper Charging Practices: Try not to charge your battery to 100% all the time.
Why does battery capacity fade?
In most cases, the decrease is linear and capacity fade is mostly a function of cycle count and age. A deep discharge stresses the battery more than a partial discharge. It is therefore better not to discharge the battery fully but charge it more often.
How does battery capacity work?
Battery capacity works in a similar fashion – if we stretch our imagination. A cell starts accumulating ‘sediment’ over time, to continue this analogy. Charge time speeds up because there is less space to fill. Although the amount of available energy (capacity) reduces. There are several reasons for this capacity loss.
When should you replace a lithium ion battery?
