How long does a Li polymer battery last?

Instead of a set time in months, lithium polymer (Li-ion) batteries are rated for charge cycles. This means a full discharge and recharge cycle counts as one unit. Here's a breakdown of how long a Li-ion battery might last:

Charge cycles: A typical Li-ion battery can last for around 300 to 500 charge cycles before its capacity significantly reduces (around 80% of original).

Months: If used daily and charged every day, this translates to roughly 10 to 17 months before noticeable capacity loss.

However, this is just an estimate. The actual lifespan depends on various factors like:

Usage patterns: Frequent deep discharges (letting the battery fully drain) or extreme temperatures can shorten battery life.

Storage: For long-term storage, keeping the battery at around 50% charge and room temperature is ideal.

By following proper charging and storage practices, you can maximize the lifespan of your Li-ion battery.
