What is the lifespan of rechargeable batteries?

Rechargeable batteries have a limited lifespan and gradually lose capacity over time. As batteries age, they may discharge faster and can also self-discharge more quickly when not in use.

Battery lifespan depends on factors such as:

• Battery chemistry
• Number of charge and discharge cycles
• Depth of discharge
• Charging method
• Operating conditions and temperature

Typical lifespan by battery type

• NiMH batteries: approximately 500 charge cycles under normal use
• Li-ion and LiPo batteries: approximately 400 cycles or around 3 years of average use
• LiFePO4 batteries: typically between 2,000 and 5,000 cycles and often 5 to 10 years of service life

Frequent deep discharge or operating batteries continuously at maximum performance can significantly shorten lifespan.

To maximize battery life:

• Use the correct charger
• Avoid deep discharge where possible
• Store batteries properly
• Avoid excessive heat and overcharging

LiFePO4 batteries are especially known for their exceptionally long lifespan and high cycle stability.
