How To Maximize the Lifespan of Your Lithium-Ion Batteries
Lithium-ion batteries have become the preferred choice for modern tools and appliances, offering superior performance and a longer lifespan compared to older NiMH battery types. However, like all batteries, proper care is essential to ensure they perform at their best and last as long as possible. This is especially important for clippers with an in-built battery which cannot be replaced independently, as the battery’s health directly impacts the lifespan of the tool itself.
How to Charge Lithium-Ion Batteries
Unlike older NiMH batteries, which required a full discharge and recharge to maintain battery health, lithium-ion batteries are better off with partial discharges. Using 20% to 80% of the battery’s capacity before recharging is ideal for extending its life.
Leaving the battery fully charged all the time can actually shorten its overall lifespan, and performing a deep discharge can damage it. It’s best to unplug the device once it’s sufficiently charged—just below 100%. However, it’s still beneficial to perform a full charge and discharge every 30 cycles or so to recalibrate the battery.
Why Temperature is Important
Lithium-ion batteries thrive in a controlled temperature range of 20-25°C. Avoid exposing your battery to extreme heat or cold, as these conditions can significantly reduce its lifespan.
Refrain from charging your appliance when temperatures fall below freezing (0°C), and try to limit the usage of your tool to prevent overheating. While lithium-ion batteries don’t heat up as much as other types, heat remains one of the primary factors that can degrade the battery over time. Never leave your device in direct sunlight, or in a hot environment like a car on a summer day, as excessive heat can cause irreversible damage.
Spare Batteries: Do They Really Help?
While spare batteries might seem like a good idea, they don’t necessarily last longer than the battery in use. Over time, all batteries degrade, and even those kept in storage won’t last forever. Lithium-ion batteries age naturally, whether they’re being actively used or not.
How Long Can a Lithium-Ion Battery Last?
The lifespan of a lithium-ion battery depends largely on how well it’s cared for. With proper maintenance, a high-quality lithium-ion battery can last anywhere from 300 to 500 charge cycles. However, factors such as excessive heat, heavy usage, and improper charging can significantly reduce this lifespan.
Full discharges, frequent overheating, and exposure to high temperatures (above 30°C) are particularly damaging to the battery’s long-term health. On average, a lithium-ion battery can last 2-3 years with regular use. Batteries in storage, even if unused, will lose about 20% of their capacity annually. If stored in ideal conditions, a battery may retain its capacity for up to 3-4 years.
By following these simple care tips, you can ensure that your lithium-ion batteries perform at their peak for as long as possible. Remember: A little attention goes a long way in maximizing battery life.
