It's a common misconception that lithium batteries don't last as long as other types of batteries. In fact, if properly cared for, a lithium battery can last up to 20 years! Here are a few tips to help you get the most out of your lithium battery:
1. Avoid extreme temperatures. Lithium batteries perform best when they're kept at moderate temperatures - too hot or too cold can shorten their lifespan.
2. Store them partially charged. It's actually better for lithium batteries to be stored at around 50% charge than 100% charge. This helps to prevent degradation and prolongs the life of the battery.
3. Use them regularly. Like all batteries, lithium batteries will degrade faster if they're left unused for extended periods of time. So, if you have a spare battery that you're not using, make sure to give it a charge and use it every few months to keep it in good condition.
4. Keep an eye on the voltage. Once a lithium battery starts dropping below 3 volts per cell (about 2/3 full), it's time to recharge it - letting it drop any lower will damage the battery and shorten its lifespan significantly.
