Summary
As winter approaches, the video creator addresses common questions about maintaining lithium batteries (such as those used in surfboards), emphasizing that proper winter care directly impacts battery lifespan, performance, and safety. [00:00] Key practices include: avoiding sub-zero temperatures for long-term storage, keeping the charge level between 60% and 80%, and topping up the charge every two to three months to prevent damage from over-discharge; if the battery has been used in seawater, it should also be soaked and rinsed with fresh water and thoroughly air-dried. [00:09] Additionally, power on the device periodically to let the motor idle for about 30 seconds, and never start the equipment in freezing conditions. [00:42]
Highlights
- 🔋 Do not store the battery in an environment below zero degrees Celsius for an extended period of time. [00:00]
- 📉 Staying at full charge long-term accelerates chemical aging and causes capacity loss; storage charge level should be kept between 60% and 80%. [00:09]
- ⏰ Check the battery every two to three months, and if it drops below 40%, recharge it back to the storage level. [00:19]
- ⚠️ Avoid letting the battery drain to 0% or staying at 40% without charging for extended periods, otherwise the battery may enter sleep mode, become unable to charge, and get damaged.[00:25]
- 🌊 For equipment used in seawater, soak it in fresh water for 15 minutes to wash off the salt, then put it in a well-ventilated area to dry both inside and outside. [00:34]
- 🌀 Powering off every two to three months and letting the device idle for about 30 seconds can prevent the motor from seizing after prolonged inactivity. [00:42]
- ❄️ Especially after use in seawater, never start it in freezing conditions, as residual water freezing may damage components. [00:51]

Think
- 1. What should the battery level be maintained at during long-term storage?
- Keep it at around 60% to 80%, and check every two to three months. If it drops below 40%, recharge it back to storage level. [00:09]
- 2. How should we handle the device if it has been used in seawater?
- Soak in fresh water for 15 minutes to remove the salt. After rinsing thoroughly, place in a well-ventilated area to allow both the inside and outside to dry completely. [00:34]
- 3. Why can't I start the device in a freezing environment?
- Even a small amount of residual water can damage components after freezing. [00:51]
Glossary of Terms
- **Hibernation level**: The recommended charge range for long-term battery storage, approximately 60% to 80%, which can slow down aging. [00:09]
- **Chemical aging**: When the battery remains fully charged for an extended period or is exposed to extreme environments, internal chemical reactions accelerate, leading to capacity degradation. [00:09]
