冬天锂电池应该保持足电状态，这样可延长电池寿命。电池应充满电后再使用。

Lithium batteries should be kept fully charged in winter, which can extend battery life. And the battery should be fully charged before use.

冬季锂电池的充电时间要短，不要超过普通充电时间的1.5倍，可以尽量保持在2小时以内，尽量避免长时间充电，以防止锂电池过热。

The charging time of lithium battery in winter should be short, not more than 1.5 times the ordinary charging time, and it can be kept within 2 hours as far as possible to avoid charging for a long time to prevent the lithium battery from overheating.

冬季锂电池的充电电压要低，不要超过额定电压的1.1倍，并且可以适当降低充电电压，以降低充电温度，保护电池的安全性。

The charging voltage of lithium battery should be lower in winter, not exceeding 1.1 times the rated voltage, and the charging voltage can be appropriately reduced to reduce the charging temperature and protect the safety of the battery.

冬天充电时，尽量将锂电池充电温度调节到适宜范围, 避免电池因冷热影响而无法充电。

When charging in winter, try to adjust the charging temperature of the lithium battery to the appropriate range to avoid the battery being unable to charge due to the influence of cold and heat.

冬天充电时，最好使用专用的锂电池充电器，并且充电时要定期检查电池的温度，以确保充电安全性。

When charging in winter, it is best to use a dedicated lithium battery charger, and regularly check the temperature of the battery when charging to ensure charging safety.

冬天充电时，请勿将电池放置在靠近暖气片、暖炉等发热源的位置，以免影响电池的充电效果。

When charging in winter, do not place the battery near the radiator, heater and other heating sources, so as not to affect the charging effect of the battery.
