1. Newly purchased lithium-ion batteries will have some charge. Therefore, users can use them directly when they receive the batteries, use up the remaining charge, and then recharge them. After 2-3 normal uses, the activity of the lithium-ion batteries can be fully activated.
2. Power lithium-ion batteries do not have a memory effect and can be charged whenever needed, but they should not be over-discharged. Start charging when the machine indicates that the battery is low.
3. In daily use, newly charged power lithium-ion batteries need to be left to stand for a period of time until their charging performance stabilizes before use; otherwise, it will affect the battery's performance.
4. When not using the instrument, be sure to remove the batteries and store them in a dry, cool place.
5. The charging temperature of the power lithium-ion battery is 0℃～45℃, and the discharging temperature is -20℃~60℃.
6. Do not store with metal objects, as metal objects may come into contact with the positive and negative terminals of the battery, causing a short circuit, damaging the battery, or even posing a risk.
7. Do not strike, puncture, step on, modify, or expose the battery to sunlight. Do not place the battery in microwave, high-voltage, or other similar environments.
8. When charging the battery, use a standard, compatible lithium-ion battery charger. Do not use inferior or other types of batteries.
Regardless of the reason, some people do hold a common misconception: the fuller the battery, the better. I can tell you with certainty that regardless of the type of battery—ternary lithium, lithium iron phosphate, model, or capacity—overcharging will reduce battery lifespan, decrease discharge performance, and in severe cases, even cause safety accidents. My personal recommendation is to generally not exceed 90% of the battery's total capacity, and in special circumstances, not exceed 95%. Only charge to 100% when verifying battery capacity.
