The correct charging method for ternary lithium-ion batteries
1. After fully charging the ternary lithium-ion battery with the matching charger, charge it for one hour.
2. Discharge the battery until it is about 20% full, then recharge it. Over-discharging will damage the ternary lithium-ion battery.
3. When charging ternary lithium batteries, try to fully charge them in one go.
4. Do not completely drain the battery; always leave 20% or more of charge remaining. This is extremely beneficial for battery life, comparable to that of lithium iron ion batteries.
5. It's okay to use the battery out occasionally, but you should recharge it as soon as possible. If you don't have enough time, you don't have to fully charge it, but don't leave it uncharged for a long time, as this will also shorten its lifespan.
The lifespan of a lithium battery is generally 300-500 charging cycles. Assuming a complete discharge provides 1Q of electricity, and disregarding the reduction in capacity after each charging cycle, a lithium battery can supply or replenish a total of 300Q-500Q of electricity over its lifespan. Therefore, if you charge after using half the battery capacity each time, it can be charged 600-1000 times; if you charge after using one-third of the battery capacity each time, it can be charged 900-1500 times. And so on. If you charge randomly, the number of charges is uncertain. In short, regardless of how you charge, the total amount of electricity replenished is constant at 300Q-500Q. Therefore, we can also understand it this way: the lifespan of a lithium-ion battery is related to the total amount of electricity it can be charged, not the number of charging cycles.
