Mastering basic common sense about using lithium batteries and using lithium batteries wisely can help you have more fun, worry less, and save money.
1. Charging: Be sure to use standard, high-quality batteries. special lithium batteries The charger is used for charging. It has constant current and constant voltage function. The constant current cannot exceed 1C and the constant voltage cannot exceed 4.2V/cell. If conditions permit, it is recommended to charge with a current of 1 C. about 0.5 C.
For the battery Be sure to pay attention to safety when charging, stay at the away from flammable objects and work nearby when charging if you must leave for a long period of time (beyond full charge). time), you can stop charging first and then charge again. The batterieslithium batteries have no memory and can be used at any time. Storage: Do not store them fully charged for a long time otherwise. it can easily cause swelling after long-term storage and affect discharge performance. The optimal storage voltage is 3.8 V to 3.95 V for a single chip. Fully charging before use can effectively avoid battery swelling. For batteries that have not been used for a long time, charge with a low current first to activate it, then discharge it with a low current to set the battery to the best condition. If left for more than 3 months, it is recommended to do so. Check the battery voltage regularly. If the voltage is lower than the optimal voltage, recharging is recommended.
3. Discharge: Electric type lithium batteries cannot be discharged beyond discharge number Cmaximum designed. -Discharging will seriously affect the performance of the battery or directly cause damage to the battery. The possibility of repairing the lithium battery after damage is very low. During use, do not overdischarge. For 11.1 V batteries, the no-load voltage is preferably higher. 10.8 V. For 7.4 V batteries, the no-load voltage is higher than 7.2 V. The standard cannot be 2.8 V/cell. It's different working voltage and no-load voltage, each player can do their own simulations and sum. experience. If you can't confirm, you can use the battery monitor to test during playback.
4. When the battery surface temperature is above 60 degrees, please suspend use and wait for the battery to use it. again when the temperature drops, or choose a battery with better performance, capacity, modeland specifications. Once the battery swells or leaks, it is recommended to stop using it. Do not use sharp metal objects to penetrate it to deflate it. cause an internal short circuit in the battery. The battery explodes or burns.
Smartphones use lithium batteries. Lithium batteries do not have a memory effect, so when a new cell phone is used for the first time, there is no need to activate it several times by charging and discharging it, just load it as you go.
If you use a Huawei mobile phone, please pay attention to the following points during daily use to protect the mobile phone battery and prolong its service life:
1. Official standard charger for battery charging ensures that the charging voltage is stable and meets standards to avoid affecting battery usage.
2. In theorie, keeping the battery power in an average range (e.g. 30% to 80%) is more conducive to extending battery life. Therefore:
(1) After. the mobile phone is fully charged. It is recommended to unplug the charger to avoid charging for a long time or being in a high power state for a long time to accelerate battery aging and prolong battery life.
(2) If the mobile phone is idle for a long time, it is recommended to turn it off and recharge it regularly to maintain about 50% power. If your mobile phone is not used or charged for a long time, the battery may trigger over-discharge protection, resulting in abnormal charging or charging failure.
3. If the temperature is too high or too low, it will affect battery lifeof the cell phone. Therefore:
(1) Please try to avoid using it. environments with low or high temperatures or large temperature differences.
(2) It is recommended to avoid charging and using it for a long time, especially in high-power operating scenarios (such as watching videos, playing large games , etc.). discharging will accelerate the aging of the battery.
