18650 7.2V 7.8Ah lithium-ion battery features:

  • It adopts A-class 18650 cells from domestic first-line lithium battery manufacturers, with a capacity of more than 2600MAH, no false standard, and long working hours.
  • 18650 batteries are matched for very good consistency, high discharge plateau and long lifespan.
  • Equipped with a 7.2V lithium battery protection board to prevent overcharge and overdischarge, maximize the protection of the battery, and ensure safety performance.
  • The battery cover, leads and plugs are all top quality accessories and the entire battery pack is well made.

18650 li-ion battery usage tips:

  • The battery needs to be removed when the loudspeaker or other equipment will not be used for a long time.
  • The battery is suitable for storage when it is charged. The storage time is more than three months. It is best to charge the battery in time before storing it, which can prolong the battery life and effectively prevent the irreversible attenuation of the battery capacity.
  • When the 18650 battery is over-discharged: as long as the charger is plugged in, the protection can be unlocked.
  • When the 7.2V lithium-ion battery is overcharged, the protection can be released as long as it is connected to the machine and started to use.
  • When the battery is over-current or short-circuit protected: the load can be removed and the protection can be released.
  • When measuring the battery voltage with a multimeter, it is 0, please confirm that there are point no 3 or 4 protections, and then it can be confirmed that the battery is faulty.

Correct maintenance method of 18650 lithium battery:

  • The temperature is suitable, anti-cold and heat. The best use ambient temperature is about 25°C, because the ambient temperature is too high, the battery will be overcharged and gas is generated, and the ambient temperature is too low, the battery is undercharged.
  • In the correct use of 18650 lithium battery, the charging method of lithium battery is the most important, because incorrect charging method will cause safety problems, and discharge and daily maintenance only affect the service life of lithium battery, lithium battery itself is also a This kind of consumables, no matter what we do, we can’t avoid its final wear and tear, but we use the correct method to delay its aging.
  • If you want to maximize the performance of lithium-ion batteries, you need to use it frequently, so that the electrons in the lithium battery are always in a state of flow. If you do not use the lithium battery often, please remember to complete a charging cycle for the lithium battery every month and do a power calibration, that is, deep discharge and deep charging.
  • Pay attention to the charging voltage. If the charging voltage is too high, the battery will be overcharged, otherwise, the phenomenon of insufficient charging will occur, which is a need to pay attention to the damage to the 18650 lithium battery.
