How to Charge Lithium Ion Battery

Devices like laptops, smartphones, and tablets all have lithium-ion batteries. Properly charging and taking care of these means that you can preserve the battery’s health and help it to last for as long as possible. To charge your device , check the battery level, plug it into a charger, and disconnect it when the charge is below 100%. Take simple measures to preserve your lithium-ion battery such as practicing shallow discharge, not letting it continuously charge, and storing it at the correct temperature.

If you want to know more about how to charge lithium ion battery. Please follow us. The charging method of lithium battery is limited voltage and constant current, which is controlled by IC chip. The typical charging method is: first detect the voltage of the battery to be charged, if the voltage is lower than 3V, pre-charge first, and the charging current is set 1/10 of the current, after the voltage rises to 3V, it enters the standard charging process.

The constant voltage charging starts when the battery voltage rises to 4.2V. During this time, the constant current charging ends. According to the saturation of lithium-ion batteries, the charging current decreases gradually as the charging process continues. When the current drops to 0.01c, the current charging is considered to be ended. (The nominal capacity of the battery to the current is expressed by C, for example, the battery capacity is 100mAh, and the charging current of 100mA is 1C.)

Whenever lithium-ion batteries have to be kept in the charger for functional ability, some chargers implement a short filling charge to pay for the little self-discharge the battery and its shielding circuit take in. The charger might get started once the open-circuit voltage falls to 4.05V/cell and switches off yet again at 4.20V/cell.

About Lithium Ion Battery

  • Deep Cycle Battery: Maxworld LiFePO4 battery provides 2000+ cycles compared to 300~500 cycles in a lead-acid battery. The service life of LiFePO4 batteries is 8 to 10 times longer than standard lead-acid batteries. The weight of the lithium iron phosphate battery is 30% lighter than the lead-acid battery of the same capacity.
  • Lithium Iron Technology: Maxworld deep cycle lithium-ion battery has higher energy density, more stable performance and greater power. LiFepo4 battery will not burn when overcharged, over-discharged, overcurrent, or short circuit, and can withstand high temperatures without decomposition. It can support fast charging and solar panel charging. Our LiFepo4 battery is a green battery, it does not contain any heavy metals and rare metals and is more environmentally friendly.
  • Built-In BMS & Convenience & Maintenance Free: Maxworld LiFePO4 battery has built-in BMS (Battery Management System) to protect it from overcharge, over-discharge, over-current, and short circuit with an excellent self-discharge rate. Built-in high temp cut-off prevents charging over 122 °F (50 °C). Plus, Li-Ion batteries can be safer than Lead Acid batteries, which have no protection against ground faults. This product fits for outdoor camping power and indoor easy installation.
  • Widely Used: Maxworld lithium iron phosphate battery can be used in the following areas: home energy storage system, UPS backup, lighting, digital/CCTV cameras, portable TV, e-Robot, electric vehicles, DIY loudspeaker, 12V router, air pump, fish finder, golf car, trolling motor, motorhome/RV & camper, Houseboat, Travel Trailer, Dump Trailer and more. When the batteries are used in parallel or series, the battery voltage and capacity must be the same and purchased in the near time(within 6 months).
