Lenovo Tablet Charging Tips

Avoid extreme ambient temperatures and other tips for how to charge tablet battery safely

Avoid extreme ambient temperatures and other tips for how to charge tablet battery safely

Lenovo is designed to deliver an experience that is simple and easy to use. This is only possible through a combination of advanced technologies and sophisticated engineering. One important technology area is battery and performance. Batteries are complex technology, and a number of variables contribute to battery performance and related tablets. All rechargeable batteries are consumables and have a limited lifespan with capacity and performance that will eventually decline. This loss of capacity (aging) is irreversible.

In general, Lithium-ion/Polymer batteries will continue to discharge slowly (self-discharge) when not in use or when in storage, so it is essential to periodically check the battery’s capacity status.

A battery lifespan varies based on temperature, charge and discharge cycle, manufacturing cycle, frequency and method of using. Therefore, we recommend:

1. Avoid extreme ambient temperatures:

Lenovo Tablet product is designed to perform well in a wide range of ambient temperatures, with 16℃ to 30℃ as ideal comfort zone. It is especially important to avoid using or charging device at ambient temperatures higher than 35℃, which can permanently damage battery capacity.
When using Tablet in a very cold environment, you may notice a decrease in battery life, but this condition is temporary. Once the battery’s temperature returns to its normal operating range, its performance will return to normal as well. It is especially important to avoid charging device in a low temperature, which can permanently damage battery performance and capacity.

2. Avoid overcharging the device:

The device is designed to stop the battery from charging after it’s full. However, keeping the tablet constantly plugged all the time (7/24), it may permanently damage battery performance and capacity, and potentially cause damage to other parts of the product.

3. When device is stored for an extended period of time, a regular check of the battery capacity is required. If the tablet is not used for a long time, two key factors will affect the overall health of the battery: the environmental temperature and the percentage of charge on the battery when it’s powered down for storage. Therefore, we recommend the following:

  • Do not overcharge or fully discharge the device’s battery for storage. If a device is stored with its battery fully discharge, the battery could fall into a deep discharge state, which renders it incapable of holding a charge, and may cause permanent damage to the battery and further damage to the product when charging.
  • If a device is stored with its battery fully charged for an extended period of time, the battery may lose some capacity, leading to a shorter battery life.
  • Power off the tablet to avoid unnecessary battery use.
  • Place the tablet in a cool and moisture-free environment at32℃ or less.
  • Recharge the Tablet to 40%-60% capacity every six months.

4. Lenovo adapters and cables are strictly tested to ensure its proper function, performance and safety. However, non-Lenovo adapters and cables are also found in the market with claims of compatibility with Lenovo Tablet. Lenovo cannot verify these claims and its safety when used with Lenovo tablets.

  • Customers are strongly recommended to use the tablet’s original adapter and cable to charge Lenovo Tablet.
  • If use some centralized charging devices to charge multiple Lenovo products, make sure the charging specifications of the charging devices is compatible with Lenovo tablet products.
  • The centralized charging device itself needs to have a good heat dissipation function. During the whole process of using, be sure to maintain good ventilation around the centralized charging device to ensure the internal temperature of the centralized charging device does not exceed 35℃ during the charging process.
  • Charging a product when it is inside certain styles of cases may generate excess heat, which can affect battery capacity. If the device gets hot when being charged, take it out of its case first.
  • When using a centralized charging device to charge multiple products at the same time, be sure to turn off the products to avoid heat accumulation during the charging process, which may affect the battery’s capacity and performance.

5. If experiencing swollen battery cover*, LCD crack, or product abnormal phenomenon such as overheat, burnt smell, during use or when charging, immediately stop using or charging the product, and place it in a relatively open and ventilated area (away from any flammable items). Then contact the Lenovo designated authorized repair station for solution, including testing and maintenance.

6. Maintenance personnel from Lenovo designated and authorized maintenance sites, maintenance personnel are professionally trained to perform maintenance to relevant products. We strongly suggest customer to contact designated and authorized maintenance site of Lenovo for testing and repair if experiencing problems when using Lenovo tablet products.

*Lenovo tablet products use Lithium-ion polymer batteries. Swollen battery does not belong to safety issues. It is a universal issue from Lithium-ion Polymer cell technology and is industry-wide affecting all companies: Lenovo Battery Technology - Best Practices Guide
