Acer L850GL User Manual

The useful lifespan of a battery is adversely affected by the following 
behavior:
• Constantly charging the battery/device when already at full capacity.
• Charging the battery/device at temperatures above 35 °C (95 °F) or 

below 0 °C (32 °F).

To prevent damage, follow these precautions:
• Stop charging the battery once it reaches 100% capacity; regularly 

or frequently charging a fully charged battery for an extended period 
of time may cause battery deformation or damage. We recommend 
that you recharge the device when the battery level drops below 
70% capacity.

• Do not charge battery in temperatures above 35 °C (95 °F) or below  

0 °C (32 °F).  Charging in abnormally high or abnormally low 
temperatures can cause battery deformation or damage.

• The charging port must be clean and free from debris and should 

only be used with Acer charging equipment. Use of a non-Acer 
battery or charging equipment can cause damage to the product 
and will void the warranty.

• If you plan to store the device for a long period of time, turn-off the 

device, remove AC power and store the product at room 
temperature  (0 °C - 35 °C) in a dry (humidity: 45% - 80%), well-
ventilated area. Avoid direct sunlight, high temperatures and high 
humidity. Do not leave your device’s battery completely discharged 
for a long period of time; this may cause battery deformation or 
damage. We recommend that the battery is checked and charged to 
approximately 50% capacity every 6 months.

When using a charging cart or a small space to simultaneously charge 
or operate multiple devices , the area must be well- ventilated and the 
temperature kept between 0 °C (32 °F) to 35 °C (95 °F) and battery 
charging must be stopped when 100% capacity is reached.  
Continuous charging can cause deformation or damage to the battery/
device.
