Use only LG-approved chargers specific to your phone model since they are designed to maximize battery life.

Do not disassemble or short-circuit the battery.

Keep the battery’s metal contacts clean.

Replace the battery when it no longer provides acceptable performance. The battery can be recharged several hundred times before replacement.

Recharge the battery after long periods of non-use to maximize battery life.

Battery life will vary due to usage patterns and environmental conditions.

Use of extended backlighting, Browser, and data connectivity kits affect battery life and talk/standby times.

The self-protection function of the battery cuts the power of the phone when its operation is in an abnormal state. In this case, remove the battery from the phone, reinstall it, and turn the phone on.

Explosion, Shock, and Fire Hazards

Do not put your phone in a place subject to excessive dust and keep the minimum required distance between the power cord and heat sources.

Unplug the power cord prior to cleaning your phone, and clean the power plug pin when it’s dirty.

When using the power plug, ensure that it’s firmly connected. If not, it may cause excessive heat or fire.

If you put your phone in a pocket or bag without covering the receptacle of the phone (power plug pin), metallic articles (such as a coin, paperclip or pen) may short-circuit the phone. Always cover the receptacle when not in use.

Don’t short-circuit the battery. Metallic articles such as a coin, paperclip or pen in your pocket or bag may short-circuit the + and – terminals of the battery (metal strips on the battery) upon moving. Short-circuit of the terminal may damage the battery and cause an explosion.

Do not disassemble or crush the battery. It may cause a fire.

General Notice

Using a damaged battery or placing a battery in your mouth may cause serious injury.
