General Safety Information for Batteries
Never attempt to open or service any battery. Do not crush, puncture, or incinerate batteries or short circuit the metal contacts. Do not expose the battery to water or other liquids.
Battery abuse or mishandling can cause the battery to overheat, which can cause gasses or flame to “vent” from the battery pack. If your battery is damaged or if you notice any discharge from your battery or buildup from foreign materials the battery leads, stop using the battery and obtain a replacement.
Batteries can degrade when they are left unused for long periods of time. For some rechargeable batteries, leaving a battery unless in a discharged state could increase the risk of a battery short circuit, which could shorten the life of the battery can also pose sate hazard. Do not let rechargeable lithium-ion batters completely discharge or store these batteries discharged state.
Storing your Battery
- Do not store batteries for long periods plugged into or attached to any power source. This includes AC adapters and laptop security carts plugged into an outlet.
- Laptop batteries, including those stored in laptop systems, should maintain an Operational Storage Temperature of 0° to 35°C (32° to 95°F).
- Batteries may be stored in the laptop or outside of the laptop.
- Charge batteries before storing. The recommended charging time should not exceed 1 hour. Typically, this should charge the battery to between 80% and 100%. (Some discharge will take place over time. Stored batteries are expected to discharge 10-15% over a four month period, for your information.)
Tips to make your battery last
- Choose the right battery. Under the same use conditions, a lower capacity battery will wear out faster than a higher capacity battery because it has to be charged more often.
- Use the notebook's power saving controls to reduce battery use in your normal day. For example, turn the Bluetooth off if it is not needed; reduce the screen brightness when conditions permit.
- Avoid exposure to extreme temperatures. If the system is exposed to extreme cold or hot temperatures, allow it to warm up/cool down before use and before charging.
- Contrary to last decades' batteries, modern lithium ion batteries do not need to be fully discharged to maintain health.
- All batteries wear with use and time. When you find the runtime is no longer satisfactory, it may be time to purchase a new battery.
