If I overcharge my laptop battery, will the life span decrease?
First it’s important to understand what overcharging is:
Over-charging occurs when the charger keeps the battery at a temperature that is warm to touch (body temperature) while in ready condition.
Li-Ion laptop batteries have built-in controller chips which prevent it from overcharging, as they can explode if overcharged. Overcharging does not affect the life span other than potentially destroying the battery.
A lithium-based battery should never be allowed to get warm in a charger. If you have this happen, the battery is no good or the charger is not working properly. Don’t continue to use the battery or charger if this happens.
A Lithium-ion battery may be damaged by extensive overcharging (continuously on a charger for more than 24 hours). Damage to the battery from overcharging would only occur in the very unlikely event of a malfunction of the charging system.
When using a laptop as a desktop replacement the battery should not be left in for long periods of time. The laptop will over time discharge the battery. Remove the battery – making sure that it is charged to 40% and store it in a dry, warm place. Ensure that it is wrapped protectively and nothing will be dropped on it.
The battery should be re-installed every 3-4 weeks and allowed to fully discharge. Leaving a battery in storage for longer than this without using could cause the battery to fully discharge as the circuitry of the battery itself consumes power.
Leaving a battery in a laptop while using an electrical outlet for long periods of time will keep the battery in a constant state of charging up and that will reduce the life cycle of the battery.
Remember that when you have removed the battery from a laptop while using with an electrical outlet – the automatic battery backup is no longer functional. Make sure to plug your laptop into an uninterrupted power source (UPS) not directly into an outlet or surge protector.
Laptop batteries have finite life spans. Whether you use the power cord and remove the battery it will lengthen the life of the battery.
Li-Ion laptop battery lifespan is approximately 1000 charge cycles, or 2-4 years under normal operating conditions.
Keeping the battery in a cool place can prolong its life but not in a period of extended storage. The Li-ion battery should be stored at 40 percent rather than full-charge state.
The battery ages even if not used. For best results, keep the battery cool. In addition, store the battery at a 40 percent charge level. Never fully charge or discharge the battery before storage. The 40 percent charge assures a stable condition even if self-discharge robs some of the battery's energy. Most battery manufacturers store Li-ion batteries at 15°C (59°F) and at 40 percent charge.
Keeping a laptop battery on constant charge is and never using it is not good for the laptop battery.
Run the battery down and recharging it at least once every month.
Making sure your laptop is ready to run at all times and in any location is important for mobile office professionals. Help protect and extend your laptop's battery life with these simple steps
Use the correct recharging procedure for your laptop. Only use the power cord that came with your laptop or an authorized replacement.
Follow correct maintenance for your battery when not in use. Don't leave it in direct sunlight, areas where it will be exposed to extreme temperatures such as car trunks.
Use your laptop's power management features. The system will run at lower processor speeds when enabling power management features and it will go into "sleep" mode faster when inactive.
Buy batteries with internal processors such as Li-Ion batteries.
Non Li-Ion batteries must be fully discharged and then recharged every 2-3 weeks.
If you don't use your laptop for a period of time, you must fully discharge then recharge the battery.
