The actual life of a laptop battery will vary with computer usage habits. For most users, it is not uncommon to experience differences in battery life, of anywhere from just under one hour to over two hours in each sitting. If you are experiencing shorter battery life cycles, say 10 to 15 minutes, it may not yet be time to order that new battery.

There are several factors to take into consideration when determining if the time has come to replace your battery. This information may also apply to that new battery that you have recently purchased, that has been giving you fits. The two primary things to consider when troubleshooting battery problems is Usage Habits and Battery Memory. We will cover both in their complexities in just a moment, but first, let us take a look at what you should expect from your battery’s life cycle.

NiMH batteries usually last 1.5 to 2.5 hours.
LiION batteries usually last 2.0 to 3.0 hours.

These are average results and the results will vary greatly depending on your system’s conservation settings, the temperature of the room and the climate that you are operating your computer in. As a general rule, your Lithium Ion battery will last much longer than your standard Nickel Metal Hydride battery.

A)   A new battery usually comes in a discharged condition and with a very low capacity. It is generally recommended to fully charge laptop battery before use. .Refer to the user guide of your electronic device for charging instructions.

B)   A new battery pack needs to be circulated (fully discharged and recharged ) three to five times to reach its optimum performance .

C)   Rechargeable battery will undergo self-discharging when left unused. It should always be stored in a fully charged status and kept in a cool, dry and clean place.

D)   To maintain the optimum performance of a battery pack, it is highly recommended to fully discharge and recharge it at least once a month.

E)   It is normal if a battery gets warm when being charged or used . However , please pay high attention when the battery pack becomes excessively hot. This may indicate a problem with the charging circuit of your electronic device. Ti it necessary to have it checked by qualified technicians when thin occurs.

F)   New battery is sometimes hard to be charged. Your electronic device may indicate a fully charged condition for about 10 to 15 minutes when the new battery pack is being charged for the first times . when this happens , remove the battery pack and let it cool down for awhile. Repeat the charging procedure again. When a new battery is unable to charge ,it is suggested to remove the battery from the device and reinsert it.

• Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns.




• Batteries with fuel gauge (laptops) should be calibrated by applying a deliberate full discharge once every 30 charges. Running the pack down in the equipment does this. If ignored, the fuel gauge will become increasingly less accurate and in some cases cut off the device prematurely.
• Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level.
• Consider removing the battery from a laptop when running on fixed power. (Some laptop manufacturers are concerned about dust and moisture accumulating inside the battery casing.)
• Avoid purchasing spare lithium-ion batteries for later use. Observe manufacturing dates. Do not buy old stock, even if sold at clearance prices.
• If you have a spare lithium-ion battery, use one to the fullest and keep the other cool by placing it in the refrigerator. Do not freeze the battery. For best results, store the laptop battery at 40% state-of-charge.

A)   do not modify or disassemble under any circumstances.

B)   Avoid placing the battery under high temperature or next to heat-sensitive materials.

C)   Do not immerse in or expose to water.

D)   Do not leave the battery in your device if it is not being used for a period of time

E)   Do not short circuit or store the battery with metal objects such as necklaces and hairpins.

F)   Do not hit or misuse the battery . Batteries may leak or explode if improperly handled.

G)   Discontinue use immediately should you notice any leakage or deformation

H)  Do not imply any pressure on the battery or it may cause damage to it and may affect the performance of the battery
