When you get a new laptop or new laptop battery, proper charging, discharging, usage and storage will allow you to maximize your battery's life and capabilities. Before even powering up your laptop for the first time, it is important to know just how to charge and care for your battery in order to get the most out it for as long as you can.

1. Charge & Discharge
   According to CNET authors Asher Moses and Brian Nadel, the first thing you should do with your new laptop is ''let the battery completely drain(5%) before you recharge it''. Letting the battery completely drain(5%) by using it without AC power, and then recharging it to 100 percent before using it again, helps to establish memory within the battery regarding how much of a charge can be held. Do this for at least the first two times when using your laptop on battery power, and repeat as often as you can to get the most out of your battery.
2. Storage
   If you plan to use your laptop as a desktop most of the time, Rick Broida of "PC World" suggests you take the battery out of your laptop and use only AC power. Only put the battery in and charge it whenever you plan on moving the laptop and using it without AC power, because ''if you leave your laptop plugged in 24/7... the battery rarely (if ever) gets a chance to discharge, [so] it loses its capacity to hold a charge''. Charge the battery before moving your laptop, and discharge it completely before recharging again, if you can.
3. Temperature & Climate
   One of the main causes of battery failure is overheating. "PC Magazine's" Erik Rhey suggests that you can avoid overheating by using cooling pads and not placing your laptop on soft surfaces like pillows and blankets. Some batteries are actually designed to sense if they are getting too warm and simply will not charge if they are, so it is in your interest to keep your battery cool. Dust getting into the laptop and clogging the cooling fan can also cause overheating problems, so try to keep the area around your laptop clean. Of course, leaving your laptop in your car where it can become excessively hot can also cause problems, so avoid that as well.
4. Power Settings
   Once you have gotten the hang of charging your batteries, visit your computer's Power Settings in the Control Panel and dim your computer's display, adjust the timeout settings for your display to turn off and for your laptop to sleep, and see if any advanced settings can be changed to really extend your battery life as far as you can.

When replacing your laptop battery, you should always choose a battery with the same voltage as your original. There are however a couple of exceptions to this rule;

1. 7.2V batteries and 7.4V batteries are interchangeable, they are in common use.

2. 10.8V batteries and 11.1V batteries are interchangeable, they are in common use.

3. 14.4V batteries and 14.8V batteries are interchangeable, they are in common use.

4. 10.8V(=11.1V) batteries and 14.4V(14.8V) batteries are not interchangeable, they are not compatible.

If in doubt, please feel free to give us a call or drop us an email. Using a battery with an incorrect voltage could damaged your laptop and the battery and will void your warranty.

LITHIUM ION (LI-ION OR LIB)

Lithium-ion batteries are common in consumer electronics. They are one of the most popular types of rechargeable battery for portable electronics, with one of the best energy densities, no memory effect, and only a slow loss of charge when not in use.

Lithium-ion batteries can be dangerous under some conditions and can pose a safety hazard since they contain, unlike other rechargeable batteries, a flammable electrolyte and are also kept pressurised. Because of this the testing standards for these batteries are more stringent than those for acid-electrolyte batteries, requiring both a broader range of test conditions and additional battery-specific tests. For this reason alone we recommend only purchasing a replacement battery from a reputable supplier.

LITHIUM POLYMER (LI-POLY, LI-POL, LIPO, LIP, PLI OR LIP)

This type has technologically evolved from lithium-ion batteries. The primary difference is that the lithium-salt electrolyte is not held in an organic solvent but in a solid polymer composite such as polyethylene oxide or polyacrylonitrile. The advantages of Li-ion polymer over the lithium-ion design include potentially lower cost of manufacture, adaptability to a wide variety of packaging shapes, reliability, and ruggedness, with the disadvantage of holding less charge. Lithium-ion polymer batteries started appearing in consumer electronics around 1995. They are desirable in applications where small form factors and energy density outweigh cost considerations.
