Overheating is the most common problem of laptop battery. While the laptop is using the AC adapter for power the battery acts as a back up in case of a loss of power or accidental unplugging. During this AC power use the battery becomes hotter than it would if being used independently. To lessen the chances of this overheating, which leads to a shorter life expectancy of the battery, keep the AC power adapter plugged in only if you need to charge the battery while using the device.

If the battery is consistently hot to the touch, remove it and allow it to cool down first making sure it is close to room temperature before reinserting it. Should the battery continue to overheat or get too hot it will probably need to be replaced. Always replace a defective battery as soon as possible as it could cause irreparable damage to the laptop in question. In addition to overheating failure to charge or hold a charge is another very common issue with laptop batteries.

First check to see if the AC adapter is securely plugged into the device; the tightness of the connection will vary form laptop to laptop but it should be held in place well. To check for a good connection look for the battery charging LED if one is present on your laptop. If it is not on wiggle the cord to see if the connection makes and breaks contact. If you notice a flickering LED light then the solution is a new adapter which is far better than needed to purchase a new battery or a new DC power jack which can be repaired by a common user with a little instruction and help.

What to Know Before Buying a Replacement Laptop Batteries?
There are many laptop batteries manufacturers, and even more retailers to buy your laptop battery from. However, your biggest concern in purchasing a laptop battery will be to choose the battery that fits your computer. For this you will need to know the make and model number of your laptop; if you don't know this offhand or don't have the necessary paperwork, check the inside of your laptop's battery compartment while the computer is off and unplugged. There you should find the model number, along with some other information. You may also find the part number of your laptop battery, located on the casing of the battery itself.
How to Choose a Replacement Laptop Battery?
When buying a laptop battery, you will probably only have one or two choices that fit your computer. Choose the battery with the longest life available for your computer. There are several different kinds of laptop batteries; because the technologies of each are very different, a laptop must be designed specifically for the type of battery it uses.
