What is mAh or watt hour?
Lastly you must look at the power rating of the item you?e
buying. As technology advances, so do power ratings. The battery you bought last
year may be twice as strong this year, and might even be the same physical size.
Batteries have two main ratings on them: Volts and Amperes. Because laptop
batteries do not carry a very large amount of power when compared to larger
batteries such as car batteries, most companies show their ratings with Volts
and Milliamperes. One thousand Milliamperes equals 1 Ampere. When buying a
battery, always go for the battery with the most Milliamperes (or mAh).
Batteries are also rated by Watt-Hours, perhaps the simplest rating of all. This
is found by multiplying the Volts and the Amperes together. We will now show you
an example of finding the Watt-Hours for our example battery.
Our example battery is 14.4 Volts, 3600mAh
(remember that 3600mAh is equal to 3.6 Amperes).
14.4 x 3.6 = 51.84
How to install or replace your Laptop Battery
1. Turn off and unplug your Laptop. Make sure the laptop
is unplugged.
2. Locate the battery compartment and remove the battery
3. Insert the new battery.
4. Plug in the laptop and boot it up, once it is up - you should see the
charging icon
5. Charge the battery for up to 10 hours. Overnight is the best. The
battery fuel gauge may read full, but it probably isn't.
6. After the battery is fully charged - unplug the laptop and fully discharge
the battery.
This can be done by continuously playing ad CD or DVD.
Repeat this a least a couple of times.
