Are all computer batteries the same size?
The short answer is "No"
The long answer is:-
Physical size, input and output voltages, output capacity and the connection type to the PC varies from one PC to another.
If you are asking about batteries for your particular PC, then there are four things that need to match the PC's requirements, they are-:
Physical size, has to match the space provided for the battery.
Voltages, the output voltage from the battery to the PC must match the voltage required by the PC. (This can be found in the handbook, on the back of the PC, or the manufacturers website.
Battery Capacity, this is stated in one of two ways. either, in Wh,(watts per hour) or Amps, the higher this number, the longer it will run your PC.
Connections, this must marry-up with the connections on the PC.
For instance, the battery information label for my Inspiron 1720 reads as follows:-
Rating: 11.1v === Capacity 56Wh which means,
Voltage; 11.1 volts (=== DC), less than this and the PC will not run, more than this WILL damage the PC
Capacity; 56Wh means, if the PC uses 56 watts per hour, it will run the PC for one hour. If it uses 28Wh, (56/2=28), it will run the PC for two hours.
The higher the Capacity, i.e ??Wh the longer it will run the PC and will not harm your PC but, increased capacity batteries commands a price.
When it comes to the Power Supply Unit, (PSU), or "Charger"
Input: AC 100-240 volts ~ 1.5A 50/60Hz (~ refers to AC)
Output: DC 19.5 volts = 4.62A (= refers to DC)
Input from the wall socket of Alternating Current anywhere between 100 and 240 volts at 1.5A at 50 or 60 Hertz. In other words this PSU will work world wide with the right plug adaptor, (if needed), to convert the existing plug to the wall socket of the country you are in at the time.
I hope you find the above, informative and useful.
