Is a battery charger of the following strength:

Input Volts AC 100V – 240V
Output Volts DC 19V
Output Current 7.1A
Power 135w

compatible with a battery 6600 mAl or would I need a greater size charger?
both items for the same laptop.

I've already replaced the battery which is 6600 mAl (previously 4300 mAl.
Thnx for any help.

The current rating is OK (as it exceeds that of the battery). Of course you'd need to check that the voltage is also correct (as not all laptops require 19V). Too low a voltage might not work. Too high a voltage could cause damage. Then you'd need to check that the polarity of the tip is correct. (e.g. if a centre-positive tip is required, connecting a...

Then you'd need to check that the polarity of the tip is correct. (e.g. if a centre-positive tip is required, connecting a centre-negative supply wouldn't work and, if the manufacturer hasn't fitted a protection diode, cause extensive damage).

Lastly you'd need to check that the plug tip is the correct physical size for the socket. Some tips look similar but, when you try to plug them in, you either find that they won't go in or that they keep falling out.
