hi,
Hi,

I have a mini LCD TV screen which requires a power supply of 12v -
1200mA. I would like to power the device using a battery. As i don't
want to blow up the TV i wanted to make sure the battery I use is
correct.

The voltage is correct, but I don't know what 12Ah means, which are on
the batteries. Can someone clarify this please? Thanks!

Regards,

James
