I have a transformer rated at input 240v ac -50 hz output 13.5v dc.1.5a
Can I use this for charging regchargable torches lanterns etc. etc.
Im asuming 13.5 volts DC is fine but what about the 1.5 amps, is this enough and or whats the difference between this and a car battery. Any info would be great cheers

I suggest you don't
A fully discharged battery, even the 4Ah ones in torches, will draw in excess of 1.5 amps.
What you have sounds like a plugpack and probably will not have short circuit protection built in so you may damage the plugpack and at worst it may catch fire if left on charge long enough.
Without much more information we cannot say with any certainty.

Like Mike Harding said "I suggest you don't"
When are people going to learn to talk to qualified people about these types of issues. As an elect tech and electrician I hear these types of statements frequently and as MH has stated in previous posts you are better off getting the right advice from the right people and using the correct equipment...
That's my view so now you can all get stuck into me if you like...

It can be used to trickle charge a battery.
my in law had trouble with his bike battery, he only used it every 3 - 4 months and the battery would go flat between uses.
he now has a small charger attached to battery between uses and no more flat batteries.
Your transformer would suit this type of situation.
is it AC or DC output?
