Transformer use

Hairy, you can sorta, but you shouldn't. I won't go all technical but the batteries are often of different types that require different charging rates/current at different stages of charge.
Nobody wants to be buying new batteries all the time so get a charger that suits the type of battery that you need charging. It will be cheaper and less frustrating in the long term.

I assume you will be using chargers that have a Cigarette Lighter Plug on them. The chargers should have the current rating written on them - as long as it is less than 1.5 amp you will be fine.

It might be worthwhile having a Cigarette Lighter socket wired to the end of your power supply leads, that way you can plug in anything designed to use 12 volt.

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.

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?

sell it on ebay and with the money buy the right gear. Unless you know what your doing you could burn the house down. Not worth it for a few bucks

Have to agree with Marc,

The output will be ac and without technical input and full rectification call the fire brigade.

Hairy,

With that transformer, you could use it to power an old car radio, for use wherever(there is 240v power). Car radios are usually more sensitive than the ghetto blaster radios, so are good in fringe areas. We've got one here, and can pick a number of stations, all over 250 clicks away.

Hooroo...

Except he has stated its 13.5v dc in the post.So its rectified within the case.
Presumably the torch is definately 12v ? I have a 6v rechargeable unit .
If the charger output pin fits the torch it would be useful to use it with the "cigarette plug" as stated above.

I cannot believe that all the experts are telling you that this transformer is no good. I have just had a look at the plugpack chargers supplied with some of my rechargeable items with 6 volt 4 amphour batteries and they are rated at 12 volt 500 milliamps ie half an amp DC. Sure its slightly higher output voltage but you will get 13.5v out of your car ciggy plug. If your rechargeable items are meant to be charged from 12 volts then this item should be fine. Mind you, you will need to ensure correct polarity otherwise something may go ZAP.

Thanks for all the advice but to save this going any further, It was a simple question with a simple answer, it has already gone to the sh#$ house!
Thanks all
