My torch appears to no longer want to charge, so using my keen engineer's brain I have deduced that this is either down to a duff battery (likely as it was left flat for ages) or a dicky charger.

I plan to replace the battery first, but I am loather than a loathe thing to pay the DIRdirect price of £56 for a replacment battery when the battery itself should only cost about £20 and the connector soldering i am quite capable of doing myself.

Only thing is, I do mechanics, not electrics and HID lights worry me....so, seeing as i can't seem to find a direct match for the existing 12V 2.9 Amp Hr battery that is duff, should I go for a 2.8 Amp hour or 3.3 Amp hour?

What risks am I taking with either of those choices?

Cheers

Hi Lou,

Go for the one that fits in the canister :) Seriously, either of the 2 options will be fine, just as long as it actually fits. Then just be careful when putting the wires back onto the battery to get the polarity right.

if the replacment 12 volt battery fits in it will work, Maplins would be a good place to look.
If you solder it the wrong way around the balast will let out all the magic smoke :) and never work again.
So just unsolder one wire from the old batery then solder it on to the new, this should make it harder to get it wong.

As said whatever fits, current capacity will have no affect on your torch other than lasting a little longer.

RS components woud be the cheapest place, failing that then CPC will be the next cheapest. Maplins is retail, RS is trade, CPC is between the 2.
