Don't forget to check the battery levels.
I absolutely agree !
If, while disconnecting the negative post, I accidentally touch the chassis with the wrench, nothing happens. But if I do so while disconnecting the positive (with negative still connected) the the wrench shorts the battery !!! And guess who's actually holding the tool in his hands? :'(
I am looking at fitting a cigarette lighter plug thing somewhere, fused, so that should I need something (from jumping the battery to recharging my cellphone) I have a plug available.
For trickle charging the battery, I have found a 1000 mA 3-12V DC power adapter (the kind you buy 'one size fits all' for recharging anything from Dremel drills to kids' radio controlled toys) just set it on +12V, get the polarity right, and it'll trickle charge at a nominal 800mA (more or less 10W) continuous.
