knowing Haynes they would suggest you use a car battery and jump leads.
Tell me sbout it, maybe they should bring out a Haynes Manual for the human body. That way when you have a Heart attack whilst looking at the price of Haynes Manuals, you'd be able to fix your own body yourself too!!
Only if it comes with the optional defib but that is an extra £19.
Ahh but then you have the quandary of whether to use a standard battery with standard leads or a heavy duty battery with heavy duty leads. Ahh forget that they are out of stock. They do have some D cell batteries on a special offer though.
