About six months back brought a mini jump starter that uses a L-ion battery from Autobarn. It is a SJS 12800mah job claiming to start three litre diesel and six litre petrol motors. A couple attempts failed mainly due to the battery not being the problem or me stuffing up so went back to jumper leads. Anyway, took a while before struck a vehicle in need. Luck would have it a 6.3 litre Caddy. A quick test revealed the click of the starter relay but not much else.
Ok worthwhile target to push the little beast to its limits. Say four months under the seat not been charged. Test suggested full charge so give it a go. Bit of sparking when connecting was promising. Let it connected for thirty seconds and the Caddy turned over slowly but with not enough kick. Ok rest for thirty or more seconds and try again. Caddy turned quicker and burst into life. It worked.
Must admit when buying it I avoided my usual overkill nature and dodged it's much more expensive bigger brother as rather dubious of such a thing. Laptop will run off it but not for long and two iPad charges and it is flat. Thought I had been conned but it did start this hunk of American iron bigger than its claimed capacity with a flattish battery.
Probably now in retrospect should have brought its bigger brother, but it does neatly fit and live under the driver's seat while its bigger brother might not in is bigger plastic hard case. The starting knocked it back to three of its four bars so a few more attempts left. Series number suggests 500 amps cold cranking but manual claims 300amps.
So put one on your Christmas list as they do work. Found out work has one used to start trucks driven infrequently. General engine size around three to four litres diesel and I think it is a 16800 or greater capacity.
