In my line of work I jump start cars all day long.
Employer supplied me with a Clore JNC660(425amp crank/1700 peak) which would start just about anything except maybe a completely dead AGM. with these cold snaps I come across dead AGMs a lot more, even some lead acids that I can’t start with the JNC660. My current solution is to run the pack alongside jumper leads from my work truck to get these vehicles started. It works, but a major hassle and sometimes isn’t possible as the truck is too tall to fit into parking garages.
Anyways I’m planning on picking up a second jump pack to make my life easier. Considering I don’t ever see anything over 850CCA could I get away with a cheaper 330 crank/630 peak jump pack in addition with my JNC 660? This would put total at 755 cranking amps and 2230 peak.
I have no clue how cranking amps and peak amps come into play with jump starting completely dead batteries. Electrical has never been my forte. Trying to decide if I should fork the extra money over for a matching capacity jump pack so I have 2x the power instead of 1.5x. HF is selling 500/1700 peak jump pack for $170 where as the 330/630 pack is $70.
