Jump Starter Pack

[jims-terrano]

How on earth can a little starter pack really work, can’t imagine it touching a terrano or even a smaller engine.

The car trade have used the slightly larger versions for over 10 years to start everything including 3 litre diesels- lighter than carrying a slave battery around the showroom. That said it is to start a new engine that just has a flat battery not to crank over a vehicle that will not start!

They use them at local MB dealer one charge will start quite a few vehicles. They don't last that long when hammered - they just loose the charge presumably when the charging cycles have been used up.

Not used the modern compact versions - I am old school I have a 120 Ah spare battery I am fortunate enough to have the same battery casing size in all 3 of our vehicles.

lithium polymer & ion batteries can supply insane amounts of power. For this application even if it's for short period of time is enough to jump start a vehicle a few times.

Although my friends one wires melted trying to jump start his diesel van. No idea on the make.

The connections to the battery do look like the weak spot of some jump packs, they just do not seem to have the core size to carry the amount of current required.

i had one and the battery kept loosing its charge so took it apart and its only a 17ah battery in the one i had,looked for new battery but almost as costly as getting a new unit.in the end i did not and have a spare 100a terry battery.
it fitted both 2.7 but the terminals are wrong for my 3l.
in the winter i did not use 3l for 3months and needed a jump,i put it on charge but lucky for me a neibour had called out a local garage to get there car started and i knew him from old and he got there car started and came over and jumped mine but it was a big power pack.i was happy as he did not take the fiver i offered as he said they paid lol.
i kept the compressor bit as was going to fit it into front of caraven with cioled hose,never did though.
so the big ons are ok for big ons and the smaller ones ok for cars in my view.

many of the older cheaper bigger ones only have a small motorcycle gel acid battery inside them.
