Jump start battery

There are so many Jump start batteries on the market.
I believe most of them can't jump start a T1N or NCV3 with a flat battery with no other problems, but due too the main battery being used for other accessories.

The main "accessory" fighting a Jump Start battery is (are?) the glow plugs.
If you're jumping in the summer, you *might* get away with turning to crank immediately instead of waiting for the glow plugs.

Even then, the glow plugs continue to be powered for a number of seconds after engine start (temperature dependent) ... and a truly flat battery (plus jumper) may not be able to keep the Sprinter "alive" until the alternator starts producing power.

The 2nd major factor is that the Sprinter's diesel engine has about twice the compression ratio of a typical petrol engine.
(something over 18 compared to 10-to-13))
Thus it takes twice the energy to get it to turn over at all.

I use a Gooloo 2000 when the battery has become low and sprinter won't start from using the fitted diesel heater and charging accesories.
Have used twice on sprinter and once on a pajero diesel with no problems.
They now have a bigger one as well.
