Jumpstarter

[Deleted member 38440]

Hello
Is it acceptable to use jumpstarter without the battery in circuit, as the very flat battery would seem to drain some of the jumper power.
many thanks Graham.

The answer is yes .do not disconnect the starter battery and run engine engine without a battery connected as this would blow the alternator..

I think you need to say what sort of jump starter you are using

If your main battery is down that low it may be scrap and why did it go so low ,dont attempt to start with out a battery or a very low one as damage could be done to electronics.
Use a mains float charger to bring it up,is there not a charger in your van.

Yes van Is fitted with an intelligent charger, engine and leisure batteries all less than 2 years old. I don’t get enough sunshine on solar panels to maintain the batteries.

The charger should be on the mains plug also,i have a numax wired in and a relay to join all batts up for 230v charge.

I'd never try to start a van without a battery being present.
If battery is completely flat the best bet is to hook up another vehicle battery and run some charge into the van for a good while before attempting to start the van.

As Markd said, connect the jump leads and run the donor vehicle for a while to put a bit of charge in to your battery then start your vehicle

Never start and run a vehicle without the engine battery connected unless you want to buy a new alternator as well as a new engine battery.
