best booster for low battery cars when key programming (UK)

**sdnatlst** · 30th April, 2019, 03:46 PM

hi all, doing more cars lately with low or no power, currently have a NOCO GB40 boost pack, small compact thing. Which is letting me down a fair bit.

i was wondering if this would be better, or what do you use please? that i can get in UK fairly quickly.

Booster is not for flash. For flash you need 15v 50amp power. Cheapers handmade cost around 250-300,good supply cost from 500-700eur.
Those boosters is joke,its just to start car,but not flash

Im not needing to FLASH i just need to make sure current is stable 12V+ while key programming

for example today i had BMW 2006 and owner was not home, car was in street, no access to outlets....the battery was poor only 11V, struggle to even start car..... i just needed to add a new key here but had some trouble because of voltage problem.

another example i went to peugeot 407 AKL in tesco car park, battery was flat dead,,, my little booster did not give enough to make over 12V on this and it made PIN read very difficult.

hope that helps why i need some mobile power booster/stabiliser

With this one from Halfords you can work all day without problem

I'm using it last 4 years

I use jump pack on the likes of Vauxhall or anything with a dodgy battery or security timer. Leads were always too short on these jump packs so a bollocks. I got 10mm welding lead jointers and a set of jump leads and cut one clamp end off the jump leads and put male welding jointer on and female on jump pack leads after cutting clamps of it. Really good job now no jump pack sitting in engine bay and handy packed up

Works well for me.
