Starter battery drain

[Anfyb]

Hi,

I have t6.1 with a ctek 250se and a Duritc battery charger. Just ordered a BM2 as the starter battery is being drained. The van is standing for weeks at a time and I’m leaving on the EHU at weekends but the charger is only charging the leisure battery. Is there a way to stop the starter battery drain apart from driving it and is there a way for the battery charger to charge both as they are connected via the ctek 250?

Thanks

if your on EHU there is your 240v source for another battery charger to charge your SB

This would mean disconnecting it from the leisure battery would it? Is there a way for it to charge both?

I did search but couldn’t find anything. This link talks about using the 250 to charge the starter but it only trick charges from solar which I don’t have. Are you suggesting either get solar or disconnecting my battery charger and connect directly to the starter leaving the 250 to pull from the starter to charge the leisure?

just buy another battery charger for you starter battery and leave the leisure battery charger alone

That would mean another £100 for one plus running wires from the back of the van to the starter. Just thought there might be a cleaver way to do it off the one with some rewiring.

Sounds like a good case for an Ablemail AMT12-2 which you would fit near the CTEC with 3 simple cables. It then trickle charges the starter battery from the leisure battery.

don't over complicate it get a 5amp charger that plugs into a 12v outlet ie cigarette lighter outlet and plug into one of your 240v sockets in the van job done £80 charger is cheaper than a new battery

The link to @Dellmassive's post covers just about every available option, just choose the one that suits your situation & budget.

Seems like that could work. As there is a positive from the starter to the ctek 250, I presume I could tap off it here and like you say it’s neatly next to to the ctek and leisure battery?

Not sure how all the boxes play together as the charger charges the leisure when EHU and then trickle the starter battery. When the vehicle is running / no EHU the starter charges the leisure via the ctek 250 as it does now.

It'll work fine, that's a standard setup & is what the AMT12 is designed for.

As Salty Spuds says that will work fine. AMT near the CTEK with one cable to the positive from starter battery, another positive to the CTEK output to the leisure battery and a negative (to the neg on the CTEK or nearby neg point). Leave and forget. No more flat starter battery.
