Car battery remote disconnect / saver?

[JOEPRO]

What are you using to test the batteries?

@JOEPRO seconded, what are you using, a sort-of-mate has occasional problems with battery drain and the graphing function may help narrow down any variables...

The screenshots on page 2 of this thread are from this newest one I have. Cheapest on ali express, it's about double the price on amazon UK

I just found this on AliExpress:

I also have a Topdon battery tester which is very accurate but it doesn't log live data like the one above which I presume is what you mean.

PS the solar battery charger is working amazingly well. That W140 has a 100% charged battery all the time now.

Thanks for that - found the same one on fleabay for £25.49 https://www.ebay.co.uk/itm/387387129102
So I'll send him the details - I've got all sorts of battery testers, data loggers etc. but as he's very 'cost conscious' and I need my kit at work, not languishing in his car for weeks on end it'll be worth giving it a go to see if there is a battery drain issue or not.

Glad to hear the solar charger has done what we'd hoped it would.
