[@gabe4408]

[@bondholder604]

I put one on, but it does not completely cut the power off, still drains the battery what a pos..

What, that's strange. Sounds like a case for warranty :D

[@Ecne3D]

hmm but what's the power draw with it ON, so if you forget to disconnect the battery, the electromagnet will drain the battery?

[@henryn3850]

I was looking for the same answer as well, and it turns out an energized relay like this will drain about 70ma to 200ma of electricity in its on state, so yes in short your battery will drain faster if you forget to disconnect the battery. Doesn't look like there is an easy way around it. Maybe install a fixed solar panel somewhere inside the windshield to compensate.

Will this cause problems in the long term?

I’ve had it installed for a year now and it still works fine, didn’t even have to change the battery on the remote. For me it saved a lot of headache because now I know my battery is always full and my car can start. In everyday life nothing changed except that I need to press an extra button. The only problem I see is that when the remote is empty one day, I can’t start the car - but I’ve got a second one. Apart from that it’s just a switch, it can’t damage the car. It’s like unplugging your TV instead of putting it into standby. One thing to keep in mind is that the remote lock/unlock and the alarm system won’t work if you completely disconnect the battery like this. But then again, a thief couldn’t start it either until he figures out what’s going on :D

@@no-expert that’s the problem I ordered my disconnect switch with remote control from FEITON and it doesn’t come with a spare remote control. I don’t even know how to contact them for a spare remote control

In this case, I would put a replacement battery in your car, wallet or backpack so you always have one with you. Also take jumper cables with you (which you probably already have with you if you’ve got battery problems like me). In the case you lost the remote or the remote battery is empty you can always bypass the relay using one jumper cable, connected in the front and back of the relay. Like this you should be able to start your car even without the remote :)

[@yunusertas]

[@dustysrandom5079]

Amazon or eBay. $25 usd

[@VJLee-sx1ix]

[@no-expert]

No it's petrol, but this should work for diesel too. Just make sure to activate it for pre glow before starting :)
