Lucas stuff is fine.

only problems is when someone plays with it.

switches and terminals corrode/oxidise, you can fix that by polishing the contacts in the switch with your leather belt.

all Lucas switchgear can be pulled apart and serviced.

Ive used them before. Made no difference to anything, but I don't run long intervals. Its a filter, it filtered. A+ would buy normal Ryco again because cheaper.

I do recall they have a nice grippy texture though.

Can anyone recommend a solar powered battery charger/ maintainer?  

I've recently got a work van so the daily is now sitting for long periods between uses with the alarm set. I'm wanting something that'll maintain the battery so I can just jump in and use it when need be (car is parked outside).

Would something like this be suitable?

Hoping I can sit it on the dash and plug it into the cigarette lighter. Thoughts?

I've had a quick search on here for this info but my search skills are probably mediocre.

Probably fine, but check: Does the cig lighter stay on when the ignition is off?

If not, you'll need to wire in the solar (fuse it!) or another cig lighter.

I have a 70 Watt one. Its original purpose was to power a computer fan to try ventilate a shipping container.

Now it lives on the ride on mower. I used to leave it attached all the time, but it eventually boiled the battery... over several months. Now I just stick it on every now and then.

And make sure it’s regulated somehow 

How does one achieve regulation?

Was hoping 12v 10w was low enough to plug and forget. The car will probably get used every couple of weeks at the most.

Yeah 70w is a bit high for unregulated. 2-5W prob fine, 10W maybe/probably ok on a big battery like a van

Care to explain?  Please, I have no idea.

The car is a Toyota Altezza 4cyl beams but it has the largest battery I could fit in the battery tray.

it would be made to do 12+ volts output to keep battery charged etc on a average day, same as a alternator does at idle

then on a sunny day it’ll be putting out 15+ volts, like a alternator would do at high revs- they have a regulator that stops that

so you need one for the solar panel

look for a solar battery maintainer should all be built in, or a seperate regulator
