Keeping A 7Ah Charged Via 12V In Vehicle

[Rulland]

As title, easiest way to connect a battery to cigarette socket to keep it topped up, this battery would be supplying LED lighting-reason for battery is so ignition need not be on to use lighting, but battery would be charged whilst driving etc, any thoughts people?.

guys.

Our factory fitted caravan Tracker has a boggo standard 7ah yuasa 'charged' via a massive diode from the caravans nominal 14.4v supply. It goes into storage twice a year with no mains and main battery isolated, for 3 and 5 months at a time. Tracker still works 3 years on (lifetime sub), will check 7ah battery when I remember to take the tester...

Split charge relay unit, only connects 7ah to vehicle when engine is running

There are a few ways to go about this, a few questions.

 

Does your ciggy socket stay live with the ignition off?

 

What is your plan for the lighting? Just incase there is a better way to do the job.

Thanks guys for the replies.

Swb ciggy socket dies with the ignition, purely led strip-5 mtrs- to go around the inside of the back.

The internal light at the back times out even if overidden on the switch.

I could just use the 7aH, but that means I gotta change it/charge it sometimes, just wondered if there is a suitable way of keeping it topped up in van so to speak.

Ta chaps,
