Hi all,
I was just wondering...
I have put a 1.5w solar charger on my car battery (around 50-60Ah) and was wondering if it is safe to leave it connected indefinately with no charge controller or do I risk boiling it away (the electrolyte levels are perfect at the moment)?
Its only there to keep it topped up while Im not driving it as starting it up for 15 mins every few days doesnt seem worth the diesel or the time.
Max output 125mA, connected directly to the battery (which is disconnected from the car anyway).
Any thoughts? I do have a spare C/C I could use but its not very good (off at 14.2v on at 13.2v).
Thanks.
