solar trickle chargers

Post by RobC » Mon Sep 14, 2015 1:04 pm

I don't use the BX much, and what with the clock, radio memory, and alarm fitted there's a parasitic drain of around 50mA which I can't lessen.

So I bought the basic solar trickle charger from Halfords. It stopped working eventually - and I was also dubious about the voltage regulation because there was evidence of overcharging due to crusty white deposits around my battery.

Can anyone recommend a decent one that won't fry my battery yet will keep it topped up? I guess I could fit my own voltage regulator to a cheap one too.

Try Maplins, their stuff seems to be decent quality, or try Go Outdoors - they have a good range of solar chargers.

Thanks guys - I went for Maplins in the end: http://www.maplin.co.uk/p/solar-powered ... rger-n59fu

Testing it out of the box it seems to put out about 17-18v in direct sunlight. Is this not too much for a 12v battery? Or is it more about the current rather than voltage?

The cig lighter socket is always live in a BX, so I plugged it into that. However, measuring voltage at the battery it was only showing 12.8V (i.e. the same voltage as the battery). Could BX wiring be so crummy that it loses that much voltage just travelling from the lighter socket to the battery? I could hook it up direct to the battery but that's a bit more of a faff.
