Another leclic question, Charging

I think Hans says it´s alright to leave the charger on, you can´t overload the batteries because the charge will stop, do I remember rightly please?

I think that's right Jan - I've never heard it's a problem. In fact it's far better to allow the batteries to remain topped up rather than them running down and being continually topped up after they've become "run down".

Just a couple of things to be aware of:

1) The charger works best if it is a "smart" charger: this will go through a number (usually 5) to get the battery into the correct level of charge, using "smart" electronics. My original charger (2001-build) wasn't quite smart enough and burnt out, shorting itself and tripping the electrics. It was reasonably easy to replace it with a smart one from a supplier.

2) My son's caravan is parked in our garden and one day we had a horrible smell like rotten eggs. The battery was dead in one cell and low in acid in the rest, so the charger kept pumping charge into it. This caused overheating and gassing: it's always worth checking your situation.

For vehicle batteries a marine type 'fit & forget' type charger that shuts off when full and only starts charging again when the volts drop.
Nothing to do with phone chargers Jan but again don't worry about it unless on a flight.

It is generally best to charge batteries in cycles (not bikes!).
They can be left on charge for very long periods (days, weeks, months) with a reasonable 4, 5, or 6 stage charger.
However When not in use, but connected it is best to charge for a day or two then rest for a week or two....depending on the drain.

Gordon indicates the problems of continuous charging!

Be aware that any battery has a finite number of times it can be discharged and recharged.

I would think as the Navajo was built in 2014 and has this super sonic confoooshus blessed Sargent that tells ya everything gadget, its got a smart charger so to go with that I´ll soon have me smart phone.

Thanks boys for all your explanations,I take it I did right leaving it on because we have 2 leisure batteries to charge.
