Recharging flat batteries.

[Fed]

I dont have a 240v -12v charger...might have to look into that.

Any suggestions..?

Not really mate, it all depends on what YOU need & want in a battery charger.

I happily make do with a 'dumb' Arlec 4.0 Amp charger that is really only good for 2.5 Amps on a good day.
Horses for courses.

I don't need a smart charger & I question how smart they are when you consider the variety of batteries around, not a fan of CTEK & similar either, charging more to give less IMO.

I have a very low wattage led on my dash wired to my battery cut off switch
reminds me to turn the power off

Good thinking Steve. I leave a USB port in the cigarette lighter socket. It glows blue if batteries are left on. Always check the dash before I close up the boat. SS

I have a dual battery LED monitor on the dash but because I mounted it low so it didn't affect my night vision I sometimes miss it but as always in n out of the boat it gets spotted fairly quickly.

All good...batteries are re-charged.

I'll blame the incident on my missus..

Sometimes when I am playing around with the sounders I just turn the battery switch off without actually turning off the sounder first..

So when the battery switch is turned back on the sounder powers up without actually having to press a button..

With my missus's garmin screen cover fetish I never noticed that A..I'd left the battery switch on and B. that one of the sounders had come on when I turned the battery switch on and left it on for how ever many days or weeks since I last messed with it..

So legally, blame could probably be apportioned 50% each way if we had our day in court but morally I'll just have to admit I'm a bit of a doofus...

Lesson learnt..!

Lesson learnt re batteries but I've found that life all around is much better if the missus is blameless. Just take it on the chin.

Fed, 20 years ago this philosophy worked well. Then they took antimony out of the equation, thst meant batteries dying without any indication they were on the way out. Then they added calcium (definitly don't like being discharged) into the equation to try and have a battery that was both a start and deep cycle battery. Problem is management of these was and still is critical. I do agree Fed that most smart chargers are pretty ordinary at charging multiple types of batteries. I am fast approaching the fact that these days you need a separate charger for each type of battery.
