would this kill a new battery?
Bought a new cranking and deep cycle battery for the boat a month ago. (battery 1 in a duel system , which does all the work as I never use no.2)
The other night , I had the gps on, checking some stuff for the following mornings fishing.
I turned the gps off , but I forgot the battery isolator.
In the morning I could see a light on the dash , and the motor would barely trim up or down.
Bugger.
No prob , so I started the boat running both batterys and fished.
When I got home , I stuck the new battery on the ctek charger overnight. The charger registered that the battery had a good half a charge in it when I started.
After a good 16hrs , I ve just rechecked it. It is still registering the same amount of charge in the battery but it still won't trim the engine in the driveway.
Stuffed already ?
If I spent half as long fishing , as I do reading this bloody forum , I'd be twice the fisherman I am.

Letting the batery drain
Letting the batery drain till it`s dead over night then charging it back up again souldn`t do it any harm.
letting a battery sit uncharged for long periods will stuff it though.
Batt may have been sitting uncharged for a while before you noticed it.

Sounds like a faulty battery
Is it a sealed battery or does it have a water level that can be easily checked?
Sounds as though one of the cells is starting to fail already.if u purchased the battery new I would be taking it back for a warranty claim. Most battery shops offer a 12 month 40 k warranty for cars, not sure what the boat battery warranty is but it has to be better than 1 month.

delkor are a great battery,
delkor are a great battery, and shouldnt require that long from half charge. maybe actually check the charging voltage, could be the ctek ? but sounds like a bad cell, would be replaced under warranty !

What charge was in the
What charge was in the battery above 12.6 if it isnt above that then the battery isnt fully charged.

Deep discharging (flatening)
Deep discharging (flatening) will reduce the life of any battery, though it is unusual to kill a brand new battery. Getting it back on charge quickly was the right thing to do to give it the best chance of recovery. Give it 24 hours on the charger and see if it recovers. Some smart chargers have issues with very flat batteries and may take some time to recharge it. If it doesn't recver, see if warranty will cover it.
I would be investigating why and what discharged it to avoid any battery problems in the future.

In my experience with deep
In my experience with deep cycle battery's to get them to recover and it's only a 50/50 chance they will I have to use an industrial workshop charger and that takes 24 hours I think mines around 20000 amp but it does decrease the life if I was you I would take it back play stupid and get a new one I had my last one for 5 yrs and its only just kicked it
Also leaving the isolator on shouldn't flatten it that much if everything was turned off I would be checking wiring for a voltage leak or drain

I am pretty surprised 1
I am pretty surprised 1 little led light on the switch panel could knock most of the charge out of this batt over a night.
oh well
It's back on charge and we'll see.

Charge the battery and have
Charge the battery, if the voltage is not getting over say 11 v then you prob have a dead cell. Have it load tested, if it passes at it rated capacity, check the current draw by putting and amp meter (mulitimeter)in series with either neg or pos at the battery. A 100 ah battery is rated to deliver 1 amp for 100 hours. Deep cycle batteries are suited to total drainage and recharge applications. A LED will have bugger all current draw, if you have a few amps draw then start pullin fuses until the figure decreases and that will tell you the source of the current draw. Vibration is the biggest killer of lead acid batterys, thus dry cell types like optima and odyssey last ages
I am, as I've said, merely competent. But in an age of incompetence, that makes me extraordinary.
