Battery Recharging

Recommended Posts

reggie

Hey Guys,

Well the boat is pulled out of storage, waxed and ready for the water. How long do you leave the battery on the charger?

I need to charge up the battery after sitting in my garage for 7 months.

Any thoughts?

Thanks

I let it charge for 24 hours on the low setting (mine is 2 amp). You can quick charge in a couple of hours on the higher setting (10 amp), but I think the slow charge for a longer period is better.

Correct... I trickle charge my battery's at least once a month.

We usually let ours charge for 10-12 hours, but I do'nt remember what settings it is on, all I know is that when we unplug it its charged and ready to go.

Battery Tender

Read about these chargers. I leave mine on all the time. It has a float charging mode so it won't boil the battery. More like a maintenence charge.

Ronnie's right. Battery Tender or similar "smart" charger is the only way to go.

If you overcharge it will shorten the life of the battery and decrease its capacity. Also check the water level if its not a sealed battery.

I pulled this off a battery Mfg's website a long time ago. VERY useful for determiniing HOW charged your battery is:

Reading Power Left

(Volts) (%)

12.91 99%

12.80 90%

12.66 80%

12.52 70%

12.38 60%

12.22 50%

12.06 40%

11.90 30%

11.70 20%

11.42 10%

10.50 0%

NOTE: if you check the battery charge immedietley after charging, it has an extra "surface charge" that may cause the battery to be/look more charged than it is. Don't know how long you have to wait (an hour???) to get an actual accurate reading.
