Hi Linda.
not sure if this will help you out,i found this on the internet.
Battery Charger Troubleshooter
When there is a battery failure, there is a possibility it was caused by a bad battery charger. When the charger is only plugged into the wall, it should show a green light. If there is no light showing, confirm that the outlet is good. If the outlet is good, it is very possible that the issue is with the battery charger, not the battery.
If the charger is plugged into the battery only, it should show a green light. (If you have purchased a new charger within the last year, you will not get a green light if the charger is only plugged into the battery. You will get a green light however if the wall charger is just plugged into the wall and not plugged into the wiring harness) If it does not show a green light, it is likely that the charger is not making contact with the battery. The most likely reason for this is a faulty fuse on the wiring harness. This fuse is a 2-amp automotive fuse, and it should be replaced with a 2 or 3-amp fuse available anywhere that sells auto parts. The fuse can blow out if there is a short in the charging system, or if the plug-in end of the wiring harness comes in contact with a battery terminal.
When the charger is plugged into both an electrical outlet and the battery, there should be a red light showing on the charger. A red light showing indicates that the charger is in contact with the battery and is actively charging the battery. Once the battery has reached a voltage level that is considered "fully charged" the red light changes to green. If after 24 hours the light has not changed to green there is no cause for alarm! Remember that when the light is red, the battery is being charged, and you will be able to use your system. After 24 hours or so, your battery is as charged as it is going to get, and if the light is still showing red you should disconnect the charger and go fishing. Replacement chargers and parts can be purchased directly from MarCum's website.
If you are really concerned about your battery, consider getting a basic volt meter to check the voltage of your battery. They can be bought for less than 20 dollars and will show you exactly what the voltage level of your battery is. If after 24 hours of charging your battery should have at least 12 volts (ideally 13-14 volts) and as long as it is over 12 volts it will work. If it is not at or above 12 volts you should consider replacing the battery. If your unit starts to malfunction while you are fishing, it would not come as a surprise that the voltage has dropped down to 11 volts or lower.
If the charger is plugged into the wall and battery, and you get a blinking light on the charger, it is very likely that the battery is faulty and should be replaced.
Batteries are an expendable item, and must be replaced periodically. Any store that sells ice fishing electronics will stock suitable batteries. You can also buy them at a specialty battery store, or by ordering one from our website.The batteries that you should use are the "Sealed Lead Acid" variety, they are 12 volts, and range from 7 to 9 amps. The more amps the battery has the longer it will run on a full charge. Your MarCum unit can be powered off of any battery that is 12 volts, even a large automotive or deep cycle batteries will work.

not exact, to charge apropiate needs 10% more than nominal voltage. if not, will not charge the batteries.
And the charger its very important because you can over charge the battery.An example,if you have a 12 Amps Batteries each one if you put it in series will be 24 Volts.at parallel conection will be 12 volts but the double of Amps.
At serial connection will be 12 Volts the amps will be the same but the volts will be 24.

The charger at 12 Volts must be 13.8-14.5 DC Volts and divide the Amps in Hours.
The charger at 24 Volts must be 26-28 Volts. to charge well.

The charger for 12 amps batt example must charge 2 amps per hour at 6 hours = 12 Amps.(2 Amps Charger by 6 Hours Charging= 12 Amps.(Fully Charged.
3 Amperes Charger needs 4 Hours to charge 12 amps Batt.
5 Amperes Charger needs 2 Hours charging an a quarter
All of this is at DC Current.

Luck.

Batteries must be stored on a full charge. For extended periods they should be disconnected. If your batteries are flat/dead the charger will not attempt to charge them. You should remove your batteries and check and try to charge them individually. Sometimes they will come alive, must of the time they won't. Charge them individually with a 12 volt 2 amp charger - no higher; or in series with a 24 volt 4 amp charger.

sounds as though the battery needs replaced, can check and see if it has a warranty on the battery. Hope this helps Tim

Don,t worry about lights,just check if the batteries get charge.If not your charger is fry.Is time to buy a new one.

Is this a toy? Is this equipped with deep cell batteries? Checked the water? Check the voltage of each battery in the pack ... should be 6 volts each ... charger putting out? Check while charging ... should be 25+ volts (make sure you measure DC.

If you have a battery that is particularly low ... it will have to be charged independently ... If this is the case, with a 6 volt charger - charge that battery. If you have two batteries that measure low ... you can charge with a 12 volt battery. You will not have to disconnect anaything to do this ... just watch what you are doing ... do not use the unit charger AND the 6 or 12 volt charger at the same time.

I hooked a 12 volt car battery charger to the battery for about two min. Then I put it in it's own charger,the yellow & green lights came on for about 5 sec. then the red light came on . About 30 min. later the green light came on and the battery is fine.

Although what the previous post is correct, if the battery is new, and if you have the peg perego charger, you need to charge it 36 hrs the first time. After that, you can charge overnight. The peg perego charger has a small light on the front.When you plug the battery in the plugged up charger, it will show amber. When battery is charged it will show green. Don't leave it plugged up, after the first charge, longer than 24 hours.
