12 volt 6 amps to quickly charge it from dead/flat or very low.

12 volt 2 amps as a trickle charge to maintain the battery when you are not using the vehicle for an extended time.

Okay, I'm working on a scooter for my nephew that originally came with (2) 12 volt 12Ah batteries minus the charger. and I know I need to replace them with (2) batteries of the same 12 volts and lets


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.

How do you charge the 12 volt battery with a 6 volt charger


  • A 6 Volt charger will charge a 12 Volt battery, it will just take twice the time to get the 12 Volt battery to full charge as a 12 Volt charger would take. V*I=W. It will take up to 36 hours to get a full charge from near dead but it will work just fine.

My battery has discharged. I bought a new charger, but it seems to not carge the battery. Any actions or is a new battery needed?


I took my totally discharged batteries into an auto supply store and they left them on their charger overnight. There was no cost for that service and the batteries came back to life and have lasted an additional 6 months. I just replaced them with 12V 15Ah batteries and am getting much better performance now. The total cost for the new batteries was about $70, including delivery.

I just bought new batteries for my Pride Ultra Go Go, but can't get them to start charging when I plug the charger directly into the outlet. Help please.


1.Make sure you installed them correctly.
2.Check the voltage on the batteries. If either (or both) register less than 11 volts, either return them for ones that have 12 volts, or attempt to bring them up to 12 volts with an automobile battery charger. Once brought up to 12 volts, install them, then make sure you recharge them with the supplied charger/adapter before or when the on-board indicator it shows low (red). If the battery voltage drops too low, the supplied charger simply won't even try to charge them.

Need battery


We have one of these, it's great.

See these links:

I would try removing the battery and charging it with a proper low-amperage charger (1 amp). Your battery will either be 6 volt or 12 volt, just be sure the charger matches.

Also check the ground rod and all wiring connections.

Meter Explanation


You are correct on all accounts. A high number means you dying battery is sucking more juice from the Schumacker. A low number means the battery is not as thirsty. That's how I always think of how to read the meter on mine. Slow charge is a better, deeper charge. The quick charge will get you going, but you should maybe follow it up using the normal mode - car alternator and prolonged drive time. I never use quick charge, personally.

CANT LOCATE CORRECT CHARGER


Howdy,
Most office supply stores and home supply stores, Office Max, Office Depot, Staples, Home Depot, Lowes, carry a Universal AC Adaptor that has multiple voltage settings with multiple plugs that fit a variety of low voltage charger connections.
