I have a dead charger. Does not show any voltage with a meter. I already replaced the batteries after 8 months. Should the company send me a new charger? The scooter is 10 months old.

Hi, Check the connections for tightness and use a volt/ohm meter to check for charging voltage. Anywhere between 6v and 12v. If you suspect charger, replace with same kind and Voltage output.
Also check battery(s). replace if dead. After many battery uses. They can have an internal discharge and will not work properly any more.
Good luck.

Depending on how many charge cycles your battery has had it may not accept charging anymore.

First check the battery voltage using a multi-meter set to DC and volt range if reading is below 12V battery has probably one dead cell get a new one, if between 12v and 13V battery should be OK to charge. Remove battery undo negative lead first then positive. Please do not use a car charger or any other charging device that has an output greater that 1 Amp you will fry the battery. Charge the battery for as long as possible. Recheck volts across the battery if above 13V refit battery connect positive lead first then negative.
Start your engine, when warmed up check the voltage across the battery terminals it should be well above 13 volts. Increase the revs and watch the meter the voltage should increase to about 14.5 volts. This shows the battery is being charged. Please remember batteries on bikes only last a few years and short rides do not put enough charge in your battery. Buying and using a motorcycle Smart charger does help. I use a CTEK XS 0.8 12V Motorbike Battery Smart Charger & Conditioner. You get a small wiring harness that fits to the battery with a rubber connector that connects to the chargers plug. This unit will help to keep the charge in the battery topped up.

The battery life for these lights are for about 2 years at the most if left uncharged. The best way to determine if you need new a new battery or batteries would be to dismantle the light, remove the batteries and check the voltage with a volt meter. If they are dead, you may be able to fine a suitable replacement at: http://www.batterymart.com/c-04-12-volt-sealed-lead-acid-batteries.html

Your battery might be toaast. Need to check the battery with a load on it. An volt meter hooked to the battery (good battery-12'8V) will tell you how much voltage drops when you hit starter button. SHouldn't go below 12. If you have a bad cell, the voltmeter wil drop to less than 10 V. Battery's dead/new battery req'd Hope this helps

Yes to both questions. the charger must sense 41.5 volts to activate the relay inside the charger. Being a repair shop, I have a charger that is rigged to charge even DEAD batteries. I do not recommend this for the novice. A charger set on 12 volts will bring the batteries back up to 8.2-8.6 volts. A cheap trickle charger may not put out enough to charge a battery of this size. Remember that they are used to MAINTAIN a charge. Connect the Voltmeter and watch for voltage rise. If it rises to 8.1 or above, it is charging. Trojan battery company recommends charging at least once a month.

The measurements below are for a 12 volt charger or across one battery at a time. In a 24 volt charger or across both batteries at once, double the values.
The charger will not show any output unless connected to a battery. To test the charger, attach the charger to the battery but do not plug in the charger. Connect a meter to the battery and read the voltage (9.8v - 11.6v).
Now plug in the charger. Read the battery again (13.6 - 14.2v).
The voltage must not be higher than 14.8 on the battery or the battery will over-charge - the charger needs service. If the voltage does not come up to 13.2v, the charger is not running. Again, the charger needs service.
Be patient. You can wait ten minutes and measure again. Batteries respond slowly to the charger.

It's either a dead charger or dead battery(ies). You will need a voltage tester meter to check. First check the charger by setting your meter to a setting over 24 volts (your chair is a 24 volt system). Test the voltage at the charging port by placing the two probes into the two outside ports (there's three ports in a triangle...test the two opposite ports.) You should get a reading in excess of 24 volts but less than 26. Now plug the charger into one of the ports and check the voltage again. If the voltage is now higher than the first reading, your charger is working and you will need to replace the batteries, if it is the same, your charger is bad.

Most likely the battery.
