NzWhat sort of charger would we need to charge the battery at home of our SJ50QT scooter? Thanks

the type of battery these mobility scooters use do not charge if the battery gets really flat. I had a relative who had his scooter taken off him by the nursing home and they left it stored in a shed without plugging it into a charger . Once it got flat the batteries would not charge at all. If only they had left it on a float charge . https://www.everybattery.com.au/deep_cycle_battery_charging.php
"Here's the problem: Most battery chargers have built-in safety features that may prevent chargers from recharging deeply discharged batteries." for more info https://www.optimabatteries.com/en-us/support/charging/resuscitate-deeply-discharged-battery

The battery needs to be tested, if that is ok have the battery charging system tested.

Charge without the key on. Make sure your charger is applying power to the scooter. It may have a blown fuse or some other internal problem. If your batteries were totally discharged your charger will not recharge them. You'll have to charge them individually with an automotive style battery charger that is NOT an automatic charger. It may take 3 days continuous charging to recover enough charge before your scooter charger will continue to charge until the batteries are fully charged. If this doesn't work then the batteries will never take a charge nad need to be replaced.

Could be scooter battery voltage is too low for charger to charge battery.

(It is a problem with gel cell batteries I have got a scooter that won't charge at all at home am going to try jump starting with another battery to fool the charger but I might have to buy new batteries.The Nursing homestaff took the scooter off my father in law and left it in the shed to get nice and flat instead of leaving it on float charge I should send them a bill for new batteries

tar the batteries are probably too low to charge with the scooter charger and need to be replaced. With the charger plugged in it will indicate a full charge beacuse its reading the output of the charger but when you unplug it the batteries are too low to indicate any voltage. hope this helps you

No, you don't need to turn on the key to charge. Just plug in the charger and turn on the charger if there is an on/off switch on it. The charger indicator and the scooter meter will read full when the scooter is fully charged. Hope this helps.

Make sure that the charger is fully connected to the scooter; ususally the controller lights will go slowly left to right to indicate it is charging. Make sure the charger is plugged directly into the grounded wall outlet, not into an extension cord or power bar. If the charger is not being recognized by the scooter, you may need to replace the charger, or at least the power cord to the charger.
If your scooter has been sitting unused for a while? If so, the batteries might not charge anymore and will need to be replaced. Contact the manufacturer for a service call or troubleshooting over the phone.
Good luck!

The Sonic has an off board charger. IF the scooter is not charging, you may need to replace it. If you a technically inclined, you can measure the voltage out of the charger, it should be more than 28 V. You may need to contact Pride for more help.

Larry,

Many scooters use a special charger that will not overcharge the batteries. Your best bet is to run a long extension cord to wherever you are safely storing you scooter and use the on-board charger. Be sure to charge your batteries often, since they last a lot longer if you do not run them down too far.

NashvilleDan, this scooter has 2 12v 10 amp batteries in series, you should read over 24 volts at the charging hub if the batteries are good. I would think that if the scooter sat for over a year you have bad batteries, They can be purchased at battery plus.
