Mobility scooter battery charging

Does anyone charge their mobilty scooter battery en route, while driving?

If so, what size inverter do you use & how long does it take to fully charge it?

Live for today, for tomorrow is promised to no-one

Hi Blade
if its a 12v battery you should be able to charge this withour an inverter just like ou would a leisure battery via a splt charge relay.

thats how caravans charge their battery in the caravan

A battery to battery charger will get your scooter's battery charged up while you're driving, and do it a lot quicker as well.

If you've got 2 X 40AH batteries in parallel, you can plug into the vehicle or leisure battery system with something like an Anderson connector and use the charging systems there to recharge the batteries.

The main consideration is the charging voltage, which will be OK for a recharge overnight or on the road, but not for continuous charging over a few days or more.

The cyclic charge voltage for a typical sealed lead-acid battery is 14.60 which you probably wouldn't achieve with road vehicle alternators, but it will get back most of the charge for you.

Using an inverter to run a charger is not the most efficient use of power as both have inbuilt losses, but for convenience sake they may be the best option.

If using an inverter, hopefully the charger used at home will have the watts on it or they can be worked out if it shows the amps using AMPS MULTIPLIED BY VOLTS = WATTS, that will be the minimum size inverter needed, your volts will be 230v ish.
