If it only has an output voltage of 1.4 volts, it sounds like it has failed internally. Take it to an Invacare service centre or retailer and ask them to check it. My guess is that it need replacing. Here is the manual for it, and it states, 24 volts at 8 amps or 10 amps depending on country of issue. It charges 12 x 2 volt lead acid cells at the same time, cleverly making sure you can't use a standard 12 volt car charger. https://www.invacare.co.uk/sites/gb/files/csv_migration/product_docs/technical_docs/DTEC012618_1636951~C_OptiCharge_UM.pdf

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.
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.
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.
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.
