|MobilityCharger 24 Volt, 3 Amp Mobilty Charger
24 Volt, 3 Amp Charger
Class 2 charger has a 3 Prong "Male" XLR Connector.
Please ensure that this is the correct connector for your needs. There are NO refunds on this item.
Reversed polarity protected.
Green: Power on, Float Charge
Red: Fast Charge
Proper Charging Procedures:
- Input voltage: 100-240V AC, 50/60 Hz
- Make sure the charger's output voltage matches the battery's input voltage.
- Plug in the charger before connecting output leads to the battery. GREEN LED indicates power is ON.
- After hooking battery up to the charger, RED LED will light up indicating FAST CHARGE.
- GREEN LED will come on when the charger has switched to FLOAT CHARGE, indicating that the battery is close to being fully charged.
- Disconnect the charger first from the power outlet, then from the battery.
- Avoid leaving the charger plugged in for an extended period when not charging the battery.
Information on wheelchair/scooter battery charger vs. battery problems
There are a lot of mobility chargers that are purchased when there actually is a chair/scooter wiring/connector issue, or a battery problem. If the mobility charger doesn’t work on your scooter/chair out of the box, there are several possibilities:
1. This is a 24 volt charger, for a 24 volt system. A 24 volt battery system with healthy batteries measures 25.4 to 25.5 volts at full charge, and 23.8 to 24.0 when effectively discharged. If the batteries are severely discharged, to a point below 16 volts, the charger won’t recognize a viable battery pack, and won’t begin charging. Usually, if the chair/scooter won’t move, this is the case. Because of this safety feature, you can’t measure charger voltage or current at the 3 pin plug, without the charger being hooked to the chair. The charger has to be connected to a battery pack to check these functions. There are ways to deal with a battery pack below 16 volts, but it’s possible the batteries are not recoverable. This is a very common problem in mobility applications, and a lot of chargers are purchased unnecessarily when the batteries are the problem.
2. Even though the terminal connections may look clean and tight, there may be insufficient contact at one or more cable connections, for good electrical contact. This will prevent proper current flowing out, and back in (charging). This can prevent the charger from recognizing a viable battery pack, similar to #1 above. Disconnect each cable connection and clean/scuff all battery posts and cable ends. A wire brush, battery post cleaner, etc. works well for this.
3. Average battery life in a mobility application about 12-18 months, and less if the batteries are deeply discharged/recharged on a daily basis. The deeper the discharge, the fewer the cycles. If the run time is getting less and less, the batteries are coming to the end of their life.
4. The polarity at the connector may be reversed. These have the 3 pin XLR connector found on about 90% of the wheelchairs and scooters in use, and wired the most common way. This includes Pride (except “Victory”), Hoverround, Invacare (except Lynx L3), Permobil, Drive, Ranger, Sunrise, Quickie (models with off-board charger), all Golden (except “Companion”), Bruno, PaceSaver (off-board charger models only- Atlas Plus 3, Eclipse, Esprit), Shoprider (except Sunrunner Deluxe and Lithium-ion battery models), Heartway, Merits (all with off-board chargers), AND most other mobility scooters and power chairs with off-board chargers & XLR connector. May not be compatible with some EV Rider, Zip’r, E&J, or Worldwide Seating chairs using the XLR connector, as Everest-Jennings and these others reverses the wiring on pin 1 and 2 in the connector. Correct polarity for the charger plug (male) is shown above. The chair receptacle (female) will be the mirror image of this. The pins or holes are marked.
