![]() ![]() A simple thing like leaving a light on can drain your battery overnight and ruin your day. However, many things can drain your battery faster and prevent it from starting the vehicle. Depending on the temperature, the battery’s age, and other factors, a healthy battery should hold enough charge to start a vehicle up, even if it was not used for two or three months. Modern vehicles have many electronic components consume some battery power even when parked. The alternator, which is powered by the engine, charges the battery while the engine is running. Once the engine is running, the battery works as a buffer between the alternator and the vehicle's electrical and electronic components, keeping the voltage steady and absorbing any eventual tension pike. The most important function of batteries is to store enough power to make the starter motor work and start the engine. The pins or holes are marked.What you need to know about car battery chargers 12V and 24V The chair receptacle (female) will be the mirror image of this. Correct polarity for the charger plug (male) is shown above. 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. This includes Pride (except “Victory”), Hoverround, Invacare (except Lynx 元), 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. ![]() These have the 3 pin XLR connector found on about 90% of the wheelchairs and scooters in use, and wired the most common way. The polarity at the connector may be reversed. If the run time is getting less and less, the batteries are coming to the end of their life.Ĥ. ![]() The deeper the discharge, the fewer the cycles. Average battery life in a mobility application about 12-18 months, and less if the batteries are deeply discharged/recharged on a daily basis. Disconnect each cable connection and clean/scuff all battery posts and cable ends. This can prevent the charger from recognizing a viable battery pack, similar to #1 above. This will prevent proper current flowing out, and back in (charging). 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 is a very common problem in mobility applications, and a lot of chargers are purchased unnecessarily when the batteries are the problem.Ģ. There are ways to deal with a battery pack below 16 volts, but it’s possible the batteries are not recoverable. The charger has to be connected to a battery pack to check these functions. 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. Usually, if the chair/scooter won’t move, this is the case. 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. 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. This is a 24 volt charger, for a 24 volt system. If the mobility charger doesn’t work on your scooter/chair out of the box, there are several possibilities:ġ. There are a lot of mobility chargers that are purchased when there actually is a chair/scooter wiring/connector issue, or a battery problem. Information on wheelchair/scooter battery charger vs. Avoid leaving the charger plugged in for an extended period when not charging the battery.Disconnect the charger first from the power outlet, then from the battery.GREEN LED will come on when the charger has switched to FLOAT CHARGE, indicating that the battery is close to being fully charged.After hooking battery up to the charger, RED LED will light up indicating FAST CHARGE.Plug in the charger before connecting output leads to the battery.Make sure the charger's output voltage matches the battery's input voltage.Please ensure that this is the correct connector for your needs. Class 2 charger has a 3 Prong "Male" XLR Connector. ![]()
