Universal 24BC8000L-1 24 Volt 8 Amp AGM Battery Charger 71714

The Universal 24BC8000L-1 24 Volt 8 Amp AGM Battery Charger is particularly suited for larger mobility applications like wheelchairs or scooters that use the standard 3 pin XLR connector and use U1 size (33 AH) AGM batteries or larger (EXCEPT Everest-Jennings chairs). These units are specifically built for mobility applications. Proper maintenance of lead acid batteries keeps them healthy, and increases their life expectancy. The float mode in these chargers allows them to be connected whenever the chair or scooter is not in use, keeping the depth of discharge in the batteries to a minimum. This increases battery life. This is a durable cased unit. The 24BC8000L-1 is excellent for use on deep cycle batteries. Universal part number 71714.

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. For this reason, each mobility charger we ship is individually tested on our bench before shipping. We ship from Oregon, so if you are on the east coast, shipping takes about a week, unless you upgrade the shipping. 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 is 2 years, 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.
5. Shipping damage, which should involve major damage to the box, as these are very durable units. Keep the packaging and call.

Universal Battery Chargers

Universal battery chargers are microprocessor controlled, fully automatic electronic devices, which use switch-mode technology to change AC input voltage to DC output voltage at much faster rates than traditional ferroresonant type chargers, which allows for a much smaller transformer, and therefore less size and weight, and increased efficiency. This can also be used for bulk charging 24 volt battery packs (AGM or wet) up to about 100 amp hour (ah).
