- Wheelchairs and scooters typically require two batteries with 24-volt series connection. Never mix and match different battery manufacturers or technologies, or use batteries that do not have similar date codes. Never mix Gel batteries and AGM batteries.
- Always fully charge batteries prior to use
- Follow installation and start-up instructions provided by the mobility equipment manufacturer.
Active users of power wheelchairs cycle their batteries daily (deep cycling). This stringent application requires a unique battery design that will sometimes compromise initial capacity in return for longer battery life. Gel battery performance improves once the battery has been cycled (discharged and recharged) 15-20 times. This break-in period is necessary to fully activate the battery for maximum performance and longevity. Thus, range and running time of your mobility device could initially increase with use.
When to Charge
- Charge Daily
- The charger supplied with your mobility device should fully charge your batteries overnight. Overcharging is not a problem with today’s smart chargers as they are voltage limited and shut off automatically. Sealed Gel and AGM batteries do not exhibit a “use it or lose it” capacity-robbing effect known as “memory”.
Proper Charging Guidelines
- Use the equipment manufacturer’s automatic charger for all routine charging.
- Never use an automotive or wet-type charge on Sealed Gel or AGM batteries as doing so will damage your battery.
- Depth of discharge affects cycle life. The harder a battery must work the shorter its life expectancy.
- Avoid ultra-deep discharges and never drain your batteries completely
- Do not leave your batteries in a low state of charge for an extended length of time. Charge a discharged battery as soon as possible.
- Do not cycle your batteries at a low state of charge without regularly recharging them fully.
Storage and Maintenance
- Always store your batteries FULLY CHARGED
- Check all stored batteries once a month and recharge as needed
- Fully charged Sealed Gel and AGM batteries can hold a charge for up to 6 months, however, they should always be charged before use.
- When storing a power chair or scooter for more than 2 weeks, charge the batteries first and then disconnect them for storage.
- Avoid hot and cold extremes when storing
- Sealed Gel and AGM batteries require no watering. Any performance-related issues should be handled by a properly trained wheelchair or scooter technician.
