An important part of caring for your new powered product is caring for it. We’ve created this handy guide to help you keep your batteries lasting long.
- Always have your batteries installed by a properly trained wheelchair or scooter technician. They have the necessary training and tools to do the job safely and correctly.
- Wheelchairs and scooters typically require two batteries with a 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 with AGM batteries.
- Always fully charge batteries prior to use.
Active users of powered products should cycle their batteries daily, this 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, the range and running time of your mobility device will initially increase
When to Charge?
- Charge daily and for as long as possible, even on days with low usage.
- 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 VRLA Gel and AGM batteries do not exhibit a ‘use it or lose it’ capacity-robbing effect known as ‘memory’.
- Chronic undercharging is a common cause of premature battery failure. Charging for a minimum of 8 hours each night is the standard recommendation for proper battery function. To further enhance battery life, it is recommended that a 12-hour charge be performed at least once or twice each month.
Proper Charging Guidelines
- Never use an automotive or wet-type charger on Sealed VRLA Gel or AGM batteries as doing so will damage your battery.
- Depth of discharge affects cycle life. The harder a battery has to work, the shorter its life expectancy. Longer use typically means longer recharge times.
- 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 VRLA Gel and AGM batteries can hold a charge for up to six months, however, they should always be charged before use.
- When storing a powerchair 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 VRLA Gel and AGM batteries require no watering. Any performance-related issues should be handled by a properly trained wheelchair or scooter technician.
Batteries can be hazardous.
- Dropping a tool or touching a watch or bracelet across the terminals can result in an electrical shock, sparks, smoke, fire and even an explosion. Use extreme caution around exposed battery terminals.
- Battery posts, terminals and related accessories contain lead and lead compounds,and other chemicals known to cause cancer and birth defects or other reproductive harm. Wash hands after handling.
- Be careful! Batteries produce explosive gases. Keep sparks, flames and cigarettes away from batteries at all times. Always wear safety glasses and a face shield when working on or near batteries. Ventilate well. Do not install in an airtight container.
- Do not attempt to open vents.
- All old batteries are considered “hazardous material” and must be recycled through an approved agency to prevent improper disposal. Lead-acid batteries are virtually 100% recyclable. Be sure to return your used lead-acid batteries to a retailer.
