Why Gel Is the Right Choice for Daily Mobility Use
If your scooter or power chair is your primary way of getting around, gel is the smarter long-term investment over AGM. The electrolyte in a gel battery is completely immobilized in a silica gelling agent — making it spill proof in any position and significantly more durable under the deep daily discharge cycles that mobility users put their batteries through.
- No memory effect — recharge any time without reducing capacity
- Completely sealed — no liquid, no spills, no fumes
- Superior cycle life for complex rehab and high-demand power chair use
- No equalization charging required — faster recharge time
- Can be installed upright or on its side
- FAA, IATA and UPS approved — safe for all travel
Important: Gel batteries require a gel-compatible charger. Using the wrong charger can damage the battery and void the warranty. Call us before ordering if you are unsure about your charger compatibility.
