When your mobility scooter or power wheelchair starts losing range before the end of the day, the battery is usually the reason. This 12V 33Ah sealed lead acid battery gives you a maintenance-free AGM deep cycle power source engineered for repeated discharge and recharge, not the shallow starting duty that automotive batteries are built for. The absorbed glass mat construction locks the electrolyte into the separator, so there is nothing to top off, nothing to spill, and no venting requirement in normal use. You get consistent, predictable run time cycle after cycle.
Low internal resistance of roughly 6.5 milliohms keeps conduction efficient and heat generation down, which matters when you are climbing a ramp or pulling a grade and the motor draws hard. The battery supports up to 495 amps of surge current for five seconds, so brief high-torque demands do not stall you out. A flame-retardant ABS case rated UL94 HB protects the internal plates against impact and vibration during daily transport, and M5 bolt terminals hold a tight electrical connection even on rough surfaces. The standard U1 footprint drops into most existing battery trays without modification, and the recessed handle makes swapping a pair straightforward. Whether you are replacing a worn set in a home scooter, keeping a patient lift ready at a care facility, or maintaining a backup power bank, this is a straightforward, serviceable power source you can install and forget about until the next replacement cycle.
- Deep Cycle AGM Construction Built for Daily Use — This sealed lead acid battery is designed for repeated discharge and recharge cycles, delivering steady 33Ah capacity in mobility scooters, power wheelchairs, and patient handling equipment.
- Maintenance-Free and Non-Spillable — Absorbed glass mat technology immobilizes the electrolyte inside the separator, so you never add water, and the battery can be mounted in any orientation without leakage risk.
- Strong Surge Output Under Load — With up to 495 amps of discharge current for five seconds and roughly 6.5 milliohms of internal resistance, the battery handles ramps, inclines, and hard motor draws without voltage sag.
- Standard U1 Fit with Secure Bolt Terminals — The U1 footprint drops into most existing trays, and M5 bolt terminals torqued to 4 N-m maintain a solid connection through vibration and rough transport surfaces.
- Flame-Retardant ABS Housing — A rugged UL94 HB rated ABS case shields the internal plates from impact, heat, and environmental stress, extending service life in demanding home and facility settings.
