Specifically designed to fulfill the rigid international safety and performance criteria of the ISO 7176-25 standard for motorized wheelchairs, this non-spillable battery provides optimal safety and sustained energy discharge profiles. It is a high-reliability power choice for healthcare facilities, equipment distributors, and biomedical engineers managing heavy-use wheelchair assets and small industrial back-up configurations.\u003c\/p\u003e\n\u003cp\u003eOperational vulnerabilities in clinical networks often trace back to low-quality alternative battery brands that suffer from high internal resistance, rapid outgassing, or premature cell failures. The MU-1 SLD M-33-FT minimizes these critical failure modes by featuring a robust ABS plastic outer casing rated at UL94 HB flame resistance and incorporating low-resistance internal plates (approx. 6.5 mΩ) that maintain safe operating thresholds under intense deep discharge cycles. Possessing a massive maximum discharge current threshold of 495 Amps for up to 5 seconds, this rugged battery provides dependable peak-power delivery when navigating steep ramps or uneven terrain.\u003c\/p\u003e\n\u003ch4\u003e\u003cb\u003eKey Benefits:\u003c\/b\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eISO 7176-25 Mobility Certification:\u003c\/b\u003e Officially engineered and validated under international ISO benchmarks ensuring safe, reliable, and standardized performance inside power wheelchair configurations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eHigh Peak Current Output:\u003c\/b\u003e Safely supports a massive 495A maximum surge discharge current for up to 5 seconds to easily handle brief high-torque operational demands.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eExcellent Storage Shelf-Life:\u003c\/b\u003e Boasts superior charge retention properties, sustaining up to 97% capacity after 1 month and up to 85% after 6 months in normal storage environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSturdy Flame-Retardant ABS Case:\u003c\/b\u003e Built inside a durable ABS plastic housing matching UL94 HB safety metrics, shielding internal plates from impact and environmental stresses.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eUltra-Low Internal Resistance:\u003c\/b\u003e Features a minimal 6.5 mΩ internal resistance level to optimize active electrical conduction efficiency and lower hazardous heat generation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eVibration-Resistant M5 Terminals:\u003c\/b\u003e Equipped with precise M5 bolt terminal hardware paths to provide robust, long-term electrical contact points across uneven transport surfaces.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cb\u003eSpecifications:\u003c\/b\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eManufacturer:\u003c\/b\u003e MK Battery\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eBattery Chemistry:\u003c\/b\u003e Sealed Valve-Regulated Lead-Acid (VRLA)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eNominal Voltage:\u003c\/b\u003e 12V\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eNominal Capacity (20-Hour Rate):\u003c\/b\u003e 33Ah\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eNominal Capacity (10-Hour Rate):\u003c\/b\u003e 31.35Ah\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eNominal Capacity (5-Hour Rate):\u003c\/b\u003e 28.05Ah\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eInternal Resistance (@ 1KHz):\u003c\/b\u003e Approx. 6.5 mΩ\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMaximum Discharge Current (5 Seconds):\u003c\/b\u003e 495A\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eEnclosure Housing Material:\u003c\/b\u003e ABS UL94 HB\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eTerminal Interface Style:\u003c\/b\u003e M5 Bolt \/ F6\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRecommended Hardware Torque:\u003c\/b\u003e 4 N-m (41 kgf-cm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMaximum Allowed Hardware Torque:\u003c\/b\u003e 6 N-m (61 kgf-cm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCycle Use Charging Voltages (@ 25°C):\u003c\/b\u003e 14.4V to 15.0V\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eStandby Use Float Voltages (@ 25°C):\u003c\/b\u003e 13.50V to 13.80V\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMaximum Input Charging Current Limit:\u003c\/b\u003e 9.9A\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOperating Temperature Threshold (Discharge):\u003c\/b\u003e 5°F to 122°F (-15°C to 50°C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePhysical Form Dimensions (L x W x H):\u003c\/b\u003e 197mm x 131mm x 159mm \/ 168mm including terminals (7.76\" x 5.16\" x 6.26\" \/ 6.61\")\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eUnit Net Weight:\u003c\/b\u003e Approx. 22.2 lbs.
