Relicell 18 Ah 12 Volt SMF - VRLA Battery
Quick Specifications
Product Overview
The Relicell 12 Volt 18 Ah SMF - VRLA Battery offers enhanced energy capacity within a compact, sealed, and fully maintenance-free package. Purpose-built for systems requiring extended backup duration, this VRLA battery combines the core advantages of zero maintenance with robust deep-cycle performance, making it an ideal upgrade from smaller capacity models for more demanding applications.
Perfect for home inverters, solar energy storage systems, electric scooters, UPS backup units, access control infrastructure, and industrial alarm panels, this battery delivers sustained power output across a broad operating temperature range. Its completely sealed, spill-proof AGM design makes it safe to install in any orientation — whether in a wall-mounted panel, under a desk, or in a vehicle-mounted enclosure — without any risk of electrolyte leakage.
The Relicell 18Ah battery is engineered for high discharge rate capability, allowing it to handle sudden power demands without significant voltage drop. Its long service life in standby applications makes it a cost-effective choice for systems that require the battery to remain on float charge for extended periods. The flame retardant ABS housing ensures safe operation in enclosed environments, and the low self-discharge rate means the battery remains operational even after prolonged periods of inactivity, making it the ideal mid-range SMF - VRLA battery choice.
