12V 7Ah AGM Replacement Battery for MAX and MXG Gate Operators The Maximum Controls MX045 is a 12V, 7Ah sealed AGM replacement battery for compatible Maximum Controls gate operators equipped with local 7-amp-hour batteries. It stores DC power for battery-supported operation and provides backup power when incoming AC power is interrupted. Many Maximum Controls operators use two 12V batteries connected as a battery set, although the required quantity and battery arrangement depend on the operator model. A weak or aging battery can cause reduced backup cycles, battery voltage warnings, charging faults, slow gate movement during battery mode, or an operator that cannot complete a full cycle after a power outage. The MX045 is used across multiple MAX PRO, MXG, MAX RHINO, and MAX arm operator platforms configured for local 7Ah AGM batteries. Maximum Controls may source this replacement battery from different approved manufacturers, so the battery brand, label, and case appearance may vary from the product image without notice. The supplied battery will meet the required MX045 voltage, capacity, and application specifications. Key Features Maximum Controls MX045 replacement battery for compatible gate operators 12V sealed AGM battery with 7Ah capacity Supports gate operator battery backup during AC power interruptions Used in compatible MAX PRO, MXG, MAX RHINO, and MAX arm operator systems Sealed absorbed glass mat construction requires no routine water maintenance Common replacement for batteries with reduced runtime, low-voltage warnings, or charging faults Many operators require two batteries; confirm the required quantity before ordering Battery manufacturer and appearance may vary based on Maximum Controls’ current approved supplier Technical Specifications Maximum Controls Part Number: MX045 Product Type: Sealed AGM replacement battery Nominal Voltage: 12VDC Capacity: 7Ah Battery Chemistry: Absorbed Glass Mat, AGM Application: Gate operator battery backup and DC power storage Compatibility: Maximum Controls operators configured for local 12V, 7Ah AGM batteries Compatible Product Families: MAX PRO, MXG, MAX RHINO, and MAX arm operators using local 7Ah batteries Known Compatible Models: MAX 1200 FS PRO, MAX 1500 PRO, MAX 1700 FS PRO, MAX 2200 PRO, MAX F18 PRO, MXG 1800 FS, MXG 2300, MXG 2300-ST, MAX RHINO 4000 FS, MAX RHINO 5500, and compatible MAX arm control boxes using 7Ah batteries Battery Quantity: One battery; many operators require two batteries Function: Stores DC power for operator operation and battery backup Common Replacement Indicators: Reduced backup cycles, low battery voltage, battery input errors, failure to hold a charge, or slow battery-mode operation Battery Supplier: Supplied through Maximum Controls; actual battery manufacturer may vary Product Appearance: Brand, label, case design, and terminal appearance may change without notice Image Notice: Product image is representative and may not show the current battery supplied Condition: New replacement battery Verification Required: Confirm voltage, capacity, physical dimensions, terminal position, and required quantity before ordering Conclusion The Maximum Controls MX045 is the replacement 12V, 7Ah AGM battery for compatible MAX and MXG gate operators that use local 7Ah batteries. Because some operators use two local batteries while others support larger remote battery systems, confirm the existing battery specifications and required quantity before replacement. The battery brand and appearance may vary, but the supplied MX045 will meet the required 12V, 7Ah AGM specification.
