Benefits
These 12V 7Ah SLA batteries deliver dependable performance and extended service life thanks to quality construction and sealed lead acid design. As a maintenance-free option, they eliminate the need to add water or perform routine electrolyte checks, which is ideal for installed gate systems where access may be limited. The consistent power output ensures smooth, consistent operation of your LiftMaster gate opener even under heavy usage or adverse conditions.
Because many gate openers use a pair of 12V batteries to form a 24V system, replacing both batteries at once with this 2-pack restores system balance and prevents premature discrepancies in charge and runtime. Beyond slide gate openers, these batteries are a solid choice for other applications requiring compact, reliable 12V power sources: small UPS systems, emergency power modules, alarm systems, and portable tools. Their long-lasting battery characteristics mean fewer replacements and reliable readiness when you need backup or continuous operation.
Choosing this pair gives you OEM-level quality and the convenience of replacing both batteries simultaneously, reducing installation time and ensuring matched capacity and performance across the system. The direct-fit design reduces the chance of fitment issues and simplifies installation for both DIYers and technicians.
Restore dependable 24V operation to your LiftMaster CSL24UL gate opener—add this 2-pack of 12V 7Ah high-performance replacement batteries to your cart now for a long-lasting battery solution.
