Product details

NAPA - NAPA Gel Deep Cycle Battery

NAPA batteries with special gelled electrolytes are game-changers when it comes to deep-cycle performance. These replacement automotive batteries have reached new limits with their impressive lifespan, high performance and maintenance-free appeal. Made for heavy-duty applications, the NAPA Gel Deep Cycle Battery is suitable for several applications, and it’s backed by our 3-Month Free Replacement Warranty.

Because your gel battery falls under the ‘deep-cycle’ category, it consistently delivers ongoing power capacity throughout an extended period, as opposed to traditional short bursts of power with minimal discharge cycles. It’s 100% maintenance-free, meaning there’s never a need to monitor fluid levels. Due to its spill-proof gel design, the NAPA Gel Deep Cycle Battery can be mounted in a variety of positions, making it an ideal option for something like a boat or an RV. The gel substance minimizes the risk of seepage, gassing and terminal corrosion. It also protects against harsh vibrations that can shorten your vehicle battery’s lifespan.

With a lower self-discharge rate, you’ll rest assured knowing your battery can still perform at optimal power whether or not it’s in constant use. Get reliable, steady power with no maintenance and a long shelf life when you install the NAPA Gel Deep Cycle Battery.
