The DC24-AGM Marine RV Battery is a 12V deep-cycle Absorbent Glass Mat (AGM) battery optimized for marine and recreational vehicles. Designed for durability, it offers 80–100Ah capacity and withstands deep discharges (up to 50% DoD), with spill-proof construction and vibration resistance. Ideal for powering trolling motors, RV appliances, and off-grid setups, it charges via 3-stage (14.4–14.8V) protocols to prevent sulfation.

What defines the DC24-AGM battery’s design?
This AGM battery combines dual-purpose starting/deep-cycle capabilities with spill-proof VRLA (Valve-Regulated Lead-Acid) construction. Its fiberglass mat separators absorb electrolyte, enabling stable operation at 30°–45° tilt angles—crucial for boats navigating rough waters. Pro Tip: Regularly check terminal voltage (12.6V+ indicates full charge) using a digital multimeter to avoid underperformance.

Unlike flooded batteries, the DC24-AGM eliminates electrolyte refilling and reduces gassing. Its lead-calcium grids minimize corrosion, achieving 500–800 cycles at 50% DoD. For example, a 100Ah DC24-AGM can power a 50W RV refrigerator for ~24 hours. But what about extreme temperatures? Built-in AGM technology performs reliably from -15°C to 50°C, unlike lithium-ion, which struggles below freezing. A key trade-off: AGMs weigh 25–35% more than lithium but cost 60% less upfront.

|---|---|---|---|
| Maintenance | None | High (refill water) | None |
| Cycle Life | 500–800 | 300–500 | 600–900 |
| Cost per Ah | $1.50 | $1.00 | $2.00 |
How does DC24-AGM compare to lithium-ion for marine/RV use?
The DC24-AGM trades lower energy density for cost efficiency and safety, making it ideal for budget-conscious users. While lithium batteries offer 2,000+ cycles, AGMs avoid thermal runaway risks—a critical factor in enclosed RV compartments.

Lithium-ion excels in weight (∼50% lighter) and depth of discharge (80%+ DoD), but AGMs handle overcharging better. For instance, a 100Ah lithium battery can discharge to 20% SOC (State of Charge) without damage, whereas AGMs degrade below 50% SOC. Pro Tip: Use temperature-compensated chargers for AGMs in variable climates. While lithium thrives in solar setups, AGMs are better suited for alternator charging systems common in boats and RVs.

FAQs
Yes—AGMs are direct drop-ins but require voltage-regulated chargers. Flooded systems often use higher absorption voltages (14.8V+), which can dry out AGM cells over time.
How Long Will an EZGO Golf Cart Last?How long does a DC24-AGM last on a single charge?
Depends on load: A 100Ah model running a 10A trolling motor lasts ∼5 hours at 50% DoD. Always size batteries to 1.5x your estimated energy needs.
Is the DC24-AGM safe for indoor RV use?
Absolutely—AGM batteries emit minimal hydrogen, eliminating explosion risks. However, ensure proper ventilation and avoid mounting near heat sources.
