How Many Amp Hours Are in a Group 24 Deep Cycle Battery?

How Can You Maximize the Amp Hour Performance of a Group 24 Battery?

Avoiding discharges below 50% depth of discharge (DoD) is critical because deeper cycles accelerate plate degradation in lead-acid batteries. For example, discharging to 70% DoD can reduce a battery’s cycle life by half compared to 50% DoD. Temperature-compensated chargers adjust voltage based on ambient conditions—lowering charge voltage in high heat to prevent gassing and increasing it in cold to ensure full absorption. This prevents undercharging in winter and overcharging in summer, both of which erode capacity.

What Is a Group Size 24 Battery?

Flooded batteries benefit from monthly equalization charges—a controlled overcharge that mixes electrolyte and breaks up sulfate crystals. This process requires disconnecting loads and charging at 15–16 volts for 2–4 hours. AGM batteries, however, should never be equalized due to sealed construction. During storage, maintain a 70–80% charge and check voltage every 3 months. Storing below 40% charge risks permanent sulfation, while 100% charge increases self-discharge stress.

What Are Common Applications for a Group 24 Deep Cycle Battery?

In marine environments, these batteries power trolling motors for 4–8 hours depending on thrust settings. A 24V system using two Group 24 batteries can run a 55 lb thrust motor at medium speed for 6 hours before reaching 50% DoD. They also support navigation systems, livewell pumps, and stereos, with saltwater applications requiring corrosion-resistant terminals.

For RVs, a single 100Ah AGM battery can run a 12V refrigerator (3A draw) for 16 hours while maintaining LED lights and a water pump. When paired with a 2000W inverter, it can briefly power microwaves or coffee makers, though sustained high-wattage use demands lithium alternatives. In solar setups, Group 24 batteries store energy from 300W panels, providing 2–3 kWh daily for lighting, small appliances, and device charging. Their compact size suits cabins and sheds where space limits bank size.

Q: Can a Group 24 battery run a 1000W inverter?

A: A 100Ah battery can support a 1000W inverter for ~30 minutes at full load (assuming 50% DoD), but continuous use requires larger banks or parallel configurations.

Q: How long does a Group 24 battery last on a single charge?

A: At a 5A draw, a 100Ah battery lasts ~20 hours. Halve runtime for 10A loads due to Peukert’s effect.

Q: Is a Group 24 battery suitable for solar storage?

A: Yes, especially AGM models, which handle partial charging better. Pair with a 200W solar panel for daily recharging.

“Group 24 batteries strike a balance between size and capacity, but users often underestimate thermal and load impacts. AGM is worth the premium for cyclic applications—its sealed design and higher efficiency pay off in harsh environments. Always oversize your bank by 20% to account for Peukert losses and aging.”
