A Group Size 24 battery is a standardized automotive battery defined by its physical dimensions (10.25″ x 6.8″ x 8.9″) and terminal placement. It typically provides 70-85 Ah capacity and 600-800 CCA, ideal for mid-sized vehicles. It works by converting chemical energy into electrical energy through lead plates and sulfuric acid electrolyte, powering starters, electronics, and accessories efficiently.

In marine environments, Group 24 batteries power trolling motors, fishfinders, and onboard lighting systems. Their spill-proof AGM variants are preferred for boats due to vibration resistance and safety. For RVs, these batteries efficiently run lighting, refrigerators, and inverters during off-grid camping. Solar installations often use multiple Group 24 units wired in parallel to create affordable 24V or 48V systems, with AGM models handling daily charge/discharge cycles better than traditional flooded batteries. Hybrid vehicles also utilize this size for auxiliary systems, leveraging its compact design to fit tight engine compartments without compromising power reserves.
What Maintenance Practices Extend a Group Size 24 Battery’s Lifespan?
1. Clean terminals monthly with baking soda/water to prevent corrosion.
2. Maintain electrolyte levels (flooded types) using distilled water.
3. Avoid deep discharges below 50% SOC.
4. Use a smart charger to prevent sulfation.
5. Store at 60°F in dry conditions if unused. AGM variants require less maintenance but benefit from voltage monitoring.
For flooded batteries, check electrolyte levels every 2-3 months, topping up only with distilled water to avoid mineral contamination. Invest in a digital hydrometer to measure specific gravity – values below 1.225 indicate needed charging. AGM users should perform voltage checks monthly; sustained readings below 12.4V require immediate recharging. All types benefit from annual load testing to assess capacity loss. Apply anti-corrosion gel to terminals after cleaning, and ensure battery trays are secure to minimize vibration damage. In colder climates, use insulation blankets to reduce cranking strain during winter starts.
| Maintenance Task | Frequency | Tools Required |
|---|---|---|
| Terminal Cleaning | Monthly | Baking soda, wire brush |
| Voltage Check | Bi-weekly | Multimeter |
| Load Testing | Annually | Battery load tester |

Advancements in Lithium-Ion Group 24 Batteries
Recent developments in lithium-ion technology have led to Group 24 batteries offering enhanced durability and longevity. These batteries are less susceptible to damage from vibration and deep discharges compared to traditional flooded lead-acid batteries, making them suitable for applications requiring sustained power over extended periods.
FAQs
- Can a Group 24 Battery Power a 1,500W Inverter?
- Yes, but runtime depends on Ah. A 85Ah battery (1,020Wh) at 85% efficiency runs a 1,500W inverter for ~35 minutes at full load. Use lithium variants for sustained high draws.
- Is Group 24 Interchangeable With Group 35?
- No. Group 35 (9.06″ x 6.88″ x 8.43″) has different dimensions and terminal positions. Adapters may force incorrect mounting, risking vibration damage.
- How Long Does a Group 24 Battery Last in Storage?
- Flooded: 3-6 months before needing recharge. AGM: 6-12 months due to lower self-discharge (1-3%/month). Store at 50% SOC, 60°F, disconnected from devices.
