-
Weight: 50–60 lbs
-
Compact design, ideal for space-limited installations.
-
-
Group 27:
-
Size: ~12.1" (L) x 6.8" (W) x 8.9" (H)
-
Weight: 60–70 lbs
-
Larger than Group 24, offering higher capacity without excessive bulk.
-
-
-
Size: ~13" (L) x 6.8" (W) x 9.4" (H)
-
Weight: 70–80 lbs
-
Largest in this series, designed for heavy-duty applications.
-
② Capacity and Performance
-
Group 24:
-
Ah (Amp-Hour): 70–85 Ah
-
Reserve Capacity (RC): 120–160 minutes
-
Best for light to moderate power needs (e.g., small RVs, trolling motors).
-
-
Group 27:
-
Ah: 85–105 Ah
-
RC: 160–190 minutes
-
Balances capacity and size, suited for medium-duty use (e.g., mid-sized boats, solar backup).
-
-
Group 31:
-
Ah: 100–125 Ah
-
RC: 200–240 minutes
-
Highest capacity, ideal for high-demand systems (e.g., large RVs, industrial equipment).
-
③ Durability and Lifespan
-
Group 24 batteries typically last 3–5 years with proper maintenance.
-
Group 27 and 31 models, due to thicker plates and robust construction, often exceed 5–7 years.
2. Application Scenarios
Group 24 Battery
-
Primary Uses:
-
Small recreational vehicles (pop-up campers, teardrop trailers).
-
Kayak or canoe trolling motors.
-
Backup power for small solar setups.
-
-
Limitations: Less suitable for high-energy appliances like air conditioners.
Group 27 Battery
