#1 · Best Overall

1. ACDelco Gold 48AGM

• Dimensions: 7.5"D x 11.9"W x 7.6"H
• Weight: 45.5 lb
• Voltage: 12 V

Best for: Group 48 AGM replacement.

Why it ranks #1: Its BCI Group 48 designation and stated truck compatibility align closely with the target use, and it lists a 36-month free-replacement/limited warranty.

Its Group 48 AGM construction pairs high-density negative paste with a Silver Calcium alloy, giving a truck owner a battery engineered for cycling performance and extended battery life.

High-density negative paste and the enhanced-life alloy target performance and cycle life, while the envelope separator’s puncture-resistant back supports acid circulation and helps prevent shorts. ACDelco also describes its AGM design as spill-proof, with electrolyte held in the glass mat. At 45.5 pounds and 11.9 by 7.5 by 7.6 inches, consider lifting and tray dimensions before installation.

Skip it if you need documented cold-cranking amps; the Goodyear 48-H6-AGM lists 760 CCA, while this listing supplies no CCA figure.

For a Silverado owner whose required replacement is Group 48, this ACDelco AGM combines truck listing with cycle-life-focused construction. Treat it as a size-specific candidate, not a universal fit; verify the truck’s required group and terminal arrangement.

• Dimensions: 6.88"D x 10"W x 7.81"H
• Weight: 38.8 lb
• Voltage: 12 V

Best for: Dual-terminal AGM starting battery.

Why it ranks #6: Its dual SAE and GM posts and 800 CCA offer useful details, but its 34/78 size is not the Group 48 match ranked higher.

• Weight: 51.6 lb
• Voltage: 12 V

Best for: Group 94R AGM candidate.

Why it ranks #7: It has AGM construction and a 36-month free-replacement/limited warranty, but its Group 94R designation does not match the Group 48 candidates.
