Chevrolet Silverado 1500 battery: common questions
What size battery does a Chevrolet Silverado 1500 take?
- BCI group 48 (H6). Group size is a physical dimension and terminal-position standard, so a battery from a different group may not clamp down or may put the terminals on the wrong side.
Does the Chevrolet Silverado 1500 need an AGM battery?
- The factory battery is an AGM type. Match the type when you replace it.
Where is the battery on a Chevrolet Silverado 1500?
- Engine bay, driver side.
Does a Chevrolet Silverado 1500 need the battery registered after replacement?
- Trucks with auto stop/start (most retail configurations) use a Group 48/H6 AGM (~70 Ah, 760 CCA) and should be replaced with AGM only; fleet trucks without stop/start use a flooded H6. Some diesels add a second (auxiliary) battery. No scan-tool registration required, but disconnect procedures apply. See the manual.
