Before you order
Match the fitment checks on this page
Start with group size, CCA, and terminal layout so you do not buy the wrong battery first.
- • Verify group size, CCA, and terminal orientation.
- • Check whether your vehicle needs battery registration or a memory saver.
- • Keep the install order handy: negative off first, positive back on first.
Next step
If the symptom looks bigger than the battery
Charging and starter issues often show up next when a battery test is not the full story.
- • Use the vehicle hub to keep the exact year, make, and model context in view.
- • Compare the alternator and starter pages if the car still cranks slowly or not at all.

2018 Chevy Equinox Battery: Group 48 (H6/L3) AGM — 760 CCA
The 2018 Chevrolet Equinox (3rd generation) uses an AGM Group 48 (also called H6 or L3) battery mounted in the engine compartment on the driver side. Some trim levels with auto stop-start require an AGM battery; installing a standard flooded battery will cause premature failure and possible start-stop system errors.
OEM battery: ACDelco 48AGM (Group 48, 760 CCA, 900 CA, 120 min reserve) — AGM required on stop-start trims
Aftermarket fit: BCI Group 48 (L: 11.0 in, W: 6.9 in, H: 7.5 in); verify vent tube routing if equipped
Terminal type: SAE top-post with 10mm clamp bolts; positive on driver side, negative on passenger side
Torque battery terminal bolts to 62 in-lb (5.2 ft-lb / 7 N·m) — do not over-tighten
Save/restore radio presets and clock — battery disconnect resets BCM settings
No formal battery registration required, but driving 15+ minutes after install allows BCM to recalibrate charge rate
Inspect battery vent tube (if equipped) for cracks; route to atmosphere, not into engine bay

What the Pros Prefer: 2018 Chevrolet Equinox Battery Replacement Workflow
Terminal safety sequence, corrosion mitigation, and bracket security.
Negative Terminal Disconnection
Shop Tip:Tuck the detached negative cable aside so it cannot spring back and accidentally touch the battery negative post while you work.
Positive Cable & Hold-Down Bracket
Shop Tip:Hold-down j-bolts and brackets corrode rapidly from acid vapors. Spray threads with penetrating oil 5 minutes prior to turning to prevent snapped studs.
Terminal & Cable End Decontamination
Shop Tip:Scrape internal cable clamp surfaces until bright shiny metal shows. Even a microscopic layer of oxidation creates high electrical resistance and false starting failure.
Terminal Installation & Anti-Corrosion Seal
Shop Tip:Install the POSITIVE terminal first, then the NEGATIVE terminal last. Snug terminals until they cannot be twisted by hand, then coat exposed lead in protector spray.
