Continental 34/78-P Performance 12V SLI Battery

Continental 34/78-P Performance 12V SLI Battery

Advantage Batteries supplies the Continental 34/78-P Performance as a factory-activated 12-volt SLI (Starting, Lighting, Ignition) replacement for vehicles that specify BCI Group 34, Group 78, or dual Group 34/78. This is a flooded lead-acid automotive starter, not a deep-cycle or AGM pack. It is sold for cranking duty: 550 cold cranking amps in a dual-group case so one SKU covers platforms that accept either group size.

Use this SKU when the application calls for Group 34, Group 78, or 34/78, 12 volts, and flooded SLI chemistry. Confirm group size, tray dimensions, hold-down style, and cable reach before purchase. Dual-group listing does not mean every Group 34 or Group 78 vehicle is a drop-in. If the vehicle lists a different BCI group, this unit will not be a correct fit.

Shop the Continental 34/78-P online or pick it up at a qualifying Advantage Batteries location.

Technical specifications

Values below are from Continental Battery Systems for SKU 34/78-P. Figures not published on that product page are omitted.

Warranty

Continental backs the 34/78-P Performance with an 18-month manufacturer warranty. That term is the one published on the Continental 34/78-P product page. It is not a 24-month Supreme-line term and not an Advantage Batteries house warranty unless stated separately at checkout.

Warranty coverage follows the manufacturer’s policy: defects in materials and workmanship for the published period when the battery is used as an automotive SLI unit in a matching Group 34, 78, or 34/78 application. Abuse, deep discharge, incorrect group size, or use outside SLI duty typically voids coverage. Keep the purchase record. File a claim through Advantage Batteries or Continental per the policy in effect at sale.

Fitment and install notes

• Match BCI Group 34, Group 78, or 34/78 on the existing battery or in the vehicle’s battery spec. Dual-group fitment still requires the tray, hold-down, and cables to line up with this case.
• Measure the tray against 10.25 × 6.81 × 7.88 in before ordering.
• Do not assume a Group 34-only or Group 78-only battery from another brand uses the same posts or height. Check the existing unit.
• This is a flooded battery. Keep it upright. Do not mount on its side.
• Factory-activated means it ships wet and charged for install; still verify open-circuit voltage and charge if it has sat.
• After install, seat the hold-down and confirm cable polarity before the first start.
