Step-by-Step Instructions

Follow these steps carefully

Verify battery fitment and charging symptoms

The Integra takes a Group 47 (H5) — catalogs list AGM around 680 CCA. Buy a Group 47/H5 with CCA at or above the original and the same terminal layout. A charging warning that stays lit points at the alternator.

Make the vehicle safe and preserve settings when permitted

Park level, power fully off, key fob well away so the modules sleep first — disconnecting power while modules are awake causes phantom warning lights. Wear gloves and eye protection and keep metal tools off both posts; a swollen, cracked, or leaking case is a shop job.

🔧 Mechanic's note — Tom Becker

In my experience, That phantom-warning-lights warning is real on these cars — the modules talk to each other constantly. Keep the fob far away and let everything sleep a few minutes before you break the connection.

Disconnect the old battery

Remove battery cover if fitted. Loosen the negative (-) clamp first and tuck it aside, then the positive (+). Remove the hold-down bolt and lift the old Group 47 out with both hands, keeping it level. Photograph cable routing and terminal orientation first.

Compare and install the replacement

Compare the new Group 47 (H5) against old: footprint, height, terminals, CCA at or above the original. Clean the tray and cable ends. Lower it in, refit the hold-down snug, then reconnect positive first, negative second. Refit the battery cover.

🔧 Mechanic's note — Tom Becker

From my bay, An H5 that sits even slightly proud of the tray will keep the cover from fitting right. Test-fit before you connect anything — terminals that are mirrored or a case that's too tall mean the wrong battery.

Reset and verify operation

No registration step, but Acuras notice power interruption. Confirm a brisk crank, no warning lights, and 13.5-14.8 volts across the posts, engine running. Reset the clock and infotainment presets. If any warning light stays on or the car stalls, get the charging system diagnosed.

🔧 Mechanic's note — Tom Becker

Take it from me: If driver-assist warnings pop up right after the swap, don't panic — the cameras and radar recalibrate themselves after a few drives. Give it a day before you worry.

All Done!

Test your repair before closing everything up. If something doesn't work right, double-check your steps.

⚠️ Common Mistakes to Avoid

• Buying by appearance instead of group size, CCA, polarity, and hold-down fit
• Shorting the positive terminal to the body with a metal tool
• Lifting the battery by damaged terminals or leaving it unsecured
• Skipping battery registration, window/clock resets, or charging-system checks when required
• Assuming a new battery fixes a parasitic draw or charging fault

Tools You'll Need

⚠️ Safety First!

• Informational DIY. EZ Car Fix is not a shop.
• Verify the exact engine, battery group, polarity, and battery-management/registration requirements before disconnecting the old battery.
• Keep sparks, flames, and metal tools away from the battery; wear eye protection and gloves.
• Use the service procedure for memory retention, battery registration, and post-replacement calibration when equipped. This guide covers a conventional ICE 12-volt starting battery only; it is not an EV traction-battery procedure.
• Stop if the case is swollen, leaking, frozen, the terminals are badly damaged, or the cable is hot.
