2011 CR-V 12V Battery
Loosen "-" Negative Terminal
Pull Terminal Off Post
This automotive maintenance tutorial was specifically written to assist owners of the third generation (2007, 2008, 2009, 2010 & 2011) Honda CR-V in removing a weak or dead 12V automotive battery from the engine bay and installing a new one in its place.

Owners of other Honda or Acura vehicles such as the Pilot, Insight, CR-Z, Accord, Civic, Fit, Crosstour, Odyssey, Ridgeline, TSX, ILX, TLX, TL, RLX, RDX and MDX may also find these DIY instructions to be helpful.

A few compatible replacement Group Size 51R batteries with their part numbers are as follows: EverStart MAXX-51R (at Walmart), AutoCraft # 51R-2, Optima 8073-167 D51R,, ProStart 51R500PS, Bosch 51R450B, Panasonic 55B24L S-MF, Exide Edge FP-AGM51R and Honda 31500-SR3-A07 or 31500-SR1-100M.

The tools needed to replace the battery include a deep well 10mm socket with a 1/4" drive ratchet (or a standard 10mm wrench) and a pair of needle nose pliers.

Tuck Negative Cable Aside
PullWire Harness Off Bar
Battery Clamp Bar Exposed
The first two steps are to open the hood and then move to the right (driver) side of the engine bay.

For extra safety, I'd recommend wearing gloves and protective eyewear.

The 12V car battery is located just behind the driver side headlight and in front of the engine air box.

Loosen the nut on the "-" negative terminal first by turning it counterclockwise with a 10mm socket and ratcheting wrench.

Pull the terminal straight off the battery post. Wrap the terminal in a small towel and tuck it away to the side to prevent accidental contact.

Pull off the black plastic cap that holds the wire harness cable tie in place on the rear battery clamp bar.

Loosen Rear 10mm Nut
Loosen Counterclockwise
Remove Battery Hold Down
Loosen the nut on the rear battery hold-down bar by turning it counterclockwise with a deep well 10mm socket and ratcheting wrench. (Or use a standard 10mm hand wrench.)

Then loosen the nut on the front battery hold down bar.

Only loosen the nuts a few turns at a time until the metal hooks at the bottom of the "J" bolts can be removed from their mounting brackets.

Carefully lift the battery hold down clamp off the top of the battery while avoiding contact with the battery posts.

Hold Down Clamp Removed
Lift Off Positive Cover
Loosen "+" 10mm Nut
Pull open the hinged red plastic cover on the "+" positive battery terminal.

Loosen the nut by turning it counterclockwise with the 10mm socket and ratcheting wrench.

Lift Off Positive Terminal
Lift Out Battery Box
Plastic Battery Cover Removed
Lift the positive terminal straight off the battery post, close the plastic cover and tuck it away on the side of the battery.

Pull the plastic protective battery box straight out of the engine bay and set it aside in a safe place.


Pull Out Old 12V Battery
Panasonic # 55B24L S-MF
Group Size 51R Battery
Carefully lift the old battery off the tray and out of the engine bay while avoiding contact with the exposed electrical posts.

The OEM battery in this 2011 CR-V was a Panasonic # 55B24L S-MF which is also known as the YUASA 55B24L S-MF, Honda # 31500-SR3-A07 or 31500-SR1-100M.

Any new Group Size 51R battery should fit in the 07-11 CR-V but please consult with an auto parts store or a manufacturer's online application guide website before purchasing a new one.

Be sure to bring the old battery with you to the store to avoid having to pay a "core" or "disposal" fee. The auto parts store or Walmart will have the old battery properly recycled.

Plastic Battery Tray
Lower In New Battery
Replace Plastic Battery Case
Clean off any debris on the plastic battery tray to make sure that the new battery will rest level and not sit at an angle.

Lower the new battery down in to the engine bay with the "+" positive post on the left side and the "-" negative post on the right (driver) side.

Lower the plastic battery box down over the new battery.

If you purchased a Group Size 51R battery, the plastic box should fit over it.

If you've had a problem with corrosion (white or blue powder) building up on the terminals or the battery posts, consider installing some felt anti-corrosion washers over the battery posts.

Push On "+" Terminal
Tighten 10mm Nut Clockwise
Snap Closed "+" Cover
Push the "+" positive terminal (red plastic cover) on to the positive battery post.

Tighten the 10mm nut on the terminal in the clockwise direction until it is snug.

Do not over tighten the terminal nut to prevent from damaging the battery post.

Close the red plastic cover over the positive terminal.

Lower Battery Clamp Bar
Insert Bar Hook In Hole
Front Hook In Bracket
Carefully lower the battery hold-down bar over the center of the new battery while avoiding contact with the battery posts.

Guide the hooks at the bottom of the two "J" bolts in to the corresponding holes at the front and rear of the battery tray.

Tighten Rear 10mm Nut
Tighten Nut Clockwise
Push On Wire Harness
Tighten the two 10mm nuts on the battery clamp by turning them in the clockwise direction until they are snug.

Make sure that the battery is securely held in place. If the battery can be moved on the tray, tighten the two nuts a few more turns.

Do not over tighten the battery hold down bar to prevent from damaging the plastic top on the battery.

Push the black plastic cap back in place on the rear hold-down bar to secure the wire harness in place.

Push On Negative Terminal
Tighten 10mm Nut Clockwise
12V Battery Replaced
Carefully push the "-" negative terminal on to the negative battery post on the right (driver) side of the battery.

Tighten the 10mm nut in the clockwise direction until it is snug.

Check that the new battery works properly by starting the engine.

Be sure to adjust the time on the clock and re-program your favorite radio stations to the preset buttons before driving.

If the radio says "ENTER CODE" on the display, check out my Honda Radio Code Retrieval & Entry Guide.

Be sure to record the battery change in your vehicle's service records.
