/ LiftMaster / Craftsman 4228 Replacement Battery for Battery Backup Equipped Garage Door Openers (Packaging May Vary) Medium

This worked perfectly with my Chamberlain garage door opener. Installation was very easy. I used a Phillips screwdriver to remove the screw on the battery cover plate on the left side of the opener, unplugged the black wire and red wire, inserted the new battery, then reconnected the red wire and black wire. It works perfectly. I did need to press the outlet reset button on my garage wall, but that is due to how my house is wired and likely will not be necessary for most homes. The sticker date on the replacement battery shows 10/13/2025 and today’s date is 12/21/2025, so the battery is very fresh. For the price and quality, this is a no brainer purchase. I ordered it last night and it arrived by 8am the next morning. It appears older reviews had issues, but they likely purchased earlier versions. Recent reviews and my experience have been excellent. This battery is identical to the OEM version and even arrived in an OEM Chamberlain box. Very happy I did not need to call a repair technician and saved money by fixing this myself.

Fits perfectly and came fully charged and working.

Very easy to install, works well,perfect for our unit

I bought this battery to replace the original that lasted 6 years. It was easy to install and was a great fit.

My electric garage door opener battery was about 5 years old & failed from old age. This is an exact replacement. Works fine; no problems. Happy customer.

Ready and easy to install. Fit my device like it said it would. Very happy with product. Would encourage others to buy if needing this product.

Great price and was easy install has worked perfect for months now

We have a Liftmaster garage door opener. The back up battery went out -- I didn't even realize that it had a backup. Anyhow, this exact same battery made by the exact same company is ridiculously expensive. This one is the exact same at less than half the price! I looked at getting a no-name battery that had the same specs and was even more affordable, but that the negative and positive connections on these Liftmaster/Chamberlain/Craftsman openers are different sizes. Probably designed that way to make sure folks don't install it backwards. Paying a little more for the Chamberlain branded battery is worth it to make sure the connections are solid. I installed in in less than 10 minutes, including getting the ladder out and set up.

Perfect replacement every time. We have now purchased 3 units and satisfied every time.

Item as described. Installation was very easy. I recommend this product.

Ordered this as the original battery in our Chamberlain garage door opener was no longer charging and keep hearing a loud auidble beep until the old one was removed. I was pleasantly surprised to discover upon opening the shipping box it's a replacement of the original battery. The old battery is on the right and new one on the left in the photo that shows both side by side. It's literally a 5 minute job to reopen the battery compartment to reconnect the wires and close it back up using a Phillips screwdriver. A glance at the control panel shows the battery was about 50% charged. This seems to be a good deal having gotten it at a reduced price around $54. The battery sticker indicates it was manufactured May 26, 2023. Hopefully this new battery will provide about 6-7 years of similar to the original. Time will tell but glad this battery is an actual OEM replacement and not a generic knock-off.

It was nice the battery on Amazon. It works well.

So far they are working
