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

This is a reliable, straightforward OEM-style replacement battery for garage door openers with backup systems. It does exactly what it’s supposed to do—no more, no less. If your opener uses a 4228-style battery, this is a safe, low-risk purchase. In practical terms, this battery isn’t flashy—but it’s dependable.

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.

So far so good! When the battery went out in our garage, we were able to get this fast. It has been in about a month and working great. It’s also great it was so much cheaper than Lift Master brand.

Just what I wanted. Fits perfectly for our Chamberlain garage door operator and it works great. The delivery was super quick, less than 12 hours. Would recommend to others.

Purchased to replace dead battery in my LiftMaster Garage Door opener. Before the old battery died completely I was getting sensor errors, the lights would not always come on. Turns out the dying battery was the issue. Replaced the dead battery with this one and all the other issues went away. 5 minute installation. Perfect!

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.

The Battery was an exact match to the one in my garage opener, it performed good still working every day really good Battery thanks.

easy replacement for my unit. charged quickly and works like a charm when the power goes out.

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

Excellent

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.

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

So far they are working
