My owner's manual called for replacement battery part # 41A6357-1. This one looked exactly right though and it was about $10 cheaper than I could find the other one. I called Chamberlain and they said it was the same thing. I went ahead and ordered the 4228 and it fits and works perfectly. Very simple to do yourself (though the manual says to call service if the red light stays on and it beeps every 30 seconds). Glad I didn't call service it would have cost a lot more and this only took me about three minutes to replace and it fixed the problem! Chamberlain 4228 EverCharge Standby Power System Replacement Battery
I purchased this battery replacement for the Chamberlain Whisper Drive Plus 3/4 HPS model# 248754. The manual and Chamberlain's website called for purchasing part# 41A6357-1.
The Chamberlain website was about the same price (just slightly more), but the shipping was $8.63 for ground (5-10 business days) and $29.83 for air (3-5 business days).
The annoying beep every 20-30 seconds was enough to pay the $30 for air shipping, but I had to wait another 3-5 business days.
I read a couple of reviews stating that this battery was successfully used to replace the 41A6357-1 battery type. The connectors on this battery is slightly different than the original manufacturer battery as it did not have wires connected to the battery and only had the clips. The wires on the original manufacturer battery allowed for an easier time to remove the battery. I could tell that by inserting this battery into the unit, it would be difficult to pull it out the next time I have to replace it. Furthermore, this battery fit just a tad bit more snug than the OEM one.
So, before pushing this battery in all the way, I removed three screws that held the side panel on the side that the battery is on. Once that panel is removed, it was VERY easy to push in and out the battery replacement. I didn't want to push this battery in all the way with the risk that I'll never be able to get it back out.
I'd buy it here from Amazon because it was about the same price as the Chamberlain website, saved $30 in shipping, and I received it two days after ordering because of Amazon Prime!
The slight inconvenience is the fact that the next time I replace this battery, I'll have to spend an extra 5-7 minutes removing and putting back the panel to remove the battery.
Amazon had the best price for this battery for my garage door opener. The only other place that had this for sale was Home Depot (and they did not have it in stock and had to be ordered online) and was $10.00 higher than Amazon, plus taxes and shipping costs. Amazon didn't charge me tax or shipping. So an overall savings of about $20 dollars over Home Depot online. Thanks Amazon!!
FYI - this is also the correct battery for the opener sold at home depot under part #HD900D. Makes it stop beeping.
If you google part# SA1245 you can probably score one of these for under $20 shipped. No complaints about this one though - just an FYI if you haven't ordered yet. Chamberlain just sticks their sticker over the manufacturer's label.
Our Chamberlain battery started beeping to be replaced, but battery #41A6357-1 from Chamberlain was going to cost $55 and take at least 7 days to arrive. The 4228 worked great and was $15 cheaper. Awesome!
My battery went out after right at 3 years. Ironically so did my neighbors (same model, etc). The beeping was unbelievably horrible...The battery makes it stop. I don't know what else to say other than i can't believe you can't stop the beeping without a battery.
Backup battery not needed for operation. Just remove old battery to stop beeping. If you have a power failure go in the front door of your house and into the garage and pull the emergency red cord to disengage the motor and raise the door manually. I never had occasion to use the battery backup feature once during the life of the battery which was approx. three years so decided the battery backup was a waste of money.
The original standby battery gave up the ghost. After verifying with Chamberlain that the Amazon battery was identical to the original I purchased it. Installation was a breeze. Unfortunately, nobody at Chamberlain told me that when the battery is removed and the power to the opener pulled that the opener loses it's up/down end points and closing force adjustments. It's not in the instructions either. Once that was done we were good to go.
We purchased our garage door opener from Lowes and had them install it - less than two years ago - when the battery back up went bad (the chirping will drive you nuts!!) we found that they didn't sell this part - found it on Amazon - received it in record time and no problem since then - really glad to have it too - we've had numerous power outages due to storms!'
