Installing Cr2032 Battery In Garage Door Opener

I just replaced a RAYOVAC 9V alkaline battery in the garage door opener keypad. It still worked, but was not 100% reliable. It survived at least 6 harsh Canadian winters and some really hot weather too. I only hope the new one I am using now will last just as long. Not for the cost, but I hate opening that battery compartment.

Because I was using one of these I don't have to replace my Garage Door Opener because it got fried!I just have to replace the cube for less than $.

[This review was collected as part of a promotion.] I just used it to our garage door opener and the batteries seem to hold fine. I received these batteries as the sample, but I think I will purchase this brand as a great value.

I bought this for garage door openers.

Works well with my D4! Also love that it uses AAA batteries and not some hard-to-find garage opener or hearing aid battery.

Useful in garage door openers and battery back-up in ac-powered clock/radios during power outages.

I run through a bunch of CR2032 batteries every couple of months. I like these because battery life has been good, and I can buy them at a reasonable price through B&H.

The RAYOVAC CR2032 Lithium Battery (2-Pack) contained two, count-em two CR2032 cells. Absolutely amazing!!. These were purchased as spares, so I have not measured their voltage yet. Presumably, they will produce the rated 3 Volts and will last for 190 to 240 mAh. They are 20 mm in diameter, shiny and light weight and most likely contains some lithium & manganese dioxide so are technically a LiMn02 cells. FYI: They can explode if heated to more than 80 deg. C.

I have 3. One in my garage one in my foyer(vaulted) one in our bedroom. Working outside with garage door open is fantastic.

The cameras are wonderful, they are crystal clear and we are still installing the 5th camera on the garage. My Sons best friend is installing and it so far has taken a day and a half. We have our fence lines set up but need to do all the fine tuning on the rest of the settings. But we have had prowlers so being able to be alerted and see will be amazing. I will update when finished.
