Garage Door Remote Battery Cr2032

I bought this for garage door openers.

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

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.

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.

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 $.

Outstanding remote for T8I. Big complaint about the T8I dose not come with removable battery door for battery grip. No grips available forT8I. Remote works great.

[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.

[This review was collected as part of a promotion.] These batteries have been great for my garage door. I’ve had an issue where my garage pad kept draining all the batteries I’ve used until I put these in. So far it’s been a month and the garage still works well and I’ve had no issues with the battery life! Overall, I’m very pleased.
