C4 Rayovac
I bought this 4 pack battery in early December 2025. I went to use it in mid January 2026. All of the batteries leaked and are corroded. I am not happy with this product.

Lasts a lifetime
These batteries last a long time. I haven’t had to change them in my radio for a while! The packaging is sturdy, and doesn’t have too much plastic, and it’s easily recyclable.

Great
Great batteries. Last very long and easily available from all stores. However i feel they run out a bit quicker than other brands. Overall good!

Value for money
Excellent packaging, compatibility and durability is definitely value for money. I am not sure about the environmental impact since i am not a subject matter expert.

These get the job done
Ok batteries they just die kinda fast but they are on the cheaper side of batteries . If on a budget and need something to last then these are good for that

Good
Well, they’re basically your standard battery and they work to power up your devices. I wouldn’t say there’s anything super special about them, but they do the job.

Rayvoc High Energy C Batteries 4pk
I purchased the Rayovac batteries to place in an LED candle. My previous Rayovac battery lasted almost 5 months. Good batteries!

Great performance.
We’ve been buying Rayovac batteries for a few years now because we started noticing our usual brand was starting to leak acid in all of our devices. We decided to try them and we like them. No leaking. No rusted metals. They seem to last a decent amount of time too. I’m pleased with the performance of these batteries.

Work just good as Duracell
I always use Duracell but these works just as good and are a little cheaper. But are very comparable. They come in packs of 4 and 8 as well. These are my go to batteries.

dd 2016 DEC!!!
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.

Reliable and Ready Ra
[This review was collected as part of a promotion.] I received a free package of Rayovac High Enegry 9v Batteries to review, I use these Batteries in my alarm clock because I live in a part of the country that has a lot of storms we experience a lot of Power outages so my appliances need a Backup Power socure that is reliable and the cheaper off brand Batteries don't work and are reliable like Rayovac, the switch always turns on.

These are great
[This review was collected as part of a promotion.] I don’t use as many of these as I once did, but I’m so happy that they’re still around. These come from a trusted brand and work great! I used these on my smoke detector and they fit great.

Log lasting
[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.

Keeps the beep away
[This review was collected as part of a promotion.] We use these for our smoke detectors. Lived in this house for three years, and the smoke detectors expired before the batteries quit working. So of course, this was our first choice for batteries when we loaded the new ones.

Great for effect pedals!
[This review was collected as part of a promotion.] I play bass guitar and LOVE effect pedals, normally I use a power supply for my pedals, but if you use effects you know that some pedals work, and sound better with batteries. That’s where these rayovac high energy 9v batteries come into play. I definitely don’t want to be fumbling around with dead batteries on stage, and these last longer than most of the more expensive ones. Another great product from rayovac!

Long lasting
[This review was collected as part of a promotion.] I put these in my smoke detectors because I know they last a long time and I can rely on them laying the time I need before I replace them again. My family’s safety relies on their ability to alert us to a fire or smoke so I put s a lot of confidence in their lasting till I change them every 6 months.

Batteries are essential
[This review was collected as part of a promotion.] I always like to change my batteries in my smoke alarm on 5/5 and 11/5 this is easy to remember and it keeps us safe. The 9v is easy to install and makes us feel secure and safe.
