## Description

Product Description desertcart Basics 8 Pack 9 Volt Performance All-Purpose Alkaline Batteries, 5-Year Shelf Life, Easy to Open Value Pack From the Manufacturer desertcart Basics

Review: desertcart Basics 8-Pack 9V Alkaline Battery - The desertcart Basics 8-Pack 9V Alkaline Batteries are a reliable and cost-effective choice for powering essential household devices such as smoke and carbon monoxide detectors, audio equipment, and other electronics. These batteries performed great right out of the package and offered consistent, dependable power. The size is standard and fits perfectly in compatible devices, and they deliver accurate, steady performance when reliability matters most. Overall, this is a great deal and a smart purchase for anyone looking to stock up on dependable 9V batteries. Pros: High quality and dependable performance, Great price and value, Worth the money, Easy to install and use Cons: None Overall, these batteries provide excellent performance at a budget-friendly price, making them a great option for everyday household needs.
Review: Why pay double? Reliable power for all my electronics at a fraction of the cost - I used to only buy the "big name" brands for my household batteries, especially for critical things like smoke detectors. However, after trying this desertcart Basics 4-Pack of 9V Alkaline Batteries, I'm officially a convert. They offer the exact same performance without the "brand name" markup. 1. High Performance Right Out of the Box I tested each of these with a multimeter as soon as they arrived, and they all registered at a consistent 9.5V to 9.6V. They aren't sitting on a shelf losing power; they arrive fresh and ready to go. I’ve used them in everything from high-drain RC toys to my digital multimeter and acoustic-electric guitar, and they haven't skipped a beat. 2. The 5-Year Shelf Life is Real The 5-year leak-free shelf life is a huge selling point for me. I like to keep a few extras in the "junk drawer" for when that dreaded low-battery chirp happens at 2:00 AM. Knowing these will still be at full strength two or three years from now gives me total peace of mind. It makes stocking up for emergencies or power outages much more practical. 3. Perfect for Smoke & CO Detectors If you have multiple smoke or carbon monoxide detectors in your house, the cost of replacing batteries every year adds up fast. These fit perfectly in the battery compartments—no struggling with tight fits or weird dimensions. They provide steady, reliable power that lasts just as long as the expensive copper-top alternatives I used to buy. 4. Frustration-Free Packaging I actually appreciate the Certified Frustration-Free Packaging. There’s no sharp plastic clamshell to hack through with scissors. The box is easy to open, and it doubles as a neat little storage container for the remaining batteries so they don't roll around and short out against each other. Pros: Incredible Value: You get four batteries for the price of two from most other brands. Reliable Longevity: Lasts just as long as premium brands in low-to-mid drain devices. Leak-Proof Design: 5-year shelf life ensures they are ready when you need them. Standard Fit: Fits perfectly in smoke detectors, garage door openers, and guitar pedals. Cons: These are single-use alkaline batteries, so they aren't rechargeable. Not intended for extremely high-drain industrial tools (stick to lithium for those). Final Verdict: There is no reason to spend twice as much on "premium" brands for everyday household items. These desertcart Basics 9V batteries are reliable, long-lasting, and arguably the best value on the market. I’ll be buying these exclusively from now on

## Questions & Answers

**Q: Can anyone please compare the size of these batteries to the size of standard 9 volts? Are they the same size as standard batteries or longer?**
A: Amazon 9V batteries received in November 2022 were not larger than a Duracell 9V in any dimension. Carefully measured. Many earlier answers say they are larger, but apparently that problem has been resolved.

**Q: Will these fit the standard fire/smoke alarms?  comments say that amazon batteries are longer than others which are hard enough to install..thanks**
A: In my review (http://www.amazon.com/review/RNAU5AWNID6IA/ref=cm_cr_rdp_perm) I provided detailed measurements and pictures of the batteries and side by side comparisons.The AmazonBasics and a Utilitech "heavy duty" battery, neither of which fit my CO detector, were both right about 0.6mm longer and 0.6mm fatter than a standard Duracell battery which did fit my CO detector. It seems these are the "big" 9v's (Possibly "Heavy duty"?). They do fit in my smoke detectors, but it really comes down to whether you have a cramped battery compartment or one that does weird things to connect the battery. You should probably pass if that's the case or if you've had issues installing your current batteries.

**Q: How much ampere for a battery ?**
A: rightbattery has measured them at 481 mAh for a 50 mA (light) load, which is second only to Ikea's - they have test results for a dozen different 9-volts there.

**Q: I need these for a rental property. The city requires that they have expiration dates listed on the battery themselves. Can anyone confirm?**
A: The date is very small on the bottom of the battery.  Just received a box of 8, expiration 02/2025.
