Let me tell you, these Energizer EN22 Industrial Alkaline Batteries are the real deal. I've been using them in everything from smoke alarms to my golf range finder, and they just keep going and going.

The best part? These bad boys last FOREVER. I've got them in my condo's stair lift remotes for over a year now (way past the recommended replacement time) and they're still showing strong on my battery tester. That's some serious staying power!

Price-wise, you can't beat it. I saved about 30% compared to buying name-brand batteries at big box stores. The simple cardboard packaging might not win any beauty contests, but who cares when you're getting this much value?

One thing to watch - check those expiration dates! Some folks reported getting older stock (though mine were fresh with a 2026 expiry). Even the "older" ones performed perfectly in smoke detectors though.

Pro tip: Buy in bulk when you need to replace multiple batteries around the house. These are perfect for smoke alarms, water leak detectors, and other safety devices where you don't want to skimp on power.

The only minor gripe? My shipment arrived with an opened box and loose batteries bouncing around. Not ideal, but all 12 worked perfectly so I can't complain too much.

Bottom line: If you need reliable, industrial-strength power that won't quit (and won't break the bank), these Energizers are your best bet. I'll definitely be buying again!
