Let me start by saying these Tenergy C batteries are a STEAL for the price. I bought the 12-pack for my kid's toy collection and old household gadgets, and they've been surprisingly reliable.

The Good Stuff:

• Crazy value - 12 batteries cost less than name-brand 2-packs at local stores

• Worked perfectly in my vintage label maker that's been collecting dust (exactly like one reviewer mentioned!)

• No leaks so far after 3 months in various devices

• Surprisingly good shelf life - tested some after sitting for weeks and still showed full charge

The Not-So-Good:

• Had one dud in my pack (though with 12 batteries, one failure isn't deal-breaking)

• The plastic wrapping feels cheaper than premium brands - but hey, you're paying for the battery, not the packaging

Real Talk:

These aren't going to win any beauty contests, but they deliver exactly what you need - affordable power for basic electronics. I've used them in everything from Christmas decorations to Nerf guns (yes, they work great for those too!), and they perform just as well as my usual Duracells.

Pro Tip: Like another reviewer said, always buy batteries in bulk. These are perfect for stocking your junk drawer. Just don't expect them to last forever in high-drain devices - they're best suited for remotes, clocks, and other low-power gadgets.
