Just got my hands on the Amazon Basics Rechargeable C Cell Batteries and I'm pretty impressed so far. The fact that they come pre-charged is a huge plus – I was able to pop them straight into my kid's toy without any waiting around.

The 5000mAh capacity seems legit – they've been powering our wireless keyboard for weeks now without needing a recharge. That's way better than the generic brand we were using before.

I love that they're rechargeable up to 1000 times. Did the math and realized this pack will probably outlast the device it's powering! The frustration-free packaging is nice too – no plastic clamshells to wrestle with.

Only minor gripe? The charger isn't included, which seems odd for a 'basics' product. Had to dig out my old charger from who-knows-where in the garage. But hey, at this price point, I can't really complain.

Would definitely recommend these for anyone tired of constantly buying disposable batteries. They're not fancy, but they get the job done reliably.
