JESSPOW 4 Pack 3.7 V 21700 Rechargeable Batteries, Battery 5000mAh Flat Top Batteries for Flashlight...

Our Experience

I finally decided to try these JESSPOW batteries after my old ones kept dying out on me. I'd been putting off upgrading but when I saw these were flat top and could fit in my favorite flashlight, I took the plunge. They arrived quickly, looking sturdy and well-packaged. After two weeks of regular use, I'm really impressed with their capacity – they've lasted significantly longer than my previous batteries. I especially like that they don't get hot even after prolonged use, which gives me peace of mind. My only minor gripe is that the plastic coating on one of them seems to be wearing off a bit sooner than I'd expected, but it's not affecting its performance yet. Overall, these batteries are exactly what I was looking for – high capacity, reliable, and no frills.
