Review: Exactly what I needed - I bought these batteries for my LED flashlight but held off reviewing them until I’d evaluated their performance. My flashlight gets plenty of use, multiple times per day. They’re a perfect fit, work well, last longer, and charging doesn’t take forever. The price was reasonable for two of them. Now I have a spare - always a good thing.
Review: Poor value - You should know that you only get 4. The description says 16 units. At $18.99 the price says $1.19 each. They know you’re getting ripped off.

Buy a charger that is sized to fit the battery. They are bigger than AA batteries. Fortunately they came charged.
