Good value - still working
Great battery, had it for a few months now and it still works well. Was easy to install and at a great price. Will buy again.

No complaints
It went in easy and it's lasted a month so far. A little pricey in my opinion but still a good buy. I also feel like the brightness in my flashlight went up as well once the battery was put in.

6v battery
I purchased this battery for a unicorn horse I picked up at goodwill . It fit perfectly into the compartment of the horse. Charged quickly and holds that charge for a while. I recommend this battery !

Nice replacement battery for Ion speaker
The 9 year old battery in my Ion Road Rocker Bluetooth speaker finally gave out and thanks to some youtube searches found this replacement. Hopefully it'll last just as long.
