Good capacity, but a little on the long side
December 14, 2019
This high capacity battery gives me prolonged runtimes and the option of plugging it into a USB charger or putting it into an external charger. The battery has a red indicator light at the top that changes color when the battery is charged. The battery measures 70mm long and works fine in many of my flashlights that take this size battery. It may be too long for some devices though.

I am satisfied with the purchase.

So far so good.
December 24, 2018
Still testing but so far it works great. Have only charged twice so far. Only needing a cable and not
having to pack a charger with me will be great. I still carry 123's as back-up, at least until proven.
