    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:

    Good capacity

    Almost no self discharge

    Protection circuit works as expected.

    Cons:

    No that I could think of.

    They are a bit longer than standard 18650s due to protection circuit. It might be a problem in some application when battery sockets are tight.

    OtherThoughts:

    I didn't measure the real capacity so can't say if it's real 2400mAh. But accus performance is good enough not to spend time playing with measurements ;)

    I have an "intelligent" charger now so maybe one day I'll check them

    Bottomline:

    I use them with SKUP00936 charger for over 2 years now and they work as they were new. It was just a great deal. They are great for my flashlight.
