Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month
Pros:
Very cheap compared to 'normal' batteries of the same capacity.
Cons:
As stated, not the full 4000mAh's, but pretty close. Also enough for my use.
OtherThoughts:
Very durable. I use them to power my ignition on a race bike and they hold out for more than a few sessions. They don't heat up while charging, nor while in use. They can withstand even a few shortcircuits, so: very durable.
Bottomline:
Not the capacity as advertised, but if you don't need exactly 4000mAh, why not buy them? After all they're a few times (!) cheaper then any other alternative!
Very nice for the price
