Batteries were initially powerful, but quickly lost this capacity, so that after a short time an improvement to the old battery was barely noticeable. Both lost their power. However, a more slightly than the other (production variations?) For charger is not much to say. It has the batteries are fully charged. Nice to have, especially if the capacity has been greatly reduced and you have more load.
EDIT: Immediately after submitting the review of customer service has been reported spontaneously in me and has offered a warranty exchange. But I like to forgive an additional star *** for the good service.
