The battery is low and fits perfectly on my headset model (K 216 AFC) and at the base. The durability of the last battery was about 3 months, then oh reaches a full charge only for less than two hours. However, it is not worth to buy this battery here, because the same shop also again by more than half offering the absolutely identical battery also cheaper at amazon. All in all, the effective battery in my opinion for the price ok. Anyone wanting to use its battery last longer, but should not buy here.
