Actual capacity measured rather disappointing 785 mAH, so we expect 800 + 10% = 880 in mint condition. By cons, they take time because I have four already in service for 13 months. However, I prefer Suppo found, delivered with phones, especially the Panasonic Eneloop Pro, measured 886 mAH and are more low discharge, so a more universal use, and less expensive, but I do not know yet what they give over time. Avoid by Varta Phone against that take maybe the distance but just not in the phones.
