Batteries were shipped late, expected them before 20 days, came 28 days. New high quality 1.5V batteries usually measure 1.55-1.6V. So far, I tested and used 5 out of 100 and they measured 1.4 to 1.48V. This equals 5-10% loss of original new expected start voltage. I normally use this for low end watches. They last only as long as 6 months of continuous use. If These were silver oxide instead of alkaline batteries they would last more than 12 months of use, but the price may have been 3 to 5 times more. Overall rating: 65% satisfaction. Would I repeat this purchase? Only if I could not find better quality, price or speed of shipment elsewhere.
