These batteries appear new and measure about 3.2V without load They were cut from a bulk pack, and no expiration date noted. A piece of cellophane tape was applied to the cut packaging to hold the batteries in place during shipping. This tape left adhesive residue which I had to clean with isopropyl alcohol before using. One star removed due to the adhesive residue. I purchased a package of two. The photos show only one battery since the other was put into use. Read more

I ordered a 3 pack of Panasonic CR2477 batteries from Amazon that were sold by MYBATTERYSUPPLIER. These were for my SensorPush thermometers. These Panasonic batteries previously ordered from DigiKey have lasted up to 25 months. When initially installed in the thermometers, I was pleased to see the battery voltage was 3.2V on all 3 units. But, within a few days the voltage started dropping. On the 12th day, one thermometer had a low battery warning, 2.2V. The other 2 dropped out on the 14th and 15th day of use. While repackaged in small plastic baggies, these cells appear visually identical to known good Panasonic batteries. But, these clearly can't deliver their rated capacity of 950-1000mAH. With an expected shelf life of 6-10 years, these would have to be grossly beyond their expiration date to deliver such poor performance. Either the vendor is aware of the expiration status of these batteries or lack any sort of quality control for the products they sell. I might have excused a single bad battery, but all 3 failing so quickly indicates a defective product. Wasted my money on this purchase. Should have paid more attention to the critical reviews. Wouldn't recommend MYBATTERYSUPPLIER for this model battery. Read more
