It arrived in 16 days. All five are good in the range of 3.75-3.95V. Unlike the product information, it is a GNB brand as shown in the picture, but the specifications are as described and there is no problem. It was rather good. The tracking information is unreliable, but it was delivered quickly. Thank you!
It seems that there is no 300mah. When I try to use it, it is about 240mah and does not reach 250mah. There is nothing that can't be used, but the operating time is less than expected.
Good little batteries. Unfortunately a bit small for what I was looking for. Quick delivery. Impressed.
