  • Too soon to tell
Size: 1 Count (Pack of 4) Color: 16340 Battery
The batteries arrived quickly and as expected. No problem at all. However it is to soon to comment on the quality of the product.

  • Fits Welch allyn
It had to be charged prior to usage. Fits easily into a Welch Allyn handle. So far the life of the battery is good.
