Product Description:
2 Pack, 6 Volt, Lithium Battery Module, Works In The IF-275 & PUL-275.

Rating : - Six volts each!
Not only are these batteries six volts, but there are two of them! They come in an attractive black case with a convenient pointing arrow. These are by far the best 67A-67D 6-Volt Lithium batteries I have ever purchased.
