BARELY USED

WORKS PERFECT

HOLD CHARGE PERFECT

The batteries have seen very little use. I acquired them from a relative whose father unfortunately passed away; however, the device itself was in excellent condition and had only accumulated about 100 hours of use. Consequently, given their expected lifespan, these batteries still have plenty of life left in them.

I will update the post to show the number of hours on the concentrator unit. I also have more than 8 batteries available; if you are interested in making a deal for all of them, let me know.
