## Questions & Answers

**Q: Need to speek to someone regarding my inogen g4 i would like information on battery.**
A: Column Pair shown in the photo is not one that comes as a standard replacement battery for a Inogen G4, at least not with my unit.  There are two batteries standard in the G4 that I have. They are the BA-400 (Li-lON) 14.5V,  3.5 Ampere Hour and the BA-408 (LiION) 14.5V, 6.5 Ampere Hour.

**Q: Will these go bad if you dont install for 6 mth.?**
A: The columns do only have a shelf life of about 6 months if they are not used.

**Q: Is this genuine inogen? Would prefer seller answer only. Thank you.**
A: Katherine, the manufacturer is shown as being Inogen. I have purchased this product and am well pleased. Especially like the price.

**Q: where is the reset button when replacing my pillars? How often do these need replacing?**
A: The machine will prompt you and direct you how to reset.  As far as how often I replace them, I hate to say so but every six months and I only use my unit maybe 15 hrs per month,  Inogen claims you only need to replace them every 1-2 years but I have not been so lucky.  Hope this helps.
