## Questions & Answers

**Q: How does the warranty work?  whow will provide a new battery in the event of a failure?  the weize store doesn't seem to by weize? thanks.**
A: They provided a shipping label for the return when I had a problem. I messaged back and forth for a few days and after doing what they asked and giving them the information they asked for, they provided postage for shipping back to a USA location in Georgia. 
Some folks really need to pay attention and READ before you go on blast and leave bad feedback or answer questions here even when you DONT actually own this product. I have five of the 100AH LIon batteries and have only had one problem over the two years of ownership and the company took care of me once I did what they asked.

**Q: Can these be used with a wing generator?**
A: Yes but you will need a Battery Charge Controller (BCC) with the same voltage (input) compatible with th output of your wing generator and BCC output matched voltage of the battery or battery bank.  These are 12Vdc batteries for a single battery or multiple batteries in wired in parallel.  You might also add multiple batteries in ‘series,’ where 2 batteries would give you 24Vdc or 3 = 36Vdc and so on.  Some charge controllers also incorporate an inverter to provide 120Vac or you can use a separate inverter if you even need or want 120Vac in addition to the dc voltage.

**Q: Is there a customer service contact email or phone? I have not found any way to ask a question.**
A: use the contact seller option in the Amazon sales listing to initiate contact

**Q: What is the cell grade?**
A: I believe they are A.
