**Q: Can you wire these in series?**

**Q: Is this battery a suitable replacement for an elnicell 382527 250mah 3.7v?**
A: The size is the only question  I would have.  I should work if dimensions are same.  Some manufactures  make batteries a little different in size for the same current capacity.

**Q: is the current dc or ac**
A: No such thing as an AC battery , batteries are DC
Perhaps you should have someone else work on this project for your safety
