Can you wire these in series?

You can wire in series or parallel depending on what you are looking for in voltage and current capacity.

Is this battery a suitable replacement for an elnicell 382527 250mah 3.7v?

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.

is the current dc or ac

No such thing as an AC battery , batteries are DC Perhaps you should have someone else work on this project for your safety
