Battery tender recommendations?

[Paul Workman]

We have two new batteries in our Vettes and I'd rather not chase around with a battery charger every couple weeks to keep them from suphiding. I'd rather just put them on a 'tender' and not worry about them.

That said, not all tenders are created equal. Some are "dumb" and can over-charge/boil out the battery. What I want is one with monitoring capability and will charge as needed and shut down (or "float") as needed the rest of the time.

Any suggestions as to what and where to buy?

TIA,

P.
