Many places sell batteries for cordless phones and have cross-reference
guides by model number, also by size, shape, voltage and type of
connector used.

The battery packages have a list of cordless phone model numbers they
are designed for. Wal-Mart carries a pretty extensive line of
cordless phone batteries at competitive prices, probably not much more
than the shipping costs charged by an eBay seller.. The ones I have
seen in Wal-Mart are GE/Sanyo brand. I have also seen cordless phone
batteries in many other places; Walgreen's for one, I believe.

Make sure the connector matches.
