The battery contains ordinary HR06 (AA)-sized cells so it's possible to revive the phone by replacing the cells. Modern cells would give you around 2000mAh so it would survive for quite some time.
How you do it:
- Remove battery from phone.
- Cut along the square area on the side facing the phone (hidden side), on the left, right and top side, skip the bottom side. The batteries are outlined in the square area, so cut out along the outer rim of the square area.
- Cut of the + and - connectors from the batteries to the pack. Make sure they are accessible through the hole you made when cutting the pack open.
- Remove the old batteries.
- Get a 4-cell pack of new NiMh batteries and arrange the cells in the same way as the original cells. Preferably the batteries with solder fans welded on, it's a lot easier to work with.
- Solder on some short wires to the battery pack terminals in the pack casing that remains from what you cut from old batteries.
- Insert the new batteries, pay attention to + and - side. Solder the wires you just added to the battery + and - poles before final insertion at the top end.
- Bend back the piece cut out and use a thermal glue gun to keep it in place at the top. You can of course glue the whole cut-out in case you want the pack to be completely sealed.

This phone was the best phone i've ever had! I'd 2 of them. 1 was stolen (imagine that) and the other one was chrushed by a 560 kg granite slab. It fell more then a 100 times on rock, sand, dust, water and it never failed me. Can't say that from today's phones.
