Put flat top AA (no quotes) into the search bar of your favorite auction site and you will see a bunch of lime green generic NiMH rechargeable ones up for sale. They cost about $US10-$US11 for a set of 4 with free shipping in USA. They still are a smidge tight IMO, but much better than normal ones.

Have you used them for any length of time? The manual specifically warns against using rechargeable batteries.
