According to the Power Sonic web site, the PS-1221 has a different  
form factor than the PS-1229.  The only one which matches the 1229  
case size (actually 1 mm wider) is the PS-1220, which is rated at 2.5  
Ah.

The PS-1229 is still listed, by the way.

A Google search located the Universal UB1222 battery, which has the  
same case size and is rated at 2.2 Ah.
