It seems that has changed the logitiel PANASONIC PANASONIC LUMIX DMC TZ7 since the month of June 2009. Result is the obstacle course to the user who has the most trouble finding a really compatible incompatible battery at a reasonable price. To believe that PANASONIC is doing everything to force us to use its own batteries at full price. Not friendly PANASONIC. There's something to be a little disappointed right?
