Original battery (for more security because I have been burned once in the past by a "Chinese copy" of poor quality on a different type of battery LUMIX FZ20!) Absolutely identical to the one delivered with the AFN LUMIX FZ150. Great price (although still expensive ...) in relation to other traders (Darty, FNAC, ...) that "push the plug 'a bit far - dare I say - and make a profit shameful product.
