The Lumx G's are real energy guzzlers without spare battery in your pocket, I'm no longer out of the house. For more extensive photo tours can even be too little a replacement battery. So I do not see it a spending a lot of money for additional original batteries. Since not every battery it is fired under similar conditions difficult to draw a real comparison to the original. Chill for me there is no difference in the life. Use Lookit already for G3 and G6 have for not hesitated to order again Lookit.
