My Polarcell 1500mA/h batteries from cellphone.de when combined into a double battery(supposed to be 3000mA/h) for Mugen back equipped N900 have already dropped down to 2128mA/h after only 30 days, I am pretty disappointed considering the price paid.
I wonder if they went with a new cheaper supplier after getting a good reputation, I wish we still had Scud batteries available, cheap and amazing capacity, lifetime over two years.
