Hi, selling this battery which has just now undergo a full recell, where all the original crap quality Sunpower 2000mAh cells have been replaced for recently manufactured, genuine high end model Samsung 30Q cells with 3000mAh capacity and high discharge ability. The whole job was done to a high standard. Expensive spot welder was used, thick 0.3mm nickel strips so they will certainly not melt or get too hot. These new cells are on a different level and have a 10 years of shelf life. Grab yourself a bargain and get a battery with an extra 50% capacity compared to this same stock battery.! Any questions, just ask.
