    Hey guys,

    I just bought a new replacement battery for my toshiba u300 off and ebay and was experiencing some really odd things. It's 4400mAH and after following the recommended calibaration techniques recommended, I get huge increases in battery wear. First charge, it was at 0%. Second full charge, 15%, third/fourth charges, stays at 18%.

    I am getting these measurements from mobilemeter and is seriously worried if I am doing the calibration steps wrong in a new battery and is afraid I might have messed up the new battery all together. In comparison to my original battery, the old one only shows 4% wear.

    Oddly tho, it takes a lot longer for battery to finish the last 10% when charging than my original one.

    Do you guys think this is a severe issue or would the measurements not be accurate? Did I do something wrong during the calibration or something? Please help!

    Did you buy a real Toshiba battery or some generic piece of crap? If it is the latter, then most likely the battery came defective.

    Is this a Lithium Ion Battery?, If it is, your draining the battery completely is damaging the battery.

    Calibration techniques that involve draining the battery completely benefit NiCad & NiMH batteries, not Lithium Ion.

    You cannot completely drain Li-Ion, circuit prevents (can be done but not at issue here). OP says following recommended calibration method don't think at issue. Running battery down is recommended (circuit prevents "deep discharge") at times.

    I don't have the answer tell us more about battery as asked.

    is it cuz the battery is physically decomposing or is it the faulting ACPI inside it? it's kinda hard to send back since it took like 1 month to ship here and i am somewhat reluctant to ship it back again...

    any way to fix it?

    Not really a way to fix it. Just next time buy a real oem battery, i cant stress that enough. Aside from not preforming great, they sometimes even pose fire hazards as well.
