Problem:The battery fit perfectly into the Thinkpad X200 that I have. It doesn't add much weight to the laptop and I am happy with the purchase. I get about 3-6 hrs on it, depending on what I am doing; The old battery would have been 7-9hrs (Lenovo brand). This battery is alot cheaper, and thus you get lower quality battery components to make the battery life lower. Lenovo's power manager identifies the battery as:<br /><br />Full charge capacity: 43.09Wh<br />Current: 1.10A<br />Voltage: 11.77V<br />Wattage: 12.56W<br />Temp: 20C. (just booted up).<br />Cycle count : 4<br />Manufacture name: SONY<br />Manufacture date: 2013-08-29<br />First used: 2013 - 08<br />Device chemistry: Li-Ion<br />Design capacity: 47.52 Wh (sticker on battery and specs on amazon show 49Wh; so it is a bit low)<br />Design voltage: 10.80V.<br />Also, the serial number that Lenovo sees is the the same as the one that is stuck onto the battery.<br /><br />As you can see, the design capacity has already dropped 4 Wh with just 4 cycle counts (thus 3 star not 4). I'll see how this continues and if the full charge capacity keeps dropping, if it seems to level off where it is then I'll bring it back up to 4 stars.<br /><br />I purchased this battery on Nov 11, 2013; so it was manufactured just months before, which is good. Sometimes I see things that are years old being send out via amazon...<br /><br />As per the directions send from Ankey, I plugged the battery in, dropped it to 7%, charged to full overnight, dropped to 7%, and repeated for 3 cycles to fully exercise the battery. Hopefully this will help keep the full charge capacity where it should be.<br /><br />Overall, I think it is a good investment since the battery cost $36, compared to the Lenovo's $188 price, however, at the time of writing this review, the Lenovo battery is on sale down to $70... for that price, I might have grabbed the Lenovo brand instead to ensure that I got the higher hours.<br /><br />If you are planning to use this for flights, then you might need to carry a spare, since the 3-6hrs is not a lot of time. From what little I've seen so far, recharge time is about 4 hours, when the laptop is running. I am not sure when it is not running.<br /><br />The quality of the battery itself is good. It is completely sealed; and the blue backing, (which I thought might just be an insert) is actually glued down onto the battery.<br /><br />Shipping\packaging wise, the battery comes in the box shown which is made out of very sturdy cardboard and the battery itself is surrounded by foam to prevent damage.<br /><br />I would buy again if I needed to, of course based on how long it lasts with this 1Wh per cycle count trend I am hoping to see stop.
Solution:
Decent cheap battery, unsure on how quickly I'll have to replace.
