Exceeded expectations, almost perfect (Thinkpad T500)

While letting I came across products that promised less good experiences, so my expectations were not too high: it should work and be about 4 hours of battery life possible.

* Product ordered T500 (Type: 2243 7SG) for a ThinkPad
* There is a large capacity battery. He is like the original accessories therefore back on the laptop before.
* Manufacturer (LT sensor.): Sanyo
* Sensors and system recognize the battery without any problems
* No "adjustments" required to insert the battery into the holder (is the case of other replacement battery it lt. Rezenssionen the case. Here, the battery can be inserted as usual).

Experiences in using:
+ Good fit / no adjustment notwenig
+ Allows use between 4-10 hours (full load, brighter screen, Wi-Fi / Word Processing, dark screen, WLAN off). Even 6 hours Wi-Fi were enabled previously no problem
+ No (sudden) power waste; even after temperature fluctuations (winter outdoor temperature at 0 ° C in rooms with 20 ° C).
+ After 10 charge cycles no excessive capacity waste (see below)
+ Loads very fast (felt - not measured - fully charged in about 2 hours 80%!)

- Install works fine. Also, the safety lock fits perfectly. However, the removal is more complicated: The battery is slightly larger than the original part and verkanntet thus very easy. Only with a lot of feeling one can hold in one hand the lock tab and pull with the other battery. Otherwise, it is recommended that a second person to ask for help shortly. Taking the battery with both hands straight out, he did not verkanntet.

! Customers report a problem of sudden Komplettausetzern (laptop is easy suddenly). Was able to observe, is in which the laptop gone out without warning a similar problem. The laptop dannach read however without problems and power switch on and use them again. I can therefore not certain the problem traced back to the battery - but not rule.

o Max. capacity was in the beginning (of course) is not reached, that is only about 71.000mWh after calibration by the Lenovo Energy managers were of the nominal capacity of 71.280mWh accessible. After 10 charge cycles is the max. Rated power on 70.880mWh dropped. For me, this drop is normal, this could watch the same even when original battery.

All in all:
Very satisfied, very good value for money, no serious shortcomings (assuming that the laptop failure was not caused by the battery pack).
