AA-PBSN4AF Battery for Samsung NP930SBE NP930SBE-K01CN NP930SBE-K02HK NP930SBE-K03CN NT930SBE NT930SBE-K28A NT930SBE-K38 NT930SBE-KT3W NP730QCJ NP730QCJ-K01US NP730QDA NP730QDA-KA1US 54Wh

I bought this to replace the original battery in a Samsung Galaxy Flex 2 alpha (14") laptop that was 3 1/2 years old. I received it and put it in the computer yesterday. It has been through one cycle of use/recharge.So far I like the battery. It was an exact fit for the original battery and came charged at about 70%. That lasted me about 6 hours of pretty decent use. I let it wind down to the 3% noted in the manual and then charged it to 100%. That took right around two hours, and I was using the computer the entire time it charged. At full charge, the battery life meter tells me I have about 10 hours of standby/playback life, but I have the thing doing all sorts of thinking, so it keeps changing my time.Battery came with 30 days return and 12 months warranty. I bought it with a credit card that gives me another 12 months extended warranty, so this battery should get me at least two years additional life even if I have to replace it under either warranty.I'll try to update the review after 6 mos and 1 year use.

It works. Make sure your battery is the same model number because the tabs are different in some models.
