I have a Dell Latitude E6520. The Dell battery started experiencing reduced capacity, wouldn't run nearly as long on battery power, so I got a replacement battery (generic). The battery indicates that it charges up just fine, but when I run on battery power after just a few minutes - sometimes just a few seconds - it shuts down completely without warning.

I suspected the generic replacement battery was defective and got a different generic battery from another source, same result. Also had the first battery replaced by the vendor with another, same result.

I know generic batteries can be hit or miss, but three different batteries doing this? My original battery still works and does not shut down without warning, when it gets low I get the regular low battery alert.

Is there something other than crappy batteries that could be causing this, or do I need to suck it up and spring for a genuine Dell battery?
 
Solution
Finding quality aftermarket batteries can be tough. I normally don't like to recommend 3rd party suppliers but I've had very good luck with Anker batteries (AnkerDirect on amazon).
