30Wh Battery For Acer Switch 10 E (SW3-013-1058)
[SM-Acer-AP15A3R-30Wh-2]

Was originally concerned about purchasing this battery after reading some of the other reviews regarding sizing and battery life. Battery arrived with a 74 percent charge on it so I used it like that until it ran down to a charge state. plugged it in to charge and it would only charge to 90 percent, used it like that seemed to work fine but before the next charge I rebooted the computer, it charged to 100 percent, I've used it for 2 sessions totalling one for 1hour and 32 mins left it in sleep mode for 2 days then used it this morning for another 38 mins. before needing charging. That's a total of 2 hours and 10 mins, that being said this machine is a 17 inch Dell and its always been a bit of a power pig. All and all I would say this battery currently is performing as well as the factory one did originally.
