12Volt Car battery was too weak to watch videos on lap top?
I spend the weekends on my boat weather permitting so my LT is used for TV/video.
I use this connected to the boat or tow vehical 12V socket to power LT.
the current LT battery is charged at only 6%(even when plugged into 12v socket) I can watch only for a few minutes maybe upto half hour of recorded TV stored on flash drive then LT turns off message concider replacing battery.
?1. Why is 12Volt Car battery too weak to watch videos on lap top LT operates on 10.4v?
just received new battery it was charged to 69%
?2.Is it necessary to condition(run down to 0%) lithium ion lap top battery?
If yes how many times?
?3. should play videos w/ only LT battery wait till x% of drainage then plug into 12v socket?
I’ve never had much luck w/ batteries any tips for me is appercheated.
