Grumps Posted March 30, 2020 Share Posted March 30, 2020 Greetings all. I am brand new to this site, although owned several Subaru’s over the last ten years. Due to this virus business, my 2018 WRX/STI is not moving much, & the Battery is getting low. My question is, “when charging, should I disconnect the Battery from the car, or just attach the charger while still connected to the car” cheers. Grumps.

Jay762 Posted April 2, 2020 Share Posted April 2, 2020 Hi I leave it attached as it stops the alarm going off. A decent charger with voltage level sensors should switch to trickle and not be constantly hammering the Battery and perm live circuits Quote Link to comment Share on other sites More sharing options...
