Default Honda grace hybrid (2015) 12V battery dead?

I havent been driving frequently because of covid...back in june my car wouldn't start...I showed it to the mechanic and told told me that since you havent driven the car for 2 weeks the auxillary battery (front 12v battery) is dead and it needs to be replaced...so I replaced the battery...now since I contracted covid 2 weeks back and had to be home quarantined...I again didn't drive my car for 5 days and the 12v battery is dead again...I jump started the car it worked fine but right after 2 days of rest the battery is dead again and the car won't start... There is an indicator in the battery suggests replacement since it's red but there is no battery signal in the dash.... What could be the reason? Can anyone help? Since we don't have much expert hybrid mechanics over here....


Regards

Not sure if it's the same but I had a similar issue with my G2 when I was bike commuting to work. Turning off the proximity key sensing gave me way longer before battery death. Then I also realized my 12v was wearing down as well..
