i was filling up air on all 4 tires this weekend, and noticed that i couldn't start the car anymore. i immediately deduced that the battery got discharged since i was running the compressor for a long time( mga <=20psi kasi ung apat na gulong), at di nakastart/idle ung car ko.

i pulled out the battery and put it parallel with my uncle's ride -- but i attached the negative end onto the other car's body i was able to start up the other car and get my battery charged, pero i noticed na medyo nagstall ung other car when i tried to start it.

inisip ko na hindi nakastart ung kotse ng uncle ko when the batteries were placed in parallel, so nadiskarga din sya(thankfully not completely)

ung tamang sequence ba dapat is to start the other car, *then* place the batteries in series, para siguradong walang madidiskarga?
