340ma draw too much?

Jim79 · 2020-10-28 13:03:22

08 toyota verso 1.6 petrol. Car battery about 3 months old. The battery is not holding charge. I put the battery in series with the ammeter and it draws 340ma with everything off and the key out of the ignition. Do you think this is too much. Could it be parasitic draw?

Definitely on the high side, my (VWs) drew between a low of 45ma and a high of 95ma, when you say not holding charge do you mean it fails to start the car after a day or two. A 340ma draw is 8.3 AH/day so battery should still have plenty of starting power after say 3 to 4 days of car idle. Have you checked charging voltage at around 14.3V with car idling?.
