Hoping for some help! We have a IS220D, 2006. It appears that our battery won't hold it's charge. We have bought a new one hoping that would solve the issue but it hasn't. We can use the car today then go to do the school run tomorrow and it's dead! Jump start it then it's fine for a few days then it happens again! We have ruled out the battery and believe that there is not a problem with the charging. People that we have spoken to with more knowledge than me, are possibly suggesting that we have something draining the battery overnight. Is anyone aware of what our problem could be or aware of a common issue that puts a drain on the battery when not in use as it does not matter how much we use the car, it rarely starts after being idle for two days, sometimes less. I am very grateful of your help.
