    You should be getting more than two or three weeks out of it but it sounds like you've let it discharge too far and it's damaged something. Every time it goes flat it causes slight damage that reduces its capacity, by which I mean that if you buy a brand new one and charge it up, the charger will cut out at 100% (fully charged). The more it's allowed to go flat, the sooner the charger will cut out, say at 80%, thinking it's fully charged because it can't shove any more in.

    You can make a (very) rough calculation to show how long it should hold charge, but it's really too vague to be of any practical use but...

    My RX has a 60Ah battery in it, which means that it can supply 60A for one hour, or 30A for two hours and so on.

    There will always be a quiescent current draw from the battery to keep certain things 'alive', such as the alarm, the clock, the radio presets and the seat memory, perhaps even more. This current draw is generally accepted to be 50mA or 0.05A.

    If we assume a brand new and fully charged battery, that means  60Ah divided by 0.05A = 1,200 hours to go from fully charged to fully  discharged, which is  50 days or 7.14 weeks.

    Remember though, that the battery will be unable to provide enough power to start the car long before it becomes fully discharged, so you'll never actually get that 7.14 weeks in reality.
