BMW 740i model 1999 - Battery life is less

Battery dies within an year. Some times the hazzard/warning lamps lights up and continues for some time and then stops. I wonder if this is the reason for the short-life of the battery.

Battery on BMW 740i keeps dieing


you need to disconnect one side of the battery, put one lead from an ampmeter on the battery post you have disconnected and the other ampmeter lead on the cable you took off the battery. with nothing turned on on the car , all doors closed the reading on the ampmeter should be no higher than 0.17 amp, if it reads a lot hgher go to the fusebox and remove one by one all the permanent supply fuses looking at the reading every time until you find the circuit that is causing the high reading, this will be the drain. alot of the time it can be central locking system playing up, boot light, glove box light not switching off, stereo wired wrong. hope this helps.

30 Seconds High Beeps with Hazzars


The battery is low which is causing the alarm to activate, replace the battery. I'm going to guess that it gets pretty hot where you are between the times you listed. BMW cars have been known to be affected by heat.

Battery or radiator light on a 1999 BMW 318i SE


The below is taken from another site written a year ago:
What you are looking at is the Service Indicator. The green, yellow and red lights let you know when service needs to be performed. The green lights mean everything is still good. The yellow lights mean "anytime you're ready." The red lights mean do the service ASAP. There are also two other lighted areas. One says "inspection," the other says "oil change" (or oil service.) An oil change is an oil change. However, there are two inspections: Inspection 1 is normally at every other 15,000 miles; Inspections 2 is at every 30,000 miles. Your local BMW dealer should have a pamphlet listing all duties performed for each of the services. Inspection 2 can run you around $400-$800 depending on the service station/dealership's labor rates. Inspections 1 should be around 1/2 of that. You should have your oil changed about every 5000 miles. Dealership oil changes can range from $35-$65. A BMW that is well taken care of will last a long time. 

FYI, don't be surprised if the SI (service indicator) board decides to **** out one day. I'm surprised to see yours is still working (they usually die within 10 years unless someone went thru the expense to have it replaced.) If/when it does go, just gauge your services by the mileage intervals I've listed above. I'd also recommend when you stop into (or just call) the dealership, go to the parts department and order an owner's manual for your BMW. Should be less than $20 and get to you in about a week unless they have one in stock.
When the service tech has performed the necessary service(s), he will reset your SI board so that only green lights are showing.
