I have to replace the battery in my 2008 Maxima every year. The last one lasted 6 mths. Any idea what could be draining it.

1. If you parked it 6 months ago there is a chance you;have chewed on wiring if it's outside by a field.
2. make sure fuses are good, i know but (check anyway)
3. does it have sufficient fuel to start ???
4. if you parked the car with very low fuel left in tank , you may have a corroded fuel pump (internal tank pump)"trust me when i tell you this can happen"
5. make sure no one played any tricks on ya under the hood !!!, good luck

it is possible that the battery is faulty, most batteries only have two years warranty, it might be a good idea to replace it anyway because it may not last much longer anyway......hope this helps......cheers

Never.. just run it! Timing belts need to be changed, timing chains pretty much last the life of the truck. 147,000 on mine and no plans of changing it. Dealer told me that he has changed 6 in the last 6 years, many were not due to wear.

are you installing nissan starter not aftermarket one??

it should last about 5-7 years but if you have any other amps,radios,subs,or any electronics added to it-that may be causing the problem.

Hey! I have a 97 Maxima SE and it runs great too! I have been through 4 alternators in 12 years....3 in the first 5 and finally one for the last 7. Make sure you have a new- Nissan part specific alternator. And, make sure your battery is not weak nor small for your car size. Hope this helps!

battery going bad

A short somewhere. All shorts can lead to fires, so take it to the dealer or go to a mechanic who does electrical work such as a starter shop.

your alternator may be over charging.
