p.s.
i like how they have the ""SIMILAR THREADS"" at the bottom of the page....
looks like it could come in very usefull ..
can it be done on this site ??
edit for question: why arent optimas on there ..??
i thought they were the best batteries around .......................?

My car is 2007 and the battery is OEM. It died once when I went over sea for summer vacation this year. I jump start and drive the car until the battery is recharged back to normal. Would it die any time soon in this winter? How can you tell if your battery is dying in a week or so?

I dont have any reason to believe its something other than the battery. I have an aftermarket audio system that i use everyday and still havent had any problems with anything. There is always a constant draw on the battery regardless as with any vehicle. The battery was 18 months old....some people are lucky to get 8 months out of theirs. As the guy at AZ said.....Nissan batteries just suck haha.
Also....my maunal mode shifts are much much faster and the radio sounds much better. I thought it was just my imagination...but yesterday after having the new battery in......i was able to put two and two together and realize that the slower shifts and lower audio was due to a weak battery, apparantely.

It may be useful for those with these vehicles to review the FSMs (pardon the formatting):
----------
Component part Description
Battery current sensor
Battery current sensor is installed to the battery cable at the negative
terminal, and it detects the charging/discharging current of
the battery and sends the voltage signal to ECM according to the
current value.
ECM
Battery current sensor detects the charging/discharging current of
the battery. ECM judges the battery condition based on this signal.
ECM judges whether to perform the power generation voltage
variable control according to the battery condition.
When performing the power generation voltage variable control,
ECM calculates the target power generation voltage according to
the battery condition and sends the calculated value as the power
generation command value to IPDM E/R.
IPDM E/R
IPDM E/R converts the received power generation command value
into the power generation command signal (PWM signal) and
sends it to the IC regulator.
Alternator (IC regulator)
IC regulator controls the power generation voltage by the target
power generation voltage based on the received power generation
command signal.
When there is no power generation command signal, the alternator
performs the normal power generation according to the characteristic
of the IC regulator.

Mine lasted over three years. Each time you run it down to dead zero, you lose about half the battery life. Each time you run it down, even as low as ten volts, the plates start to "calcify" and eventually, they won't conduct any more. So run it down three times.... you get the idea.

afaik mine is OEM...coming up on 7 years, so I guess I'm living on borrowed time! It's possible the previous owner had it replaced with an OEM unit, but I've had the car 2.5 years and the battery was not new when I bought it (unlike the tires and the front bumper paint )
u must drive your car like once a week. haha
typically from what i hear its like 3 years

Pfarmer,
Constant draw when the car isnt running....is placed on the battery. I know that the battery isnt the source or power while the car is running and only used when current draw is excessive of what the alternator can supply. Also, ive had grounding kits on every car ive owned, and have never had any problems that could be linked back to the grounding kit. Grounding kit has been on my car for almost a year now. If the grounding kit presented a problem im sure it would have made itself apparent a long time ago.
