Hi,

For the past 6 months, my car battery died about 5 times and needed a
boost to recharge.

What electronic upgrades do i have in my car: i have amps, subs and
upgrade speakers. The alternator is stock, and the battery is an
interstate one - all items replaced about 3.5 yrs ago. No capacitors.

Symptons:
a. On few occassions, it died because i left the lights on.
b. On most of the occassions, it died while i was idling in traffic
because of traffic jam, or died while in the drive through lane at Tim
Hortons or McDonalds, and playing my stereo.
c. At night, i see my headlight dim a bit if the bass hits too deep -
had to replace the fuse once since installation in 2000.
d. Once or twice, I lost sound from subs while cruising the highway,
and got carried away with the music. But when i stopped, and started
the car, the subs came back.
e. the power interruption only seems to affect starting the car ... i
can still use the lights and horn for a while, but they also finally
give up shortly after the car dies. but then once it is charged, it
starts instantly. I replaced the starter last year at Pep Boys, and
the problem still continued after that.

So, i am thinking of a solution to these problems. My car is really
old - a 1991 GXE with about 380k kilometres, so i might not be keeping
it longer - 2yr max.

So i'm thinking of replacing the battery as a start. what do you
suggest?

thanks in advance - Noela
