I drivw a 1998 Accent 1.5. In the 7 years I have gone through 4 battery's. Les than 24 moths on a battery. I anyone else had battery's going so quick. I have had the electrical system check more than 4 times - no fault found. Altenator replaced also. I allways buy good quality battery's. Further I have no problems with the car

It sounds like you have a pretty poor Auto Electrician.

Maybe get an opinion from another Auto Elec.

I have been to more than 3 auto elecs. It just seems as though the car is for some reason hammering battery's. My wife's Mazda has been going 5 years with the same battery's since we baught the car new.

Will it be worth it to have the alarm/immob replaced, as one tech speculated that my alarm might be the culprit.

Hi there,

the average age of my batteries were 9 (!) years before replacing them.

My tip is simple: Before each winter put the battery to a specialist who will check acid concentration and full charge the battery. Of course the charging of your car/alternator needs to be checked/monitored in a scenario when most of electrical devices are on (eg. ventilator on position 4, AC, defroster, lights, audio) - even in this scenario the checker should display green, means alternator is still charging with 14.4V.

I understood from my specialists, in reality unless you go on very long trips the alternator does not full charge the battery (just about to 80% of capacity lets say). Thats why You need to fullcharge it once a time.

In case, Your alarm does not have its own battery- and as the alarm is mostly On just discharging your battery - it can be than your alternator does not have anough time to charge that back and your battery is than getting into wrong condition. If the battery is charged to a very low capacity for about the month - due to some electrical processes it can dead fully.

Recommendation: needs to be fully checked what happenes in your electrical system/take appropriate action like add dedicated battery to alarm/get higher capacity battery (I suggest 55Ah instead of 40Ah which is inside). You have to ensure that the capacity is in year average about at 70% and as mentioned once a year charge it to 100%

Kind wishes, Attila

My advice isthat it could be your stereo as old or at least two-three year old stereo's tend to draw excessive power whilst not in use.

Another point where to check is the boot light as the hatch lock in some Accents can fail leaving the boot closed but still supply negative power to the boot light , thus leaving it open.

If it's your boot light then to repair the boot has a rubber grip cap on the LHS and RHS unscrew these caps and remove, attach two washerson each screw to bottom side of rubber and re-secure. On to top part there are two grip teeth that will also require two washers at least on both screws, this should solve your boot rattle problem and boot closure problem.

Let JOHNC know if that isn't your problem as I can diagnose any electrical fault that may arise...... :)

you could always maybe check you wiring from the battery to to the alternator make sure it is not rusted and al the connectors are clean, could not be getting a full charge through due to bad wires etc. also make sure the grounding on you battery is still secure and not rusted where it attaches to the body.
