hey guys, so the past 2 weeks, when i park my car for more than 2 hours i always find my battery dead and not able to start the car.. what could be doing this??

is the battery gone, or are some electronics discharging the battery?

i also disconnected my amplifier just incase but it still does it

any help would be nice

 

Most likely it is a dead battery.

How old is the battery?

 

How old is your battery? If it's more than 4 years, it's probably shot.

To be sure, disconnect the ground lead and put a battery charger on it for a few hours, then check each cell with a specific gravity tool. If one or more cells do not come up into the green range, replace the battery.

-1.3L

 

Have the battery charged and load tested; have the charging system checked too.

 

ye its the stock battery from the 2004 model, so might be gone, it has that blue corrosion stuff on the positive battery lead that i keep cleaning off every few months.. i dont have a charger butill bring it to the shop they test it for free, thanks for replys

 

No forget that!

It is dead, your lucky it lasted 4 years and 9 months.

 

UUMMMM yes it is the Battery

 

Wow... that battery is definitely dead

 

Get a red top Optima battery my car cranks up every time even when it stalls most of the time since I need a engine swap....now only if I can convince the Mazda dealership that my performance upgrades did not cause my engine to fail!

 

Most likely just a dying battery; they don't last forever. But also make sure there isn't some drain, such as the trunk not fully latched (trunk light on).

 

Very unlikely that it's an electrical drain. You can park your car for two hours with the headlights on and a good battery will still have more than enough left to start.

Question?
When ur battery dies after 2 hours how do u start the car?
ie do u re charge the battery?
My vote is the battery is too old.
Mine died and I have a 06.

Forget about that optima go to wally world and get the maxx 24fs for 75 bucks
Fits right in the battery box even tho its about one inch longer, width is the same

but if u want to be sure
have the charging system checked
then the battery checked
then tell us what u did and the results
good luck

ken it might be a drain..cause its too old to take the drain for 2 hours. Ya a good battery would take it but not an old one.
I wonder how he keeps starting up the car if the battery goes dead?
If he recharges it, means it takes the charge.
But how long does it hold it?
Only a test will tell.

 

he prob push starts it

 

/\ dedication

 

haha its hillarious sometimes i have to ask someone to help me push the car down a hill to start it but yes thats what i do.. well this week ive been riding my ducati instead.. getting too cold for that tho...

ill get it tested since im getting tires installed, hope it is the battery. and any specific battery for an rx8? i looked around at autozone and specific battery for this car runs 90 bucks...

 

I had mine replaced after like 8 months of ownership when I brought the car after a flooding incident. Late 2005? Then November of 2007 battery died and I paid full price for a new one at Mazda. Last Saturday, I woke up to a dead battery again. Replaced under battery warranty. (So that one only lasted a year).

That means I'm on battery numero 4 in my Rx 8.

Just FYI

dont even bother testing it. Its toasted.

If you wanna save some money, get the Duralast Gold at Autozone, its about 80-90 and u get 3 yr free replacement and 84 months prorate after that. (assume Autozone still in business in the next 3-10 years )

90 bux is NOT expensive for a "good" battery with 3yrs or longer warranty.

You can go cheap and get Valuecraft, its 1 yr free replacement and its like 50-60 bux. You think about it.

For the record, Rx-8 use a Group 35 Battery. and when u see blue stuff on ur positive terminal, your battery's days are numbered.

 

poo 4000

 

He needs to put some AA batteries and maybe a 9 volt battery :D save money and get a energizer AA it cranks up my car like nothing! nah im just messin with you haha

 

Be careful about that. There needs to be air space around the battery. There's a service bulletin that gives the details.

Ack! I just tried looking up that bulletin at finishlineperformance, and the bulletin section seems to be gone.

Anyway, don't put in a physically bigger battery, and make sure that the clearance that was around the original is preserved.

Battery's dead, don't bother

 

^^I agree, don't even bother recharging the battery. Just go out and get a heavy duty battery like Duralast. You'll be better off and save time.

 

How long does a battery usually last anyways on the 8?

 

Not if it's an old, weak, battery.

^ My '05 is actually on its 'original' Interstate battery (it came with the upgraded starter and battery when purchased in March '06). I'll most likely get a new one next year tho'.

edit: battery TSB enclosed.

 

+1 its done.
