Changing battery.. recommendations??

[gmonkey]

hey guys/girls

Just wondering if anyone has upgraded to a larger battery in there jazz? Myn is very small one and when i put my stereo on it drains it so much the lights go dim everytime the sub goes... Anyone got any suggestions to over come this, not including turning off the stereo :P.

If anyone has put a bigger battery in was it hard at all, did you need to change your plugs/terminals??

Cheers for any suggestions/help

Not sure what would actually fit to be honest.... Probably an Optima of some sort.

Maybe you could get a tankier alternator? (or am i totally wrong:S)

What is the size of the stock battery? Measure it or write down the model number here and I can find out what equivalent models from other brands that you can use.

its 18cm wide, 12cm long by 21cm tall fairly small.. it has no model numbers or anything on it just a plain black battery :(.. a dud

doubt that'd work, due to i imagine a diff alternator would have different resistance in the pulley so therefor what driving the belt atm might not cope or over do it.. and the jazz don't really have much room under the hood as it is atm its cramped :p

^^ fair point

It should be an NS40 series battery. 197 x 129 x 224 mm

Edit: NS40ZL or MF40B20L

Relocate and get a bigger battery.

cheers aaronng..

yeh djt would but i dont really want a battery in the cabin and under the hood dont really have anywhere else to go.. i think i will just try batteryworld or something and cram a bigger one in its spot atm... just got to make sure it dont short on bonnet really and melt against the engine :P

Or get a battery of the same size but with higher CCA and RC ratings. That's what I did.

[gmonkey]

ahhh yeh good thinking wouldnt have even thought theyd do it for something that small...

Im using stinger spv35, good battery I recon for any audio setup.

What was your bad experience with Odyssey batteries?

[gmonkey]

cheers guys, going to look into this tommorow before work hopefully :)

What was your bad experience with Odyssey batteries?

Have a couple of mates with these, one was in a prelude and always dies on him. Would last them for like 2-3 days if not until they die. So they had to keep on recharging the cars before they go for a drive.

Now they don't use these anymore.

I think the voltage put out by the alternator could have been insufficient to recharge the odyssey. At least that is better than the exploding Optima in an Euro owner's engine bay!

Dunno abt that but was also in a mates S14, different alternator but still same problems

I am using Exide Extra, it seems pretty good and better than standard or factory.

If the lights dim in time to the music, you're getting voltage drop between the battery and the amp. The culprit may not be the battery but the wiring. If it is too thin, you get more voltage drop, because the amp draws a lot of current at 12 Volts.

Why not try one of those 1 Farad Capacitors in series with your amp (and right next to it)? They act as a "jar" for electricity that smooths out the pulsating voltage and gives the rest of the system time to catch up in between beats. Some of them have the "bling" factor as well.
