bigger car battery

[VectorX2]

how does affect to install a bigger car battery into a car? If batteries of bigger size but car engine starters of the same model would they be compatible?

You shouldn't have to worry about the starter. Bigger battery helps the starter get off better.

The only worry is whether the alternator is strong enough to recharge the bigger battery. Also depends on how big is big. If you're going from NS40 to NS70 or larger, then you might want to rethink the strategy. If NS40 to NS60, I don't think that'll be too big a load on the stock alternator. NS60 to NS70 lagi no problem.

from ns40 to ns60 no problem..
even ns60 to ns 70 got no issue...

BUT not sure from ns40 to ns70...
*last time hear guys with huge amp & woofer use 2 batteries?

 

[DanzEterna]

i just need a ns60 to start my car i dun have any sound systems in my car, just a single din cd player...
optional upgrade will be ns70.

i use two NS70 in my putra.... one at the front and another at the back..... alternator no kong also.

Why u use 2 battery bro?

 

[D7zul]

why need a bigger battery?

all i know, battery is use to start engine only.. and only to start engine..

after the engine starts.. all electrical components of the car is powered by alternator.. including charging the battery..

am i right?

Ok let me share some experience.. previously i encounter voltage drop problem, but now has been solved..
normally if our car is stock say NS60 and you upgrade to NS70.. that's just minimal upgrade or i should say not much different.. but if you are upgrading from NS60 to NS90.. den the problem you have is only the recharging back of the battery will be slow.. it's just like imagine you have a water tank in your house.. where the water tank is 100 litres and the incoming water supply is about say 30litre/min.. and your outgoing supply is constantly 50litre/min.. you might find the water tank i just barely enough to support as when it started to draw the water(current) you will be able to see the water incoming supply will keep turning on to support the water tank because of it's water loss.. so if you upgrade to a higher capacity this will be able to help more or less as most of the batteries/water tank will have a minimum water/voltage level to maintain till restart the charging...

so in this case if you change to a battery that is way too big, and your drainage is also high, your alternator will become vy stress.. it'll charge continuously.. as minimum charging will kick in @ 12.3V.. so whenever your car battery voltage goes lower than 12.3V your alternator will start charging again.. So conclusion is, you can change to big size but not too big like NS100 or so..

yeah, once car is running it's the alternator. But i think the battery has some play in the overall electronics too. Moving from a NS60 to 70 last time my ICE obviously was better but I also noticed a more stable headlamp light, rather than dimming everytime my aircon compressor kicked in.

Two NS70 batteries with 1 alternator to charge? I doubt that's the stock alternator! 70A alt to recharge two NS70's is quite interesting. Unless you've already changed to a 90A or 100A alternator la.

I also using 2 batteries one is NS90 Trane battery another is NS40 Bosch battery but i'm using 150Amp alternator to charge.. so charging is very fast..

so got any bigger alternator that fits campro a? i am having problem starting my car everytime...

i am using a 46B24RS/N60S battery currently, what size should i change to?

That's not the alternator problem la. That's your starter problem or battery weak problem.

Buy a good battery to begin with, not those cap ayam dunno what brand type of batteries. I personally like the Panasonic range of MF batteries. If after using a good battery your car is still hard to start, you might want to check the starter. Perhaps wire up a direct wire from the battery to the starter for starters, if still cannot then only change it.

 

[VectorX2]

the problem is, starter is new, the battery is new...

edit: i am using marathoner batteries

which terminal should i wire up directly?

 

[Izso]

Add a fuse as well, direct from battery to starter lor.

If starter and battery is new, then starting - which part is hard? Cranking or what?

 

[VectorX2]

weak cranking and need cranking for a long time only start, sometimes jerk at the starter

Check the grounding man. What people do is connect a direct live from the battery to the starter for direct current.

added another grounding cable from negative terminal to engine head, still no good

i tried to ask the accessory shop to add a thick fused wired from the positive terminal to the positive terminal of the starter but they refused to do it saying it needs relay and overload the starter. but in my logic isn't starter already wired in a way to get direct current from the battery but with a thinner wire as per advised by my foreman. please correct me if i am wrong.

Weak starter cranking often related to battery wear,cable connection/grounding and most often brush carbon of starter.
If the initial problem is due to battery,changing to new or bigger battery will help.how to check.go to electrician and check for cranking voltage(how low the voltage drop).if too low this might indicate battery problem,may need to recharge.
Bigger battery + normal alternator=full recharge slow,high load on alt.but battery life longer.
Normal battery + higher amp altenator=full recharge fast,alt last longer.but faster recharge leadto faster bat wear.

My personal experience change battery,change alt,extra grounding +relay to starter relay,still weak cranking.at last change new starter brush carbon.rm50 only.very strong cranking.

Sarutobi, the problem is he said he changed to a new starter.

VectorX2 - direct from battery to starter no la.. need fuse and/or relay one. Anyway, need to see your car to diagnose.

so means the cable to give direct current to the starter actually needs a relay and a fuse, i guess is something like battery --> fuse --> relay --> starter then use the existing power from the starter cable to trigger the relay?
