Hi.. sry to hijack ('borrow') this thread for a (few) questions..

 

1. what are the risks of shifting my battery to the rear compartment like the boot? will running the xtra cable behind increase the resistance or have a higher risk of shorting wif the body of the car? don't think running like positive on the right and ground on the left will make a difference...

 

2. do maintainence free batteries require ventillation?

 

3. i suppose i need special cables for this.. anyone knows any shops that does this thing and how much would it cost?

 

4. can this be easily D.I.Yed? don't think it's just a simple case of getting the cables, unplug and plug into the new battery in the rear..

sry i sux in electronics

 

doing this cos i'm thinking of making the front not look so cluttered, and also to balance things out by having a bigger battery in the rear as i don't have a spare tyre and i think the rear is too light... (front too heavy, which makes handling not so good)

No risk if you know how to do it properly. Yes it will create resistance but that you can notice.

 

2. do maintainence free batteries require ventillation?

 

Nope

 

3. i suppose i need special cables for this.. anyone knows any shops that does this thing and how much would it cost?

 

They are not special cables, juz get the correct AWG as for shops and prices ... guys out there please help

 

4. can this be easily D.I.Yed? don't think it's just a simple case of getting the cables, unplug and plug into the new battery in the rear..

 

Yes but you need to lay the lines in the shortest possible way, secure the battery. Before you do it... think where you wanna have it place... how to place... what you need!!

 

Hope that helps!!

You need not have to believe in me as I am no God. First I suggest yr mech start covering himself with more insurance in case of some knowledegable customers decided to legal action for damages cause to his car.Second suggest he start reading more books on car electrical/ electronic systems.If you believe you are correct in this practice , I suggest you try on on a top end european car and let us know of yr experiment.

Good luck

Try to buy gauge that are design for off-road vehicles, they are very robust and have built in cushion to prevent vibration from reaching the gauge needle.The price difference can high , in return you get accuarate reading and long usage life

okiz... thanxz

 

still quite skeptical about D.I.Ying.. cos they say the risk of starting a fire is there... later burn up my whole car

 

i hav a feelin i'm underestimating the car's electricity..

Are you out of your friggin' mind? For a procedure requiring me to fiddle with the fuel delivery system, the battery connections have to come off. How can you just start the car, keep it running to keep precious onboard memory and work with a highly pressurized fluid delivery system?

 

Either waste the memory or use memory saving devices.

[Yeobh]

Many european cars have thier battery site at the rear booth. Yes for the live cable you need to use a well insulated multi strain welding cable to reduce resistance.For ground just botl the cable to any part of the metal chasis or body will do.You will have to consider weight distribution when sitting the battery to the rear.

 

Ventilation is extremely important in our climate , even placing in the rear booth temp can easily reach to 40C when parking under the hot mid-day sun. Most of the maintenace free battery fails to live up to what the manufacturers claim due to high temp resulting in distill water vaporising and escaping via battery casing joints.

 

Use only highly skill auto electrician for such modifications.

 

Good luck

I have seen mechanics changing battery when the engine was running

 

usually the batery shops will use another smaller 12v battery to keep the circuit connected while changing the battery. i think this is a safer bet than keep running w/o the battery.

heat is a batt killer. one way is to fabricate a box and a CAI into it.

Ehh... This thread got me worried, as I am due for a battery change soon... So, what is the frequent technique used in Singapore? The 'on engine take out battery' method, 'use backup power' method, or the 'heck care disconnect battery' method? Should I ask them before I let them touch my battery? Would they laugh at me?

[Zeruel]

i think you can voice your concerns to the mechanics about it..

hmm, or you could change the battery on your own. but must take precautions la..

[Genie47]

How long have you got the car already? 2yrs? It has one more yr of life left. Trust me. Most MF batteries have 3yrs or more.

[Genie47]

Changing battery is easy. Just that with EFI cars now, you cannot afford to F*** up the sequence of terminal removal. With the older carburetted cars, anyhow gahsak remove also can.
