Weight saving whores - Lightweight Batteries *discount content!*

[david25]

My fat battery is a 70 Ah type as well while I know A3 2.0 TFSIs just having 60 Ah.
Keep in mind ''Amp hours'' isn't the one and only. ''Cranking Amps'' is even more
important ro start an engine.

So if you don't listen to music while the engine isn't running I don't see any issue
reducing the Amp Hours radically.

This guy (USA) had a 60ah Varta from the factory (and only 480a)

Wrong link, David?

60 Ah is way more above minimum.
If you are careful 25 - 30 Ah should start every day.

[Tfsi_Mike]

15AH here    Am careful and starts every day

[the bruce]

No doubt, Mike. 

But I wanted to be careful as well. Careful to recommend.
A Braille offers much higher crank amps than conventional batteries
and I kept in mind technically non skilled people reading this. So
better have some reserve.

Helpful and accurate as ever 

I didnt leave the CTEK charger in the car when I dropped it at the dealers, I might drop it off tommorow after work as it will probably be sat in the body shop for a week of 2

Anyone suffer with flat batteries then?

[Tfsi_Mike]

Thought id find you here :p

After 4.5 - 5 days it didnt have enought juice to crank over.

Ive got an out door extension run outside the house with CTEK conditioner charger keeping it topped up.  If you dont use the car much could use it just for 1/4 miles and track days?

[Janner_Sy]

4-5 days isn't ideal tbh, plus my car is parked about 30m from the house sometimes for 4 days+ without use

Interesting idea for the spare battery though

[Blade]

Mine has been left for 3 weeks or more and started 1st time?

[Tfsi_Mike]

Might give it a test    was 5 days and didnt start but Dont think Id fully charge it prior due to being giddy and inpaitient lol

Found this:



As far as I know - All the CCA for the manufacturers is done at 0F, and the CA is at 32F, all this info is off the manufacturer website.
Acording to Autozone website the 240sx needs 360 CA.
So if you want 100% factory reliability even at 0F you want to be shoping around for something that will have at least 360CCA.
For those of you where the weather gets in the negative digits (F) you will want somethign that has a CCA > 360 at 0F
The battery I had in (Advance Auto Parts stock replacement stuff) weights 37lb..
READ THIS:
In BLUE are the brands whose CCA Ratings seems either off or make it hard to find their testing methods.
Deka Batteries are more than likely to be Deka ETX rebadged -- Their advirtised CCA IS PROBABLY NOT PERFOMED AT 0F.

Surely it wont be long before Lipo battery prices come down to a reasonable level and our batteries then weigh about 1.5Kg

You forgot to say ''.... and deliver 100 Ah + 1000 CCA''.
