Bigger Battery in a Sierra

I learned something useful.
I needed a new battery, as the posts had nearly rotted away.
I didn't want the same type this time, I wanted a more affordable, spill resistant, low maintainace type with real size posts.
I was tired of terminals busting, quite often.
Was also worried that a decent bump would have broken the post off.
In removing it, it did bust off.

Went to R and E in Croydon and bought the cheapest of the better quality batteries, which was listed as a commodore. $88 ruffly.

I was expecting all the hassles of fitting, like making brackets and stuff, but upon starting the job, I noticed Mr Suzuki had foretold this event, and there was a 2nd position for the bracket, which was exactly the right width for the new battery. Sometimes you win :)
All the batteries I measured in the shop were same height, so bonnet clearance was no issue. It was longer, too, but still fit within the original carrier. Just had to move some wires I'd put there for lights a few mm.

Now I have a MAN SIZE battery :)

PS terminal posts were on correct side for easier fitment, too.

600 :D mines bigger tha yours ;)

Salesman (an OL member) told me the cca was a good one, but I had no real idea, just wanted a man size terminal post, cos I'd replaced 5 or 6 terminals over a 2 year span, and smaller terminals were getting harder to find.

Mine is a 360cca Supercharge Gold MF (SGMF40b20DF) cost $90.
Been using it to power my winch, but I've boiled it, so I need a second I think. I think I'll just hook it up in Parallel + to +, and up grad the Alt.
Warn recomend 700cca min.
Ah so easy to throw money at. Just wish I had some. :cry:

I have just put in ... but not wired up yet a 760cca Supercharge MF95D31L battery. Cost $124.

Update: I have moved the supercharge to the Patrol, I have replaced it with an optima yellow - cause its spill proof :-) Its not hooked up for clarity of these pics.

As you can see I have put it on the passenger side after relocating the charcoal canister.
I also have a supercharge MF50 in the normal location its 600cca about $90... I think its for a commodore also.

I will be removing the drivers side one when the new one is wired in.
Hopefully it will help with leveling the car... Its 3 times as HEAVY as the normal one. UPDATE: I will be leaving this here.

These batteries seem great I had one in my old Toyota 4Runner for 7 years.

Is that just a generic battery tray?

Yeah is just a large 13"x 7" battery tray.
There is a 25mm RHS frame under the section of the tray that doesn't sit on the inner guard to support the battery weight. This frame is bolted to the firewall. The tray is bolted through the frame and to inner guard at the firewall edge of the tray and just to the inner guard on the jack edge of the tray where the guard supports the weight.

RC = Reserve capacity.
It basicly is a measure of how long the battery will last with accesories drawing off it.
Deep cycle batteries tend to have more RC and less CCA.
Starting batteries have high CCA for winding over engine but less RC.

Having said that Im not sure how it is measured or how the actual figure relates to the battery.

Optima yellow top fits in the standard battery tray! worth every penny been very sweet especially when the car has been sitting for ages without a run, it has never missed a beat

CCA doesnt mean much when your cranking over a 1.3 or 1.6. Because lets face it its not a big engine to turn over. Personally I would perfer something with a better continuous amp rating. So when your using a winch/spotties/fridges etc you will be able to use them longer.

For there size so far Lead Calcium batteries I have found have the best CCA, where AGM (Absorbed Glass Mat) batteries seem to have the best continuous amperage.

Just a thought esp for people who want/are running 2 battery setups.

Normal lead acid batteries increase cca by increasing surface area of plates, making them thinner and more of in the same package.... hence more fragile...

i found that marine batteries do wonders for mine, although i don't run a lot of accessories yet either, but they are designed to take a hiding physically.

I know Century have also developed a specific 4wd range that is heavier duty and plates are located more rigidly. I got a pair of their MP400's in mine, easy fit (spare in the same spot as BJJ) and reliable as.

i agree with Eff about putting a higher rc or ah over the high cold cranking amps battery.
