I need a new battery for my 2007 hawk sti, is there any sequence I need to adhere to or is it as simple as old battery off-new battery on?

 

Remove ....Neg- first.... then Pos+ when removing.

Connect ....Pos+ first..... then Neg- when refitting.

Avoids short circuits

apply lithium grease to termials, job done! This has been said to add 5/10 BHP

Hope your inside as its boody cold out there..

 

I'm built for winter buddy lol

thanks for the advice

 

Yuasa are good battery in my opinion

 

Some alarms like the ignition on, if they have battery back up.

 

which type of battery would I need? gonna see what sale euro car parts has on

 

is this one ok? its £55 with the discount

You have a Hawk Saloon?

I checked, and it seems that the battery dimensions are:

Width: 242mm
Depth: 175mm
Height: 175mm

Now, the best battery that will fit, is the Yuasa YBX9027, with 60Ah and 680CCA. This is at 190mm high so, unless your cables are already at maximum reach, it should be fine.


There's also a Hankook job, with 95Ah!...and 720CCA! Annoyingly though, the battery tray would need to be wide enough to accommodate its 304mm width. Plus it's prob too high at 220mm.

 

so the one I linked that euro car parts list is wrong then as its different dimensions to what you quoted

 

I noticed that. The thing is, those reg no wizards are notoriously inaccurate.

I entered model info on eBay and just went on the battery's listed.

So, ultimately, not 100% sure.


But looking at it logically, the depth is the same at 170/5mm. The width is only 12mm diff. So they'll be okay (unless your tray is right on the limits, widthwise).

The main diff. therefore is the height, your posted batt being 33mm higher (the YBX9027 is actually 190mm high). So if the one you posted IS correct, this means that the Yuasa is lower....so should be okay for the cables to still reach.

FTR, the battery I have on at the mo happens to be 15-20mm lower than it should be, and the RCM mechanic had no issue getting the cables on the posts.

 

Why not go and check the tray dimensions, your existing batt's dimensions, and also see, visually, if there'd be any leeway with the cables going lower.

 

just been to look at mine, its around 220mm long, 175mm wide and around 190mm high

 

Right.

So that means for that Yuasa to fit, the tray needs have at least 22mm - basically an inch - extra length (220 v 242). Could be the deal breaker....

 

The YUASA YBX9027 is "designed" for start/stop applications.
YBX5005 (65/550) is the silver high performance battery usually fitted.

 

or not......its a start stop battery according to this

Yeah, because of its high CCA. But that wouldn't be detrimental to anything else. It just means that it has more capacity to crank the car if left a few days and/or in cold weather. So win-win.

That's how I rationalise it anyway.

 

But yeah, there is indeed the 7000, 5000 and 3000 series which would be okay. I think at least one of them come in exactly the correct size too (albeit, with lower CCA ratings).

 

think I will try this one

^^^ 'Ironically', that happens to be the correct battery for my GC i.e. it's the 005L size (what the '...005' stands for).

 

We have had posts like this before, Ive always recommended the 005L as thats what I have on and it fits,
the 027 has been mentioned previously,
Ive had a price today for a S4 005l for £64 inc

 

The above is what's on mine, I paid around £64 when HellFrauds wanted £103

 

the above is what i bought yesterday to replace my existing Bosch s4 024 005L battery
