Best Battery

Brendan S4 · 11-04-2018, 06:00 PM

Hi all,

looking for recommendations about which battery to buy for my S4.
Bike isn't used that often and kept on an optimate,
would prefer something with a bit more cranking power if possible.
Any help appreciated, cheers.

Hi Brendan, I have a motobatt from sportsbikeshop, good cranking power & decent price, used yuasa before but have been told they're useless since they changed to gel batterys.
Hope this helps.
Happy monstering - Mark😁

Thanks Mark, was looking at those ones earlier

+1 for the motobatt, has been a good battery, but looked after. Check amazon 'cos sometimes they are cheaper esp if you have Prime you can save on postage too!

I'm just over in Hamilton mate and I have a halfords trade card so get them at a decent price. Let me know the model and I'll check it for you

Thanks everyone for the info, was thinking about the motobatt and this has confirmed it.

cheers for the offer of the trade card, I have one myself but appreciate your help and

offer,

cheers,

Brendan.

While you're at it change the lead between the starter and the solenoid. Halfords do a heavy duty cable that fits, makes a big difference when starting.

Yuasa GEL batteries have much more cranking amps (CCA) than the old wet batteries ever had. They are standard on most new bikes these days.
I run a Lithium on one of my bikes, but other than that it is all Yuasa for me.

Can you remember which Halfords lead is the right size? Thinking of doing mine. Ta

Thanks for all the advice. Will definitely look at changing the lead between starter and solenoid. Read on other forums that you can buy a replacement kit for these leads as well .

Exactfit and some others? They are very expensive for what they are.

Brendan S4 · 12-04-2018, 02:21 PM

Was thinking that. Will measure the existing ones over the weekend and see about changing all the leads, every bit helps😀

Hi Darren - they do a selection of different lengths, can't remember what size it was exactly, the replacement was within a couple of cm of original though. I went for the red, in hindsight black would look more OEM though. I also changed the earth lead while I was at it, that was a bit of a faff as I had to remove the tank to get properly at it.

Anyone using a Shorai?

SteveP · 12-04-2018, 07:06 PM

I would recommend the Motobatt. My s2r has stood unused in the garage since October and started straight away on Sunday, a pleasant surprise, I expecting it to be dead.
