999 Replacement Battery.

Standard fitment Yuasa is where i would be heading - Halford's with discount if you have the trade card

 

^^^that^^^

just make sure when you add the fluids and tap the top down it's in properly or it can leak on it's side.

 

..which will mean you'll need a lithium battery charger also..

 

Buy a Shorai, best battery on the market by far

You can use a non-lithium if it’s of the correct voltage

 

Shorai LiFePo all the way

 

@Old rider maybe bought one recently

 

However you don't charge them up with a circuit designed for a specific sized Lead Acid battery.
That circuit may be placed very close to a hot exhaust and be working close to design limits.
It is actual going to take someone loosing a bike before my advice is heeded.....
There are already members on here you have suffered damaged to their motorcycles due to the installation of Lithium batteries on motorcycles not designed to take them.

Ask the battery people.
"I'm concerned that my regulator circuit on my motorcycle may overheat due to the fitment of your Lithium Battery.
My motorcycle will cost £+15,000 to replace, can you offer me a written assurance that you will cover this?"

PS
I've not association with any battery manufacturers, just want to pass on my experience of what can go wrong.

 

I would still go Yuasa standard fitment - similar price from Argos with the discount better warranty as well...

 

Here’s the thing. It will work and you should be lucky. But if you get a charging circuit fault you might not be lucky and it won’t be funny if it goes wrong. Is it possible to buy a lithium battery with additional protective electronics as part of the design so it can be guaranteed as OK to fit on lead acid charging circuitry even if that produces over voltage or current?

 

Not that I’m aware of but the Shorai batteries are Li-Fe not Li-po, or Li-Ion. So less to worry about as they will not burst into flames in the same spectacular ways as others on the market.

As with everything, it’s a personal choice and depends on what’s your most important buying motive. There is however too much scaremongering in relation to these batteries rather than offering a balanced view IMO

 

I’ve seen a picture of a Paul Smart burnt to a crisp by a Shori...

 

I didn’t say it couldn’t happen. I’ve seen the mess first hand that a led acid battery makes when it goes wrong too.

The fact is neither are 100% guaranteed

 

You been near Gatwick lately hmm?

 

100% it was down to the Shorai, or the fact the reg/rectifier hadn’t been upgraded to a mosfet type?

 

How the Feck is my view "scare mongering", dippy?
Where is my in balance you dinosaur?
