Lithium battery

[MMN]

3 questions.

Is it worth it?

What do I look for, so I buy one that suits my K5 sv650s? V, capacity......etc?
From looking at web shops it looks like I need a 12v 4Ah.

Would this fit?

I know the size is not the same.

Need help ASAP

Unless you're stripping a bike to be as light as possible/track prep then not really

They're ****.

Thanks I bought a gel battery.

I know you already bought a gelled electrolyte battery, but AGM has advantages over gel, and still has no free electrolyte sloshing around inside.

AGM will give better starting power, generally have longer life and better low temperature performance, and they will recharge very quickly. As a extra benefit they are generally cheaper to buy. They are just as good with vibration as gel and do not leak.

Another point I'll add about Lithium batteries is that unless they specifically state they can be used with a standard Maintenance/Step/Trickle charger a new special charger has to be bought thus adding expense.

I'll stick with AGM :)


HTH :)

What's an AGM battery?

Absorbed glass mat, there is a fine glass fibre Matt between the plates (like a sponge) that traps the acid and gets rid of any spare acid, which means batteries won't leak even if case punctured. The plates are tightly pressed together and this holds the active material in place and makes the battery very resistant to vibration.

Thanks, every day is a school day! Inkilled my battery in the snow and was looking at replacement ones, thought there was only lead acid and lipo!

Yuasa AGM batteries are the way to go if you want a reliable tough battery that charges quickly and has good low temperature performance and good cranking amps. Also last a long time.

I've read a lot on this site over the years,

It's a great reference site.

Battery Technology has been behind-the-curve in Physics until recently and the basic principle was formed in 1799.So it's taken over 200 years for anything really new to come about but with the rush to,"Go Electric" battery technology is now moving fast.

Maker better batteries is harder than most people imagine, they seem to work well to start with but then as they go through more discharge and charge cycles unexpected problems show up. There has been hype around revolutionary new batteries many times but then everything goes quiet and they don't make it into production. Many people think super and ultra capacitors are the new answer, but they are just a helper for a battery as their energy density is terrible (10 times worse than lead acid) but they can accept and release energy quickly, so maybe good for regenerated power on vehicles, but not as a substitute for the battery.

Bear in mind that the energy storage of capacitors is made to look better in the graphs on website in link because graphs are on a logarithmic (base 10) scale.

Lead acid batteries work fine in general. Problem with bikes is they are miniaturised, sometimes to a stupid degree. They last for years in a car though. Bigger is better so bikes will always suffer most. The SV battery compartment is small and the stock battery is stupid small. Big battery big amps is needed to get the best out of them, especially for a high compression twin.

A lot of side car guys run a car battery located in the side car. No more battery problems.

There are some interesting projects going on as well :)

Still using Li-Ion batteries though......
