Having recently purchased an '07 12gsa the battery could do with being replaced shortly.

As a tight fisted scotsman, I want to get best value for money.

Any views, opinions or bigoted comments appreciated on which one lasts/works best.
 
Get a yellow one :thumb2

What are you basing that on? JJH
 
It has to be lithium specific

Can you charge these using an ordinary battery charger?

The instructions on charging this type of battery are quite specific. The first is never let the battery get completely flat as it will not recharge after that! The second is that they can be charged with a conventional battery charger with the following caveat the charger should at no time deliver a higher voltage than 15V nearly all battery chargers charge at 14.4 V . The reason this is mentioned is that some of the newer intelligent battery chargers can do a desulphating stage on a standard lead acid type battery. Different chargers use different methods for this. One way is with a higher initial charging current, which is no problem for the battery , the other way is with higher voltage... this will damage the battery. So you must know the way you charger works. One other thing is that the lithium battery does not like trickle charging so be aware of that. One very handy feature of the battery is it has a charge indicator simply press the button and it will let you know the state of charge. I have heard also that the batteries recharge much quicker than a standard lead/acid.

It is not important to most bike owners but the first thing that I noticed was how light this battery is compared to the standard BMW battery. Changing the exhaust can and fitting this battery has allowed me to fit a full set of adventure style engine protectors and still be lighter than standard !!!!!!!!!
 
By bigoted I mean the following.

If I buy something, it must be great, as I am great and would not have bought it otherwise.

A circular argument I know, I'm looking for objectivity not subjectivity.

As I am the shape of winnie the pooh, whilst any weight loss is always a good idea, better starting/longevity is probably of more importance to me.

Looks like more monies are heading motorworks way.

Thanks to everyone for their comments

Not at all true have you read the instructions The Lithium battery can be charged using a standard battery charger with the caveat it does not charge at greater than 15V nearly all chargers charge at 14.4V with maximum 14.7V

Of course you are paying the money BUT the Lithium battery does all of these things in bold better than a lead acid battery, that is not my opinion it s from actual motorcycle magazine testing of the batteries. Go online like I did and do a bit of real research on this type of battery and get real world reviews of the product... not I have one in my bike and it is the best... although I have never tried the alternative :)


interesting real world testing ... well I thought so anyway :)

Float chargers like the Optimate are VERY bad news for Lithium cells.

My bike gets regularly used so a lead acid is fine though extremely heavy and the space could be put to better use.

Brother has four bikes. He's always buying batteries or swapping them about. Lithium (LiFePo) would suit him a lot better as they are not harmed by lack of use and as long as they retain enough charge to start the bike should never need to be charged with a mains powered charger. Being so small they are also convenient to swap from bike to bike. He can only ride one bike at a time so one size could fit all.
 
Just to thank everyone.

Having checked the voltage output from my charger 14.7v and 3•6a; I've purchased a lithium battery.

Hopefully it isn't to cold this winter........

A normal charger is fine but they won't tolerate over voltage. Keep the optimate well away.

The lithium might need a few attempts when it's really cold. But you'll know that.
