Please note: Due to unprecedented demand followings Ralph Ferrand's article about this product in Classic Motorcycle Mechanics magazine, not only has the British arm of the German supplier run out of stock, but so has the Hanover warehouse. We have been told that we should expect new stock at the end of June or the first week of July depending on how arsey customs are.

Not heard of Sodium Ion batteries? You will do shortly - they are the latest battery technology with a very much greener pedigree than Lithium Ion as Lithium is expensive and has an environmentally damaging extraction process, not to mention the human exploitation of poor people often seen in it's sourcing. Sodium is abundant the world over and can be extracted from sea water and we're really not short of that!

Sodium Ion batteries are cheap to make and we have had a battery given to us to test - It has to be said we're impressed. Although there is only a small handful of these batteries coming into the UK currently from our supplier we have the one we're offering here on our 955i Speed Triple and it works a treat, although a fraction of the size of the specified battery it has half as much cold cranking power on tap and weighs a fifth of the weight. They have double terminals to make it easier to fit in your bike.

Unlike lead acid batteries these batteries don't discharge from an internal resistance and even if you do totally discharge them there is no damage, which occurs with lead acid batteries. They charge much faster.

The standard battery on our guinea pig Triumph is 12 amp/hour and this one is only 3, but it it provides 300 CCA (Cold Cranking Amps) against the stock batteries 200CCA. It seems that you don't actually need the larger capacity on a bike unless for some reason you want use your electrics for an extended time without the engine running - to be honest I can't imagine a time when one would?

This battery weighs less than a kilo and should last for five times more cycles than a lead acid battery. It will take fast charging and is leak proof.
