Looks right to me - for a 2009 model, as it has the later battery but no front disk. My first reaction would be that if it's been sitting at the back of a warehouse since 2009 then a new battery would probably be the first requirement. An 8 amp one is fitted but if it's not been charged for well over a year, it's probably not much good.

It was the battery that threw me...I had a 2008 Wisper and currently have 2 x 2009 models and none had a battery like that? It looked like a phylion style battery to me? the case all wrong? But I take on board what you say....

Yep, it's a Wisper but quite an old model.

If the battery has been left flat for 4 years or so it will not hold much of a charge. I am not sure whether we have any of these batteries in stock at the moment so it may take a couple of months to get one. Best check with Steve in support before purchasing.

We stopped using these generic aluminium cased batteries in 2007 when we could afford to mould a decent Polycarbon/ABS mix case for ourselves.

Otherwise it seems OK.

Ah, it fooled me - I've never seen such an early battery so I thought it was a later one. I'm easily fooled!

Hi Rog,

In the early days we could only afford this kind of case, they are cheap and can be made to any size simply by increasing the length of the aluminium extrusion. However they tend to be easily broken, can let in water and of course it's not a great idea to use such a good conductor as aluminium for the casing when working with such powerful batteries.

Most decent bikes use the same material as we do now but it's very expensive to change as any company wishing to have their own case needs to invest in an injection moulding tool.

We test each batch of battery cases by dropping them, fully loaded, onto a concrete floor from 1m, if they bounce they pass! (Please dont try this at home! )

All the best

David

Thanks for that, David. Of course an extruded aluminium case can look good which belies its cheap construction. A good few of your competitors still use them obviously for the reasons you have stated. I expect they don't put up well with such things as vibration caused by loose moutings either.
