Li Battery lasting 10,000 cycles?

Probably not relevent. Our batteries use carbon anodes since copper/tin anodes have not developed to the point of suitability for our current demands at present.

Also it's the cathode life, not the anode life that limits our batteries and that's much shorter due to the high current demands of our motors.

All rechargeable batteries last for a very long time if used within the central area of charge at low current demands. That's how lithium and NiMh satellite batteries operate for ten years of daily charges without failure.

Drat! I knew there would be something. I'll continue to keep my salt cellar nearby.

:D. Sadly there always is where batteries are concerned.

That's why after over two hundred years of excited claims of advances, the 19th century lead acid technology is still used for the largest high current battery application, starting our cars and other vehicles.

I have been thinking why car makers still use lead acid batteries and could it be that as long as you don`t keep running them down and they get that regular charge evertime to start the car that makes for an ideal. whereas with our bikes we tend to run the batteries down to maybe half power everytime we use them. of course weight isn`t such a problem in a car like it is on a bike.

I`d be very interested to do some testing with lead acid batteries on the bikes. Have you tried them?

Never drove a car, dought i'd be accepted for a lisence, but was thinking of the size of the acide lead batterys in cars, Huge.

Think I'll emigrate to the Netherlands, it's all flat there, electric bike heaven ...that's for the long distance, otherwise some good exercise will do on the flat.
was wondering, as ive left my bike in the living room, and there is such little space in here, it isn't far from the heating, I have no garage, I keep the battery upstairs under the bed, trying to find the coldest place, but as I haven't charged it for over a year I think its history.

I did have an acid lead bike, I bought it from a bike fair in Hastings, it was £350, and seemed to go nicely up the paths, where the park wasn't that steep, I got nearly a year out of that bike, and enjoyed it, I don't recall the make, but I know they stopped making them, I sold it back to the retailer for £100 less than I bought it, for not bad for a years enjoyment, and exercise, I did have to walk it up the hills, but once down town, by the sea, I felt as free as a bird.
