Are the new crop of Li-ion battery tools inherently dangerous?

There is nothing inherently more dangerous about Li-ion or Li-poly than NiCd and NiMH.

Many of the problems that have hit the news have been due to manufacturing faults. Because the cells in these batteries are different from the standard cylindrical configuration, manufacturers have had to re-tool in order to manufacture them. This is the first major re-tool in a very long time, and it's just taken a bit of time to iron out some difficulties.

The advantages of Li-ion are huge - much higher power density, no heavy metal content, great charge-discharge characteristics, the list goes on.

For a glimpse of what can be done with Li-ion, take a look at this:

best!"

Pity we never invented the metric system isn't it. Pity someone never told their advertisers. I would never consider looking seriously at an ad that gave the specs in French. Nothing against the French of course.

But if the morons overlooked the fact that we drive miles in this country and still consume fuel by the gallon despite what the arses in government want us to do, I might be looking at a car designed to travel on the wrong side of the street for my tastes.

No. The problem is specific to laptop batteries, where extra thin separators are used to squeeze more capacity into a small space.

It does give the fuel consumption as 80 mpg. And where do you buy fuel by the gallon these days. I measure my fuel consumption in miles/litre.

Very impressive, would love to see it go :)

My only worry is there are NO mechanical brake. Fully reliant on software/hardware for the regen braking!!!!

Don't worry about that..... Grunff wrote the software. He's very good :-)

The message from snipped-for-privacy@care2.com contains these words:

Not just laptops. Model aeroplanes have had a few go pop, too.

And the ones for cameras, phones and small torches too (Cr123). I understood it was the technology not the actual design which is sensitive.

I've even read of problems with non rechargeable Li-ions

I note the blocks under the tyres in the top picture :-)

And I've had difficulty getting such posted from the US .. (laptop battery).

And for the car .. 80 mpg indeed .. ;-)

Oh and .. "Emissions - Zero for 4 hours" .. so charged by hydroelectric then?

;-)

All the best ..

Who cares - have you seen how fast it is??

If you flatten the battery and have no fuel, all it needs is a tow for 1/2 mile or so and the wheels turning will charge the battery, they you get home.

As long as you only live a mile or so away, of course

A simple overview:

So it would need to be towed by an F1 car then (most trucks only being ~450hp).

And they are environmentally friendly aren't they? ;-)

All the best ..

We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember "Doctor Drivel" saying something like:

Really? Creates energy does it?

FFS.

I suppose it fills up the petrol tank too.

One of the correspondents who contributes to Autocar runs a Lexus GS300, and borrowed the same car but the hybrid version. Got 28 mpg with it during his usual commute across London. Exactly the same as his own car. It's about time they sorted those false MPG claims - and also the false low CO2 output company car tax is based on...

Yep.

It does?

Oh no the naive intervene again. Will you please eff off as you are an idiot.
