Some product descriptions continue to state that maps on the devices will update multiple times a year "for the lifetime of your device". On its website, TomTom explains that "lifetime" means the "useful life"

A lovely new apartment complex in the centre of Cheltenham has 10-15 shop fronts available, every single one is empty. Quite astonishing as the apartments seem very popular.

It's more to reduce degradation - lithium batteries don't like being at <20% or >80% state of charge. If you never let them get there, they will last a lot longer.

Really like the look of this. Need to know whether it'll get software support. Also nervous about backing it, anybody know any history of the guys developing it?

From my understanding, the LEAF has a primitive battery management system compared to other EVs, including passive air cooling of the battery. Lithium batteries are fussy about temperature (they have similar temperature preferences to human

This doesn't make sense. By that logic, a lithium battery the size of a house wouldn't be able to power an LED. If you have two lithium batteries which are identical with the exception that one is double the capacity, the larger b

Yes, changing chemistries does change the energy/power density ratio. However I was referring to within a single chemistry. Hence why the higher capacity Teslas have higher performance too. An ICE doesn't get faster if you put a b

With an electric drivetrain, it's easy to go for high power. As the battery capacity increases, so does the maximum available current. This means that maximum power scales with maximum range from the battery perspective. Then (and I am

I first saw this on the Audi A1 e-tron concept; it was a 250cc wankel for the range extender. I thought that was the future when I saw it, and here I am now with a Vauxhall Ampera (Chevy Volt)!

I had this same problem almost exactly a year ago. I now have a Surface Pro 3. I wanted a decent CPU, high res screen, , good build, long battery life and small chassis. Then I chose whichever was cheapest which met those criteria. I'v
