First on my small list may be the Coda electric car available with a 4 seats capacity and powered by a 728 cell cobalt ontario canada-ion phosphate battery. The vehicle includes a range of 90-120 miles and can achieve a maximum speed of 80 mph. It comes with an interesting warranty: 3 years or 36,000 miles. An interesting fact is the battery which equips this car is covered for 8 years/100,000 miles. If you are interested in buying this electric vehicle you should know that the prices are around $37,000.
I run a PC repair business in Vancouver. I always tell people who call with clock problems to check their motherboard battery first before calling me round. For most people it's easy to lithium facts check and easy to replace. I don't want to make money from fixing something so simple.
Even the best solution has internal resistance, which it discharges through over time, thus that optimal 40% capacity drips away. Another thing Lithium-Ion cells absolutely loathe apart from heat and being overcharged is being fully discharged.
But that means that laptops need to have bigger batteries and bigger batteries mean bigger size. Laptops won't be portable and convenient to carry in this case. That's the reason why laptops have compact batteries that gives it a sleek look. But these batteries don't lithium bettery stock have good battery-life.
Briefly relating back to overall size... many lithium 18650's will differ ever so slightly in length (measured in millimeters). This is mainly due to an added protection circuit. The circuit helps to prevent the battery from over-discharging, since Li-ion cells can easily become damaged if their power is drained below a particular voltage. The protection circuit also prevents the cell from being over-CHARGED as well. These cells are very sensitive. They must be handled carefully, gently, and as described above, must never run-down too far, or be charged over and above their threshold. They can actually explode if severely mistreated!
There are a couple of more considerations about choosing your cell phone battery which we cover with a later post. And don't forget the holidays are coming up so make sure you take a look at various face plates and extra batteries to enhance your gifts!
