I could easily have spent a fortune replacing the motherboard, the memory, the processor etc when it all came down to 2 dollar battery. What's more is these batteries are easy to get. What you need is a CR2032 available at most hardware stores like home depot and I've even seen them sold in Safeways. Of course every reputable computer lithium battery stocks store should stock them. Just check to make sure that your PC uses a CR2032 before you go to the shops!
There are several types of battery in use at the present time and each must be treated differently. There are Nickel-Cadmium (Ni-Cad), Nickel-Metal Hydride (NiMH) and Lithium-ion. Ni-Cad is old technology and hence only found in ancient handsets, so I will not be covering them in this article. NiMH batteries perform much better than Ni-Cad, typically giving 30% more talk time, but Lithium are thinner and give even higher performance. I will be concentrating on lithium facts-ion as it is the most used modern mobile phone battery to date. Check which type of battery your phone has before following any of the following.
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.
Laptop computer uses If you keep the lithium bettery stock battery in your laptop for everyday use and power it from the wall socket unplug the power every few days and let it run off the battery as a battery at capacity lasts longer than one at capacity if you don't travel with it you should remove the laptop battery when on fixed power.
The longevity of the cheap cell phone batteries you have also depend on the model of the mobile phones. The appearance of the discounted cell phone battery for cellular phones also depends on the model and make of the wireless phone that you are using.
Last, but not the least on my list is the $109,000 Tesla Roadster, a pretty hot sports car. The Roadster is an extremely fast electric car in a position to go from zero to 60 mph in just 3.9 seconds and, moreover, it may run up to 245 miles on a single charge. It is made from carbon fibre and also the power train features a custom microprocessor-controlled lithium-ion battery. The inside is incredible and features cruise control, power windows and door locks, ac, leather, touch screen featuring GPS, HD Radio, Bluetooth and several other gadgets.
