Don't you just hate it when your mobile phone battery wont even last until you get home? How it goes flat every time you talk, use the camera, listen to a song or browse the internet? It really is very frustrating to have a weak battery that cannot hold much power to last a day with average activity. Reasons for a weak battery are the misuse of the battery and the lack of proper maintenance. The capacity of a mobile phone battery is measured by its standby time and talk time. It is measured in milli-amph hours (mAh). Rechargeable batteries have three main types, Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH), and Lithium Ion (LiIon). Lithium Ion (LiIon) batteries are what you find in most mobile phones and in order to preserve the battery you might want to follow these steps.
 

When the hybrid engine is was ist kobalt in parallel both engines can propel the car alone or together. A good example would be Toyotas' Hybrid Synergy Drive (HSD). Capable of being propelled at low speeds by the electric motor, the gas engine takes over at higher speeds. This allows both engines to perform in their optimal situation.

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.

The last thing to start tinkering on is the rate of fire. The biggest thing that will determine your ROF is the battery voltage and the amount Milliampere-Hour rating (mAH). Some of the best batteries for increasing ROF are the LiPoly batteries (Lithium Polymer) but you should not use these types on out of the box guns. When preparing to use the Lipoly battery you need to make your internal components are reinforced and upgraded where they need to be.

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.

The basic rule of getting a replacement battery is that it should have the same voltage as the original. An 18V drill cannot run on a 12V battery. It can only run on a 18V battery. The other thing is that the physical packaging of a battery can be different from company to company. A 12V Ryobi battery may not fit into a 12V Makita cordless drill unless the battery has the right physical dimensions. So make sure the replacement battery looks the same as the old one before you order it. Also, if you are looking for a replacement battery of the same voltage rating and by the same company, know that battery technology is changing rapidly. An 18V lithium-ion battery has a different physical packaging than a NiCad 18V battery.

For jobs where the batteries are required to be light weight as well as being reusable, then lithium batteries are ideal. But if a battery is needed to be very reliable or to remain unused for a long time then they might not be the right batteries for it.
