For this you will need to know the make and model number of your power tools; if you don't know this offhand or don't have the necessary paperwork, check the inside of your drill's battery compartment while the drill is off and unplugged. There you should find the model number, along with some other information. You may also find the part number of your power tools battery, located on the casing of the battery itself.
When buying a power tools battery, you will probably only have one or two choices that fit your computer. Choose the battery with the longest life available for your computer. There are several different kinds of laptop batteries; because the technologies of each are very different, a drill must be designed specifically for the type of battery it uses. Most power tools are only designed to use one type ofbattery technology.
Voltage is the measure of the strength of an electrical source (for a given current level). Rechargeable BOSCH batteries for power tools generally contain cells with a voltage of 1.2V, 1.5V or 3.6V. Manufacturers utilize these cells to produce batteries that can have a voltage of anywhere between 3.6V and 48V. Generally speaking, the higher the voltage, the heavier the battery will be, and the more power it will be able to output.

Once fully charged, the maximum runtime of a cordless tool is largely determined by the battery's amp-hour (Ah) value. In essence, this value represents the fuel tank of the tool. The larger the fuel tank, the longer the tool will operate for. Amp-hour values will generally range from 1.3Ah to 3.3Ah, depending on the tool's intended applications (i.e. light or heavy work). As this capacity increases, batteries will also become heavier and will take longer to charge.
'Memory effect' in some batteries can also seriously affect their runtime. This is the main reason why batteries last for very short periods of time, even right after they have been charged. The term 'memory effect' is a condition found in some rechargeable batteries that results in the reduction of their capacity.
Another factor that affects runtime, but one that isn't related to batteries, is the efficiency of the tool itself. An efficient tool will transfer nearly all of the power from the battery to the business end of the tool. An inefficient tool (generally tools of lower quality) will waste excessive power simply transferring energy to the business end of the tool, which will severely decrease the runtime of a battery.
Lithium-ion (Li-ion) batteries (BOSCH GOP 10.8 V-LI li-ion battery) are the newest and most advanced type of battery for power tools. They have many advantages over both Nickel-Cadmium and Nickel-Metal Hydride, but still have their shortcomings. Some manufacturers have addressed these shortcomings by introducing elements such as Phosphate, Manganese and Cobalt into their battery's chemical composition. High quality brands will also feature electronic cell protection to stop the battery's cells from overheating, and from being overloaded and over-discharged.
