Abstract

The invention relates to a battery (100) that works by regulating the power source (112) to provide a suitable voltage output so that the user’s devices/products using the battery will have a high performance among several other advantages. The battery (100) comprises a positive terminal (102); a negative terminal (112); a power source (114); and a voltage regulation device (110). The voltage regulation device (110) is operatively connected to the positive terminal (102), the negative terminal (112) and the power source (114). The voltage regulation device (110) includes electronic components that are operatively connected to each other in order to regulate an output voltage in a programmed variable level.

Claims (17)

What we claim is:
1. A battery comprising: an external surface of the battery which is substantially defined by: a housing; a positive terminal; and a negative terminal; wherein the battery has an output voltage and an output current between the positive and negative terminal in use, and wherein the housing contains: a power source; a voltage regulation device that is operatively connected to the positive terminal, the negative terminal and the power source; a programmable controller; and a current sensing circuit configured to sense the output current, wherein the voltage regulation device comprises at least one buck regulator which is configured to be activated by the programmable controller at a preset output current level, in order to regulate the output voltage.
2. The battery as claimed in claim 1, wherein the voltage regulation device further comprises at least one linear regulator configured to regulate the output voltage.
3. The battery as claimed in claim 1 or claim 2, wherein the voltage regulation device is configured to regulate the output voltage between 1.2V and 1.5V.
