How Do You Build A 90 Volt Rechargeable Battery?
Batteries are a convenient way to deliver electricity to portable appliances. Although they are available in many voltages, the basic battery cell produces just 1.2 volts to 3.6 volts. Larger batteries consist of groups of these low-voltage cells linked together. The ways in which you link them determine whether their voltage or current capacity is increased. To produce a 90-volt battery, link a number of smaller batteries together in series. Consider the eventual use of your 90-volt battery. If it needs to deliver a high current, construct it from batteries with a high amp hour rating, such as lead/acid batteries used in vehicles. If you need only a low amp hour rating, use batteries such as the common cylindrical “D” series batteries designed for use in portable lighting. Calculate the number of rechargeable batteries you need to create a 90-volt battery. Divide 90 by the voltage of the batteries you have selected for the project. For example, if you are using 6-volt lead/acid batter
