Exam 13: Batteries

A ______________ is used to check specific gravity of a lead-acid battery.

An applied voltage higher than the emf of one cell can be obtained by connecting cells in ______________.

What type cell has the ability to deliver high current and be cycled many times for recharging?

A ______________ cell is a storage cell that can be recharged by reversing the internal chemical reaction.

A single ______________ cell is a piece of plastic between a couple of pieces of carbon plates that are sandwiched between two end plates acting as electrodes.

How many times more energy can a lithium cell provide than the equivalent carbon-zinc cell?

Primary cells cannot be recharged.

What cell has an output of 1.5 V and is available as either a primary or secondary cell and lasts much longer than a carbon-zinc cell?

The device for converting chemical energy into electrical energy is sometimes called a galvanic cell.

A generator with a very low internal resistance is considered a

A secondary cell is also known as a

For more current capacity, the battery

A method in which the charger and the battery are always connected to each other to supply current to the load is ______________ charging.

Where is a common place to store small nonrechargeable batteries in order to prolong battery life?

A ______________ is a group of cells that generate energy from an internal chemical reaction.

The electrolyte, cost, stability, and long life are important for the construction of commercial batteries.
