This type of battery has an active material that cannot be restored (recharged)

This type of battery using electricity from an external source can restore the active material to its orginal or charged condition:

This type of battery are also known as storage batteries:

Two main types of secondary cells:

Lead-acid batteries produce approximately how many volts per cell:

This acts as check valves on a lead-acid battery:

This is used to neutralize the electrolyte of lead-acid battery

The state of charge of battery is indicated by the density of the electrolyte:

Specific gravity reading between 1.300 and 1.275 indicates which state of charge:

Does temperature of electrolyte affect the specific gravity

What are the two methods to charge a lead-acid battery

This is the most effective way to charge lead-acid battery:

When using this method of charging lead-acid battery, connect batteries in parallel.

This is the schematic symbol for:

Nickel-cadmium battery has this voltage per cell:

Nickel-cadmium battery charge cannot be determined by a specific gravity check of the electrolyte:

Thermal runaway or vicious cycling is a issue with this type of battery:

The electrolyte used in Ni-Cad batteries:

Nickel-cadmium batteries have an undesirable characteristic know as:

Which instrument is commonly used to measure the specific gravity of a battery electrolyte?

Which of the following is NOT a type of secondary cell?

What is the electrolyte for a lead-acid battery?

What is the neutralizing agent for a Nickel-Cadmium battery?

Due to its issue with "memory effect", Ni-Cad batteries have been replaced by which type of battery?
