Reference

Temperature:

Common batteries like the same temperatures as humans.

They won’t work well in low temperatures.

High temperatures shorten their life.

This factor needs careful consideration if batteries are going to be relied upon in an emergency.

Store at max. 25C or less.

Replacing Batteries:

Always replace all the batteries in a circuit.

Never connect different types of battery together.

Check the terminals are clean and making good contact.

Put the batteries in the right way round.

Raised Pip to the + or red terminal.

Nose to tail, the pip of one battery to the base of the next.

Watch Batteries:

Although various elements have been used, most batteries are Silver-Oxide with Alkaline as a cheap alternative.

If you don’t have the original battery code you can go on the cross-reference guide to check for the right battery.

Lithium:

The third element after Hydrogen and Helium.

This position at one of the extremes gives it some interesting properties.

Very different types of battery are made containing Lithium.

Lithium batteries are safe if used properly, 3 - 6 volts nominal per cell.

Can be stored for some time.

Alkaline Batteries:

Zinc-Manganese Dioxide, primary cells.

Widely available.

Special versions are available that will take 1.5 volts.

Fairly high internal resistance.

Lithium Coin or Button Cells :

The Lithium cells have a larger capacity and voltage.

Often interchangeable. Not rechargeable. Never try to recharge.

3+ volts nominal per cell.

Less than 0.5 grams Lithium per cell.

Better tolerance of temperature extremes than other domestic batteries. -50

Deg. C to +70 Deg. C.

Long shelf life – up to 5 years (could last longer)

Long life in low drain service.

Zinc-Air:

A battery with Zinc as one electrode and Air as the other.

Saves carrying one electrode around as air can be collected as it’s needed.
Supplied with an adhesive tab they have a long shelf life.

As soon as the tab is removed air is allowed into the cell and the cell begins to self-discharge.

Its life will then be about four months whether it is used or not.

Zinc-Air cells offer very good value for money because of the quantities used in hearing aids.

Voltage 1.4 volts.

Alkaline Batteries:

Zinc-Manganese Dioxide primary cells.

Widely available.

Special versions are available that will take 1.5 volts.

Fairly high internal resistance.

Nicad:

Nickel-Cadmium batteries.

Rechargeable.

The archetype power tool battery.

Due to the Cadmium content this battery must be disposed of safely.
Nicad batteries prefer to be charged when they show a drop in power

Over-discharging of a battery pack risks ‘voltage reversal’, of the weakest cell.
Store as they are and recharge before use.
