12. INtRODUCtION tO BattERIES
Certain precautionary measures must be taken when working with batteries, in
order to prevent personal injury and property damage. you bear the responsibility
when using these batteries.
12.1 Nickel-Cadmium batteries (NC)
We recommend the following charge rates for NC batteries:
High-energy batteries: 1 - 2C; please observe the battery manufacturer's recommenda-
tions.
High-current batteries, 2 - 3C, up to 5C under extreme circumstances. Observe any maxi-
mum charge current information provided by the battery manufacturer. Check also that
the connectors and charge leads are suitable for the charge current you have selected.
12.2 NICkEL-MEtaL-hyDRIDE BattERIES (NIMh)
We recommend the following charge rates for NiMh batteries:
High-energy batteries: 0.1 ... 1 C; please observe the battery manufacturer's recommen-
dations.
High-current batteries: usually 1C, although many battery types can be charged at 1.5 ...
2C. Observe the maximum charge currents stated by the battery manufacturer.
12.3 LEaD-aCID BattERIES (PB)
• Gassing may occur when lead-acid batteries are on charge. for this reason it is
essential to provide adequate ventilation. If overcharged, these batteries generate a
mixture of hydrogen and oxygen which is potentially explosive.
Risk of explosion.
• A charged lead-acid battery is by no means a child's plaything. Batteries must be stored
out of the reach of children.
• Lead-acid batteries must never come into contact with open flames: explosion risk.
• Never forcibly open a lead-acid battery: chemical burn hazard.
• The lead-gel batteries widely used in modelling are usually of gas-tight construction,
and for this reason are less hazardous.
• In contrast, car batteries with fluid sulphuric acid electrolyte are very dangerous, both
due to the corrosive sulphuric acid and the rapid build-up of gas when overcharged.
• Never short-circuit a lead-acid battery: fire and explosion hazard.
• Never allow escaped electrolyte to contact your skin or eyes. If this should happen acci-
dentally, wash the area immediately with plenty of water, and seek medical attention.
Never place cells or batteries in your mouth, as they may be toxic.
• Be sure to observe the battery manufacturer's recommendations when charging and
discharging batteries.
