General information
Lead or acid batteries for vehicles. Standard Movement cars use only one battery with a 12V electrical system. All trucks use 2 batteries connected in series, as to make a 24V system.
Differences between car and radio batteries, and solar powered systems:
— Car batteries have a high instant-discharge capacity (for 30 seconds), which allows them to deliver a high intensity current to run the engine’s starter motor (called CCA for Cold Cranking Amp), a car battery can be damaged if discharged to less than 50% of its capacity.
— Stationary batteries (radio or solar) have a deep discharge capacity, which can operate up to an 80% discharge without damaging the battery, however, it has a small instant discharge capacity, thus cannot run a starter motor.
The voltage of a fully-charged unconnected battery is 12.8V to 13.2V. When it is discharged to 50% of its capacity, it is 11.5V, and at 80% discharge it is 10.5V. Below 10V it is dead, and can be discarded.
The most common and cheapest type of battery is the model with flat lead sections in a bath of liquid sulphuric acid. More advanced types may have a gelified electrolyte and spiral lead plates.
— Dry battery: Refers to a battery that does not yet contain the electrolyte. It is added when the battery is put in service. In this form, the battery remains in good condition during long-term storage, and can be transported without special dangerous goods packaging (the sulphuric acid electrolyte is the dangerous part). In this case, the electrolyte must be sourced locally, refer to the section below. Some dry batteries are already charged and some need to be charged before use, where there is any doubt, charge the battery.
— Sealed battery: Refers to a batter containing the electrolyte: ready to use, with or without a short charging. The term ‘sealed’ is often incorrectly used in advertising to refer to a normal battery containing liquid electrolyte and an evaporation recycling system. Sealed batteries with liquid electrolyte are not recommended.
— Non-spillable battery: This is the actual ‘sealed battery’, in addition to being the real ‘maintenance-free battery’. The non-spillable feature permits transport without special packaging under IATA regulations. It also requires no maintenance. The Optima Red Top model is recommended for cars.
Electrolyte: This is a dilution of sulphuric acid in distilled water at a concentration of around 25%. The specific weight must be 1.23 at 25°C ambient, 1.25 at 20°C and 1.21 at 30°C. Prior to purchasing, measure the specific weight with a hydrometer. Good hydrometers are graduated allowing the specific weight to be read, cheaper versions have a red-white-green scale, the reading must be in the green zone. Ensure the containers are sealed and the tamper-proof device has not been damaged.
— Exceptionally, electrolyte can be prepared from 90% sulphuric acid added to distilled water. This is a dangerous process and must be made in plastic containers with plastic instruments only. Slowly add small quantities of acid into a large volume of water . Doing the opposite would create a high-temperature chemical reaction, resulting in an acid spill.
— In some remote areas, rainwater can be collected and used directly as distilled water. It must be collected in a plastic container, never use runoff from iron sheet roofs and gutters. It can be kept for months, in the dark, in opaque plastic containers.
— Once a battery has been filled with electrolyte (battery acid) never add acid again, add distilled water only.
