Battery Care
& Maintenance
A) STORAGE
1. Always rotate your stock. Practice FIFO (First In, First Out). Batteries slowly lose their charge and good stock rotation stops the batteries going at in storage and makes sure that the customer buys a good quality battery.
2. Store batteries in cool, dry, well-ventilated areas.
3. Store batteries in an upright position.
4. Store batteries on racks or on pallets, not on the oor.
(Small stones or sharp points on a concrete oor can
damage the base of the battery and cause leakage.)
5. Make sure handles are left in the at (down) position.
Upright handles are more likely to be damaged.
B) MAINTENANCE OF STOCK
Wet-Charged Batteries
1. Check the open-circuit voltage of the batteries in your
stock every month using a digital voltmeter or a multimeter. If any have a voltage below 12.50V (6.25V for 6V batteries), perform a refresh charge.
C) COMMISSIONING
Wet-Charged Batteries
1. Do not supply a battery to a customer (end-user) if the voltage is below 12.50V (6.25V for 6V batteries). Charge any batteries with voltages below these values.
2. We recommend you check the condition of the battery before selling it using one of the methods described in Section G.
NOTES: PLEASE READ BEFORE ADJUSTING ACID LEVELS
• Do not top up to the maximum level, a battery that needs charging (Levels rise on charging). However, if the levels are below the tops of the separators, top up with distilled or de-ionised water until the separators are just covered.
• Adjust to the maximum level after the battery has stood for at least an hour after charging.
• Never over ll a battery. (The acid may come out of the vent-plugs when the battery is being charged).
1. When the battery is in service, the electrolyte levels should be checked and adjusted to the levels given.
2. Use only distilled or de-ionised water for topping up. (Sulphuric acid should never be used except for the initial lling of a battery.)
3. If the battery has a maximum level line on the side of the container, ll to this maximum level.
4. If there is no maximum line, but there are lling tubes projecting from the bottom of the lid, ll to the bottom of the tubes.
5. If there is not a maximum line nor lling tubes in polypropylene batteries, ll to 7mm (0.25 inches) below the bottom edge of the lid-skirt.
6. If there are no lling tubes in hard-rubber batteries, ll to 15mm (0.5 inches) above the tops of the separators.
7. Sealed batteries do not require maintenance.
Car And Commercial Vehicle Batteries
1. Select the speci ed battery from the application section of this catalogue.
2. On 24 Volt systems, or when 2 of 12 Volt batteries are tted in parallel, both batteries should be replaced at the same time. Failure to do this will result in greatly reduced battery life for the new battery that has been tted. When batteries are joined in series, the negative terminal of one battery is connected to the positive terminal of the other, giving a total voltage of 24 Volts. The ampere-hour capacity of the system is the same as that of the individual batteries. When batteries are joined in parallel, the positive terminals of the 2 batteries are connected together, and the negative terminals of the 2 batteries are also connected together. The voltage of the system remains unchanged
at 12 Volts, but the ampere-hour capacity of the system is double that of the individual batteries.
Leisure Batteries
1. Use the battery with the performance and size recommended by the equipment supplier.
2. We recommend that a leisure battery in a
cycling application should be sized so that it is not normally discharged to more than 50% state of charge. This will ensure that the battery gives a
good life. For example, a load of 3A for 10 hours will discharge a battery by 30Ah. If this represents 50% state of charge, we would recommend a 60Ah battery.
1. Switch off all electrical loads and remove the ignition key. 2. Disconnect the earth-connector rst. (This is normally
the negative on modern vehicles). This can result in the loss
of memory settings; please refer to the vehicle handbook. 3. Disconnect the live-connector second.
4. Remove the hold-down clamps.
Preparation Of A Battery For Fitting
1. Check that the battery has the correct polarity for the vehicle.
2. Check that the battery has the correct height for the vehicle. (If a battery is too high, it can short out on the bonnet or the bottom of a seat, or it can damage the bonnet).
