Sealey SUPERSTART520 - Manual (Page 3)

4.3.2. superstart620.V5 (see fig.7) select charge level 1,2 or 3 using the rotary switch situated above the timer.
4.3.3 once you have checked that the charger is correctly set up for the current situation, switch on the power.
4.3.4. check the current delivery to the battery by reading the ammeter on the front of the battery charger (fig.4)
ammeter face may vary by model). Initially, there will be a high rate of charge which will slowly decrease
according to the capacity and condition of the battery.
4.3.5. When fully charged the ammeter reading should be close to “0” and the electrolyte in the battery should begin to
gas. stop charging to protect battery plates from oxidisation and damage.
4.3.6. switch charger off and unplug from mains power. Disconnect the power clamps, clean the charger and
store in a safe, dry area.
4.3.7. replace the battery electrolyte cover or caps. Wipe up any splashes or spillage (remember the electrolyte is a
corrosive acid). return the battery to the vehicle, secure according the manufacturer’s instructions and
re-connect the power leads. check to ensure all tools are removed before closing the bonnet.
4. OperatINg INstructIONs
4.1 preparatION It is important to correctly prepare for charging - follow section 1 safety requirements and, especially when charging
battery in situ, any vehicle manufacturer's instructions. check that capacity of battery is compatible with charger output.
4.1.1. check battery to ensure the nEGAtIVE & PosItIVE terminals are clearly identifiable before removing the battery from the vehicle.
4.1.2. Disconnect and remove the battery from the vehicle and place in an appropriate safe area ready for charging.
4.1.3. remove the battery electrolyte cover or caps to allow the gases produced by charging to escape.
4.1.4. check the electrolyte fluid level in the battery is above the plates. If not, add distilled water to cover them by 5 - 10mm.
Do not touch the battery fluid as it is corrosive.
4.1.5. the correct charging status of the battery may be determined by use of a hydrometer which measures the specific density of the electrolyte
the following information indicates kg/l at 20°c: 1.28 = Fully charged 1.21 = half charged 1.14 = Fully discharged battery.
 WarNINg! Be cautious and vigilant as the electrolyte is highly corrosive sulphuric acid.
4.2. cONNectINg charger tO BatterY
Ensure the battery charger is unplugged from the mains power supply before connecting power leads to the battery.
4.2.1. set the charger voltage to match that of the battery: i.e. 12 or 24 volts by moving the cable to the appropriate terminal.
4.2.2. check the charger clamps and battery terminals to ensure they are clean and free from oxidation.
4.2.3. connect the charger PosItIVE (red or +) lead to the PosItIVE (+) terminal of the battery and the nEGAtIVE (Black or -) lead
to the nEGAtIVE (-) terminal of the battery.
4.3. chargINg the BatterY
connect the charger to the mains power supply and set the rate of charge according to your model type as follows:
4.3.1. superstart520.V5 (see fig.6) set the mode switch (next to the on/off switch) to the ‘charge’ function indicated by the battery symbol.
Low charging rate: - select MIn & 1
Med charging rate: - select MIn & 2
High charging rate: - select MAX only (please note that when MAX is selected the switch marked 1 & 2 is over-ridden.)
the timer can be used in conjunction with the MAX setting and may be set for a charge time of up to 60 minutes. When the selected
time has elapsed the current will be switched off. for untimed functioning leave the timer knob set on ‘normal’ charging.
 WarNINg! ensure you have read and understood all safety instructions before using the charger.

fig.6 fig.7
notE: If charger is connected to a fully charged battery the ammeter will show a low charging output. no charging is necessary.
Do not continue to charge a fully charged battery, as this will damage the battery. Do not leave a battery on charge unattended.
4.4 seaLeD BatterIes
4.4.1 charge a sealed battery very slowly, carefully monitoring the voltage across the battery terminals using a normal tester.
4.4.2 When the battery terminal voltage reaches 14.4V for 12V batteries or 28.8V for 24V batteries, stop charging.
4.5 MuLtIpLe chargINg
 WarNINg! DO NOt simultaneously charge different types of battery or batteries with
different capacities or levels of discharge.
4.5.1 simultaneous multiple charging should be carried out in series, since this enables monitoring
of the current circulating in each battery. see fig.8. notE: If two batteries with rated voltages
of 12V are connected in series, move the positive cable to the 24V terminal.
4.5.2 When fully charged, the ammeter reading should be close to “0” and the electrolyte in the
batteries should begin to gas. stop charging to protect the battery plates from oxidisation and damage.
4.6 rapID charge
the superstart620.V5 has a rapid charge function which is controlled by the 60 minute timer provided. rapid charging takes
place at a pre-set rate which is one step higher than the highest charge rate available during normal charging. to initiate rapid
charging turn the timer to the required charging time in minutes and turn the rotary selector switch to the rapid charging position
indicated by a ‘hare’ symbol (see fig.5). When the pre-set time has elapsed the current is automatically switched off. turn the
rotary selector switch to the ‘off’ position.
