Battery indicator

In this part of the investigation in a circuit of battery
indicators , this is arise such alarm sound or light up when the battery already weak, so that needs to be replaced or re-charge.

Circuit of Battery indicator

Note:

voltage used is 12 volt
Low voltage warning flow: 15 mA
Alarm tone can be changed with the R7.


Tips Merawat Battery basah

• Keep the electrolyte in the battery between the lower level and upper level lines. Check it at least once a month.
• Short of electrolyte will cause sulfation to the elements and reduce the battery's performance in generating electricity flow.
• Use distilled/demineralized water only for battery filling. Avoid using tap/well/mineral water as they may contain metal ions or organic substances that lower the battery's performance and its life.
• Clean the battery's surface and keep from any electrolyte spill.
• Clean the terminal surface using a little grease/lubrication to prevent from oxidation or fungus.
• Do not connect the positive and negative terminal using a piece of wire as this will damage/terminate the connection between the terminals and elements.
• Make sure the wire connection to the terminals is tight enough. Loose connection causes sparks, it may cause the battery explodes.
• Cover the positive terminal's surface using isolator (plastic/rubber) to avoid short circuit to the vehicles body.
• Cover the battery's surface with plastic/rubber sheet to protect it from dust/dirt blocking the vent holes.
• Check the vent holes periodically. Blocked vent holes may cause the battery expand and eventually will cause explosion or leakage.

Tips Recharge a battery
Quick-charge recharging.

• Make sure the charger is at OFF position
• Attach the clips (red + and black -)
• Connect the charger to the electricity point
• Set the timer
• Set the recharging flow (maximal equivalent to the battery's normal capacity).
• These steps apply only to an emergency condition.

Normal recharging.

• Make sure the charger is at OFF position
• Attach the clips (red + and black -)
• Connect the battery in parallel fashion
• The recharge flow is selected for a battery with small capacity
• Recharge flow volume is 1/10 of normal capacity
• Recharge time: 3 times constant voltage.

After recharging is completed.

• Turn off the charger
• Release the clips on the battery
• Release the wire from the electricity point.
