Battery indicator
Friday, March 16, 2012 by skemarangkaian
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.
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.
