Battery Tips
Industrial Lead storage Battery
Industrial Lead Storage Battery is divided into cheap low-priced MF battery and high priced VRLA battery.
(VRLA : Valve Regulated Lead Acid battery ; sealed type maintenance free battery)
- Industrial lead storage battery(=industrial battery) is using 12V standard(official) voltage battery (series connection among 6 cells
of 2V batteries inside) or using bank(bundle) type series connection among many high storage 2V cells.
- This battery is divided into two types one is GEL type which has jelly like electrolyte inside the other is AGM type which has AGM
(Absorptive Glass Mat) membranes.
- Industrial battery used in the place where need lots of discharge because it has thick lead plate. However it is inappropriate where
using lots of electricity in a short time because of narrow lead plate surface. It can cause current instability because the lead plate
melting to sulfuric acid solution time is later than current demand quantity.
- Though it has a little capacity but it can be used for a long time, high-priced battery is used for UPS(emergency electric) or standby
power and low-priced one is used for electric handcart or camping car.
- Industrial lead-acid battery can be judged in order of RC(reserve Capacity) value, Internal Resistance and Voltage.
Deep Cycle Battery
This battery is mostly used in electric forklift, golf cart and so on which is moving by battery power and most of them are
high-priced maintenance battery.
- It used most of its charged energy in that day and then charge again, that is it used by Deep Cycle. Because its thick and wide lead plate, it
can deep discharge so it can do discharge 80% or more of its storage and charge it more than hundreds of time and called deep cycle battery.
- Because of its thick and wide lead plate and available for deep discharge it has long life span and it is used in variously.
- Deep cycle battery is used 6V standard(official) voltage battery (series connection among 3 cells of 2V), 8V battery
(series connection among 4 cells of 2V) or bank(bundle) type series connection among high storage many 2V cells.
- Deep cycle battery is used in electric forklift, golf cart, tower wagon and so on which using lots of electricity.
- In these days industrial UPS battery is using Deep cycle method to supplement low-priced industrial lead storage battery's weakness.
- Deep cycle battery can be judged in order of RC(Reserve Capacity) value, Transparency of electrolyte, Gravity and Voltage.
SLI (Car-Start) Battery
Usually Car-start battery (= Car Battery) called MF battery (Maintenance Free battery) means maintenance free.
- Car Battery is normally used 12V standard(official) voltage battery. (series connection among 6 cells of 2V batteries inside).
- Lead-acid battery for normal car is SLI battery normally used for Start, Lighting and Ignition.
- Car battery is made for quick discharge and quick charge because most cars using heavy electricity when their start and charge is
done right after start.
- SLI battery is consist of structure for using heavy electricity in a short time so it is made by wider surface of the lead plate sunken
in sulfuric acid solution for that. However the lead plate is so thin in this feature so it can be harmed easily by external shock when it
discharged or charged for a long time.
- Car battery can be judged in order of RC(Reserve Capacity) value, CCA(Cold Cracking Ampere) and Voltage.
The way of maintaining maintenance battery
- After regenerate/charge of battery, you should check the electrolyte and supply more distilled water if it is not enough. (Do not put sulfuric acid)
- Supplement of distilled water always has to be done after regeneration/charge. If you supply distilled water to discharged battery inner electrolyte
can be overflown.
- If the battery temperature is over than 46.1 you should stop the work and do the work again after cooling the heat.
- You should avoid flame or metal from the battery socket, do not smoke near the battery when regeneration/charge of it.
- When you discharge the battery you should do to the final discharge voltage. If the battery voltage is fallen under the final discharge voltage it can
have a problem.
- If you store it in winter or long period, you should do it after charge.
(Inner lead plate is thick but the surface is not wide.)
(Inner plate is thick and the lead plate is also thick)
(Internal lead plate is thin and wide)
