In order to get full performance of the Valve Regulated Lead-Acid Batteries (Commonly known as VRLA Batteries), please read information below carefully when using or installing these batteries.
aApplication Range
User guidelines for “PORTALAC” series VRLA battery is shown:
In order to use the batteries safely, it’s very important to use, maintain and inspect the batteries correctly. Please read this user guidelines manual and cautions carefully before using. If you do not fully understand this manual and cautions, please directly send your questions to our company. Wrong application will lead the batteries to acid leaking, heating and explosion as well as body/facility damaging.
Batteries would not perform well with wrong equipment. Please read the manual and cautions of the equipment too.
In this manual, the levels of danger are shown in below.
aDangers in Application
Please do not store the battery in a closed environment, shall keep it away from fire sources. If not tend to cause an explosion, fire, facility damage and body injury. Moreover, battery may emit hydrogen gas.
Metal tools such as torque wrench shall be insulated with vinyl material. If not, heat and spark can be caused by short circuit, which will damage battery and even cause an explosion or fire.
Do not connect the positive terminal and negative terminal with wires or other metals. Furthermore, never contact metal tools such as torque wrench with points of different voltages. Doing like this may cause a rise in battery temperature and emit hydrogen. That will cause acid leakage, fire and even an explosion.
aWarnings in Applicationshock.
Please do not use the battery in a moist environment or immerse it in water, doing this will cause battery acid leakage, electric shock and fire.
Please make sure to connect the proper polarities of the batteries. Connecting wrong polarities can cause fire or damage to the equipment.
Please do not weld battery terminals and never reverse battery terminals when charging or it will cause acid leakage, heating and explosion.
Please do not use/leave the batteries near transformers, heat sources, or inside an automobile under the sun, and never place them under direct sunlight, near heater, fire or in any other spaces of high temperature. All of these will cause acid leakage, heating and explosion.
Please do not decompose, reconstruct or destroy battery that will cause acid leakage, heating and explosion.
Please use a specialized charger to charge the battery, and follow the specified charging terms. Charging under different conditions will cause the battery to leak fluid, heating and emit hydrogen even cause explosion.
Battery contains diluted sulfuric acid. If the acid leaks out and gets onto your skin or clothing, please wash it off immediately with clean water. Additionally, if the acid splashes into your eyes, please wash them with large volume of flesh water and get immediate medical attention. If acid splashes into your eyes, which may cause a loss of eyesight, and when it gets on your skin, it will cause a burn on your skin.
Do not install battery at an angle over 90 degrees, as this will cause battery leakage, fire and explosion.
Do not clean battery with any dry fabric or duster can cause static electricity, which may cause an explosion. Please use a cloth that contains an adequate amount of moisture.
Battery container material is resin, therefore please do not use any type of organic solvent (such as gasoline, lamp oil and vaporized oil etc) to clean the battery surface. Those materials can lead to battery container/cover cracking.
Please replace the battery when the time indicated on equipment or in owner’s manual. Usage beyond expiration date will cause acid leakage due to container damage and even can result in an explosion.
When the connection voltage from the battery in series is 45 volts or above, please wear protective article such as rubber gloves. Operation without enough protection can lead to electric.
aCautions in Application
The temperature ranges for batteries usage are listed as below. Usage outside the following ranges will shorten battery life and lower its performance level, and may cause acid leakage, fire and explosion.
During charging ：0～40℃
During discharging ：-20～50℃
During storage ：-20～40℃
Do not use the battery out of its application range. Doing this will cause acid leakage, fire and explosion...etc.
aSuggestion in Application
Please do not use intermediate stoppers when you are using batteries in series connection.
Please do not over discharge because it will affect battery life, takes a whole day to recharge once over discharged, because over discharge relates to final discharge voltage. For discharge final voltage, please refer to this text.
In case there is temperature difference between batteries because battery installed location, please control the difference within ±3℃.
Please control the battery connection voltage under 100V in series connection and avoid parallel connection. For standby use, if parallel connection or over 100V in series connection is needed, please follow the terms instructed as below. Please make sure to use it under 500V and for parallel connect less than 3 sets of batteries.
● Please use over charge preventive circuit
● Please use protection circuit that can stop over charge automatically when battery temperature become higher, or use charging circuit that can change charge voltage by temperature coefficient with -3mV/°C cell (Especially -3 ~ -5mV/°C cell in rapid charge) details showed as table 5.
● When place batteries, please keep 10mm away from surroundings and other batteries. Keep proper ventilation as well.
● Please set resistance of each battery to equivalent.
Repeated over discharging will shorten the battery life，so please follow charging specification
aOther Cautions & Suggestionsn
When you choose battery, please make your decision after checking rated value and characteristics in this manual or product catalogue. Please ask us for specification when needed.
