- Use only a damp cotton cloth for cleaning purposes. 

- There is no technical reason for limiting the number of strings but for practical installation reasons, it is recommended not allowed to exceed 3 strings in parallel especially if the battery is 

used in high discharge rates (backup time less than 15 mins)

(1) When cleaning the batteries, use soft cloth only. Use of organic solvents such as gasoline or thinner, and application or adherence of oil to the batteries must be avoided. Do not clean the 

batteries using dirty or oily cloth. Also contact with soft polyvinyl chloride or the like must be avoided.   

(2) Batteries may generate inflammable gas in some cases. Do not expose them to flame or excess heat. Do not short batteries.   

(3) Do not attempt to disassemble the batteries. Avoid contact with sulfuric acid leaking from broken batteries. If acid gets into contact with clothes, rinse the area generously with water. If 

acid gets into contact with your skin or eyes, generously wash the affected area with clean water, and consult a physician immediately. 

(4) Batteries explode if put into the fire. Never dispose of batteries in the fire.   

(5) Mixed usage of batteries differing in capacity, type, manufacturer or history of use (charge/discharge operation) must be AVOIDED for this may damage the batteries and the equipment 

due to the difference in characteristic values.   

(6) While our batteries are exceptionally dependable, we do not recommend use in life support medical applications unless there is an alternate battery or back-up power supply. 

(7)Acid leakage and unusual appearance must be avoided before switching on, noting open circuit voltage. 

(8)There must be appointed man operating for 24 hs after switching on to solving potential problems in time, noting voltage and current. 

(9) When the batteries come to their end of life, discharge duration time becomes shorter. Finally, batteries lose their available capacity by internal short-circuit and/or dry out of electrolyte. 

Therefore, please consider the design of the charger for the battery with some care regarding above battery damage modes, such as short-circuit protection for out put.
