Always use a well ventilated area for inverter installation. The inverter battery gets heated up during charging and operation. An airy place reduces the heating up of the battery.It also reduces the frequent water topping requirement.
After installation use battery on a regular basis. If the power cut does not occur,discharge the battery completely once every month and then recharge it.
Check the water level of battery every two months. Ensure that the water level is maintained between the maximum and minimum water limit. Always top up the battery with distilled water. Do not use tap water or rain water as it contains excess minerals and impurities which affect the life and performance of the battery.
Always keep the surface and sides of battery clean and dust free. Use cotton cloth to clean these surfaces.
Keep the battery terminalscorrosion free and rust free. If the terminals get corroded pour hot water + baking soda solution on the corrosive area or use a tooth brush for cleaning. This will remove the corrosion.Once the terminals become corrosion free, apply petroleum jelly or Vaseline on to the terminals, nuts and bolts to avoid future corrosion. Rusting and corrosion are very bad for battery performance. Rusting in terminals reduces the current flow to and from from the battery. This restricted flow of current results in slow battery charging which ultimately reduces battery life.
Be careful that the vents around battery are dust free and open. Blocked vents lead to hydrogen gas accumulation ,which may lead to bursting of battery
