    Low back up of Lead Acid Tubular Battery of Inverter

    Interested to know how to increase battery back up capacity? Check this webpage to learn more from our experts.

    I purchased Exide Battery-Inva Red 500 plus, 150 AH, 4 years ago, Inverter indicates battery is charged, but battery got discharged after 1 hour with 100 watt load. Battery water is being filled in required levels. Is it possible to increase battery back up and how?

  • To increase the life of the battery, you please see the following points and try to follow,
    1. Keep the battery terminals corrosion free and rust free. Rusting and corrosion are bad for battery performance. Rusting in terminals reduces the current flow to and from the battery. This restricted flow of current results in slow battery charging which ultimately reduces battery life and eventually effects your inverter back up. If the terminals get corroded pour hot water + baking soda solution on the corrosive area or use a toothbrush for cleaning. This will remove the corrosion. Once the terminals become corrosion free, apply petroleum jelly on to the terminals, nuts and bolts to avoid future corrosion.
    2. It is important to charge the inverter batteries correctly in order to maintain the backup. 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.
    3. Check the water level of battery every two months. See 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.
    4. Change the batteries of the inverter if they are worn out. After some time the batteries lose their capacity and reducing the backup. Buy good quality batteries that will last longer and also guarantee the correct charge storage capacity. Poor quality batteries fail prematurely and do not offer sufficient backup. Maintenance free or sealed batteries are best suited as these won't leak the electrolyte. There are other types of batteries as well as lithium batteries which can be used for back up. Tubular batteries are the most efficient batteries. They have a complex design, great efficiency, longer operational life and low maintenance.

  • Eventhough some people believe that tubular inverter batteries do not need maintenance, they also need some regular attention and care. The battery water needs to be changed .It should not be allowed to reach the rock bottom anytime. The battery should be kept in a ventilated place. It should be periodically cleaned to remove dustand dirt. But care should be taken not get shock or make sparking.
    In case you are not experienced or careful, you may call a technician.
    First get the battery ends and lead wires loosened, cleaned and refixed. Ensure battery water is full to the level allowed. Let the technician check the input and out put by necessary tools and appliances.
    Even after all these, if back up does not stay, then it is time to change the battery.

    For future guidance when you do not use the inverted for long(when you go on long vacation etc) disconnect battery from inverter. Reconnect after return and charge full before use. Never allow to fully discharge. Do regular water filling and keep in a place where ventilation and approach are easy.

  • The maintenance of lead-acid batteries is very essential for its longevity. Regular water topping and cleaning of terminals to get rid of the deposits is a must in regular intervals. Due to terminal degradation, it sometimes so happens that contact resistance is generated which affects the charging current adversely. If these batteries are not maintained properly they give service for hardly 1-2 years and require replacement.

    Even after maintaining the battery it has a life of 4-5 years after which it does not give good results and discharges quickly and does not support the inverter to produce emergency light in case of mains electric supply failure. In such case, there is no way except to change the battery.

    Knowledge is power.
