5 top inverter battery problems

4 things that are harming your inverter battery 

Inverter batteries are an inevitable part of inverters. They store the electricity which can be later used to power the home during the long and irritating power cuts. We are well aware of the functioning of an inverter battery and we know that we have to take care of it to prolong its life.

Here are the few reasons that are leading to damage to your inverter battery:

1.Lack of regular maintenance 

As we all know, regular maintenance of the inverter battery is really important otherwise it will stop working. So start taking care of your inverter battery like checking for any damage, topping with water, keeping it in  a ventilated place away from fire and water. 

If you carry out proper maintenance it will ultimately lead to a longer lifespan of the inverter battery.


There corrosion occurs at two places- one at the grid and the other at the terminals.

a)corrosion at the grid:

Corrosion happens mostly  in the grid where the lead gets softened and shed from the grid. It is an evitable thing because the reaction between the plates and sulfuric acid is very reactive. This corrosion leads to reduced efficiency of the battery. It is mostly a problem in deep cycle batteries as they are designed for deep discharging unlike the starter batteries which are used for starting up the vehicle.

b)corrosion at the terminals

After a long usage corrosion of the terminals occurs. It looks like white powder on the terminals. It leads to slow current flow thus hampering the working of the battery.

Terminal cleaners are available to clean off the rusting or corrosion and after that you can apply petroleum jelly on the terminals and bolts to protect it. 

3.Over Deep discharging

Although inverter batteries are made for deep discharging but care has to be taken so that frequent deep discharging does not happen. When deep discharging happens it means that the battery has been used till its full capacity. Actually we are talking about over discharging which means the internal resistance of the battery has increased which makes recharging of the battery difficult.

Every battery has a cut-off voltage and discharge rate. They both are inversely proportional to each other.If the cut off voltage is low then the discharge rate will be high. Keep in mind that once the battery is overly deeply discharged then it can’t be again.

4.Loose connections

Always check loose connections on the batteries. If you notice any,get them repaired at the soonest possible. The connection of the battery to the inverter could be loose or the battery to the power socket could be loose which may lead to sparking or more damages.

Get the connections checked at the earliest to avoid any further damage to the battery.


The good thing here, most of the problems can be avoided with timely intervention and precautions. Follow the following tips to extend the battery life:

1.Avoid overcharging and deep discharging

2.Don’t operate at extremely high temperature conditions

3.Keep the battery in a ventilated place.

4.Carry out maintenance check.


Take good care of the battery with preventive maintenance and your battery will have a longer life.
