In many parts of India, especially during peak summer or monsoon months, power cuts are still a common issue. That’s why most households and small businesses rely heavily on inverter systems. But what happens when your inverter battery — the very heart of your backup system — starts draining faster than it should?
At Sarex, a trusted tubular battery supplier in UP, we understand how frustrating this issue can be. In this blog, we’ll break down the possible reasons why your tubular inverter battery is draining too fast and how to fix or prevent it.
Common Reasons Why Your Inverter Battery Drains Quickly
1. Overloading the Inverter
One of the most common causes of fast battery drainage is connecting more appliances than your inverter is designed to handle. Running heavy-duty devices like refrigerators, washing machines, or air conditioners can put an unnecessary load on the battery, draining it much faster.
Tip: Always check your inverter’s VA rating and connect only essential appliances.
2. Low Battery Capacity
If the battery’s AH (Ampere-Hour) rating is not suited to your power needs, it will naturally drain quicker. A low-capacity battery may be unable to sustain your usage during longer power outages.
Solution: Upgrade to a higher capacity tubular battery from Sarex, which is designed for deep discharging and long backup.
3. Battery Age and Condition
All batteries degrade over time. If your battery is older than 3–5 years, chances are it’s losing its charge-holding capacity.
What to do: Have the battery tested by a technician. If the voltage or charge retention is below optimal levels, consider replacing it with a new Sarex tubular battery.
4. Improper Charging or Defective Inverter
A faulty inverter may overcharge or undercharge your battery, leading to poor performance. Similarly, irregular voltage from the grid can affect battery charging cycles.
Fix: Get your inverter checked for charging voltage consistency. Sarex batteries work best when paired with inverters calibrated to match their specs.
5. Poor Maintenance
Corroded terminals, loose connections, or dry cells in unsealed batteries can reduce efficiency.
Maintenance Tip:
Clean terminals regularly.
Top up water levels (if your battery is not maintenance-free).
Keep the battery in a well-ventilated and dry location.
Avoid deep discharges.
