Suppose you’ve just invested in a tubular battery for your home or solar setup. The power cuts no longer bother you, the inverter hums smoothly, and life feels uninterrupted.
Fast forward one year… and suddenly, backup time drops, water levels dip fast, and performance feels sluggish. Sounds familiar?
The truth is — tubular batteries are long-lasting, but they need care. Just like you service your car to keep it running for years, a battery also needs regular attention to perform efficiently and live its full lifespan.
In this complete guide by Myoko India Private Limited, we’ll walk you through simple, practical, and tested tips to maintain your tubular battery for years of reliable power — whether you’re using it for home, office, or solar applications.
Understanding Tubular Batteries
Before jumping into maintenance tips, let’s quickly understand what makes a tubular battery different.
A tubular battery is a type of lead-acid battery designed with thicker positive plates in a tube-like structure. This design gives it higher efficiency, deep cycle life, and longer durability compared to normal flat-plate batteries.
That’s why they’re commonly used in:
Home inverters
Solar energy systems
Commercial backup systems
Rural and industrial applications
But despite their strength, tubular batteries demand routine care — especially in hot and humid climates like India, Africa, or Southeast Asia.
So, let’s dive into how you can make your battery perform like new even after years of use.
1. Regularly Check the Water Level (Every 3 Months)
Let’s start with the simplest yet most powerful tip: check the water level.
Tubular batteries use electrolyte (a mix of water and acid) to store and release power. Over time, the water level drops due to evaporation and charging cycles. If you don’t top it up regularly, the plates get exposed, causing permanent damage.
Here’s what you should do:
Check electrolyte levels every 2–3 months.
Use only distilled water — never tap or RO water.
Maintain water between the minimum and maximum mark on each cell.
Pro tip: Set a calendar reminder every quarter — it only takes 10 minutes but can add 2 extra years to your battery life.
2. Keep the Battery Clean and Dust-Free
Dust, moisture, and rust are silent enemies of your tubular battery. They cause slow discharge, corrosion, and even short-circuit risks.
To prevent this:
Wipe the battery surface with a dry cotton cloth every 15–20 days.
Keep the terminals clean — apply petroleum jelly or anti-corrosion grease on terminals after cleaning.
Make sure your battery room is well-ventilated and cool.
Remember: batteries breathe too! Proper air circulation helps maintain temperature and performance.
3. Never Let Your Battery Sit Idle for Long
Many users think, “If there’s no power cut, my battery stays new.”
But in reality, inactive batteries age faster.
A tubular battery loves being used — regular charge and discharge keep it healthy.
If you leave it unused for months, the electrolyte starts stratifying (acid settles at the bottom), reducing its efficiency.
Maintenance Tip:
If you don’t have power cuts, try to discharge the battery manually once every 45 days. Run some appliances through the inverter to keep the battery active.
4. Avoid Deep Discharge — Don’t Drain It Fully
One of the biggest enemies of tubular battery health is deep discharge.
If you keep running your inverter until the battery completely dies, you’re silently killing its plates. Deep discharge stresses the internal chemistry and shortens the lifespan drastically.
Ideal practice:
Never let your battery go below 20–25% charge.
Keep an eye on your inverter indicator — when it signals low battery, switch off high-load appliances.
Use energy-efficient lights and fans to reduce load.
Over time, this simple habit can extend your battery life by 30–40%.
5. Use a Quality Charger and Inverter
The battery may be the heart of your backup system, but your inverter or charger is its brain.
If the charging current is too high or too low, it damages the plates and reduces efficiency.
That’s why investing in a quality inverter/charger is just as important as buying a good battery.
Quick checklist for your inverter:
Compatible voltage & charging settings
Trickle charge mode support
Automatic voltage regulation (AVR)
Proper ventilation around the unit
Bonus tip: During power cuts, avoid switching on heavy appliances like refrigerators, irons, or water pumps — it strains both your inverter and battery.
6. Recharge the Battery Immediately After Discharge
Imagine your phone staying dead for days — it wouldn’t feel good, right?
Similarly, don’t let your tubular battery stay discharged for long.
Lead-acid batteries develop sulfation — a condition where lead sulfate crystals harden on plates if left discharged. This permanently reduces the battery’s ability to store energy.
Golden rule:
Recharge the battery as soon as possible after a power outage or usage. Even if the inverter doesn’t auto-charge, plug it in manually.
7. Maintain Proper Installation Space
Most battery issues begin with improper installation.
Your tubular battery should always be installed in a place that’s:
Well-ventilated — heat kills performance.
Away from sunlight and moisture.
Raised slightly above floor level (avoid direct floor contact).
Easy to access for maintenance checks.
For solar tubular batteries, keep the room temperature ideally between 25°C to 35°C for optimal performance.
8. Equalize Charging (Advanced Tip for Solar Systems)
If you use solar tubular batteries, you must have heard about equalization charge — an essential maintenance feature.
Equalization is a controlled overcharge process that removes stratification and sulfation, keeping all battery cells balanced.
How to do it:
Most modern solar charge controllers or inverters have an equalization mode. Run it once every 3–6 months under supervision. It revives battery health and improves overall efficiency.
(If you’re not sure how to perform it, contact your installer or Myoko India service team.)
9. Protect Your Battery from Overheating
Tubular batteries are designed for resilience, but high temperatures accelerate water loss and chemical degradation.
Tips to prevent overheating:
Keep the battery in a shaded, ventilated area.
Avoid placing it near heat sources or direct sunlight.
Check inverter fan function regularly.
If you live in a hot region, inspect electrolyte levels more frequently.
10. Periodically Test Battery Voltage and Specific Gravity
To ensure your tubular battery is performing optimally, test:
Battery voltage using a voltmeter
Electrolyte specific gravity using a hydrometer
This helps you know if your battery is charging/discharging properly.
If readings are off-balance, it could indicate:
Overcharging
Undercharging
Cell imbalance
Water shortage
Your local battery technician or Myoko service partner can help check and rebalance the cells safely.
Real-Life Story — How a Small Habit Doubled a Battery’s Life
One of our distributors from Kenya shared an inspiring story.
A rural school installed Myoko solar tubular batteries in 2019. Their technician trained the staff to:
Check water levels every 2 months
Wipe terminals regularly
Use energy-efficient lights during backup
Five years later, those same batteries are still going strong — delivering 80% of their original backup time.
That’s the magic of small, consistent care!
Bonus Section: Maintenance Myths You Should Stop Believing
❌ Myth 1: “Adding acid improves performance.”
👉 Truth: Never add acid! Only distilled water should be added. Extra acid harms plates.
❌ Myth 2: “New batteries don’t need maintenance.”
👉 Truth: Even new batteries lose water and gather dust. Early care prevents long-term issues.
❌ Myth 3: “Running battery till empty helps it calibrate.”
👉 Truth: Deep discharge shortens life. Always recharge before it drains fully.
