Tubular battery vs Lead acid battery

What is the difference between tubular battery and lead acid battery is the first question pops up in your mind when you plan to purchase the inverter battery online or offline. In fact, the same question is asked in another way like the difference between tubular battery and flat plate battery. Let us go to in details. Try our Inverter selector to choose right inverter by answering simple questions without reading any buying guide.

What exactly is the lead acid battery?

There so much confusion in the naming of inverter batteries lets clarify it first. All the recharge inverter batteries are the lead acid battery. Lead acid batteries contain two electrodes dipped in the electrolyte solution. The electrodes are Lead and Lead dioxide, hence the name lead acid battery. The sulfuric acid is used as the electrolyte. When these two electrodes dipped in sulfuric acid, causes the chemical reactions which indeed generates DC current. The best part is chemical reactions are reversible making it rechargeable.


Types of Lead acid batteries

All the models, types, manufacturer build the lead acid batteries in the same way. There are two types of lead acid batteries

  1. Flat plate batteries
  2. Tubular batteries
Surprised, the tubular battery is a type of lead acid battery. But many of us think that the flat plate is another name for lead acid battery, which is wrong. In fact when people refer tubular battery vs lead acid battery is like comparing mango with fruit. What they mean actually is tubular battery vs flat plate battery. There are minor differences in the flat plate and tubular batteries, but these minor differences make a big impact on the lifespan of battery, efficiency, weight and price.


How tubular and flat plate are technically different?

Well, the simple reason changes in positive plate. The positive plate is critical and decays as time passes. In tubular battery positive plate is replaced with a tube made of cloth and coated well, hence the name tubular. Because of the tube, the decay process is slow and hence increases the lifespan of the battery. For the same reason, the maintenance and the number of distilled water toppings are also less. The below table summarises the differences structurally.


Feature Flat plate battery Tubular battery
Electrode type Positive and negative plates Positive tube and negative plate
Battery Life Low (~ 3 Yrs) High (~ 5 Yrs)
Efficiency Has low efficiency, there is much wastage of current. Has high efficiency, there is very less wastage of curren. Will have lesser electricity bills long term.
Maintenance High Medium
Water toppings High Medium
Safety Low Low
Releases harmful gases Yes Yes
Ventilation requirement Yes Yes
Weight Low High
Price Rs. 9,000 to Rs. 15,000 Rs. 9,000 to Rs. 25,000.
