Flat Plate Battery vs Tall Tubular Battery – Which is better?

Spread the love

You will see terms such as ‘Tall Tubular Battery’ and ‘Flat Plate Battery’ in our Inverter Battery Guide. These are just a few of the many battery types that are available today.

You also have sealed maintenance-free batteries. Let’s discuss the differences between flat and tall tube batteries.

Flat Plate Battery vs Tall Tubular Battery Which is better (Guide)

Flat Plate Batteries

These batteries can be referred to as first-generation batteries. These batteries are most often used by Indians. These batteries are the traditional lead-acid batteries one lead electrode and one lead dioxide. The electrode is made of sulfuric acid.

These batteries are lightweight and most cost-effective of all the batteries on the market. They require more maintenance than other batteries, which is a disadvantage.

These batteries need to be refilled with distilled water every three to six months, depending on how much you use them.

The battery can be damaged if it is not filled on time. Flat plate batteries are among the shortest-lasting of all types of batteries.

These batteries can also be used to charge other devices. Comparatively, unsafe they can emit toxic gases during charging and discharging, making them dangerous to use. These batteries should be placed in well-ventilated areas.

These drawbacks are the main reason why people choose to use tall tubular or SMF batteries to power inverters. There are not many models of inverters that can be used with flat-plate batteries.

Flat Plate Batteries: The Pros

  • Flat plate batteries have the greatest advantage: they are the most affordable.
  • Flat plate batteries are great for those who live in areas where power outages are not common.

Flat Plate Batteries: The Cons

  • Flat plate batteries need to be maintained and refilled with distilled water approximately every three to six months.
  • Flat plate batteries are not recommended for indoor use.
  • Flat plate batteries last for a shorter time than other types of batteries.
  • Flat plate batteries are not recommended for areas with extended power outages. They are not designed to deep discharge.
  • Flat plate batteries are more difficult to recharge than tubular batteries.

Tall Tubular Batteries

Tubular batteries are better versions of flat plate batteries. Tubular batteries are more expensive than flat plates batteries. Less maintenance they are. They last for up to five years.

The positive plate of the battery is protected by a tube and cloth. This also increases the battery’s efficiency.

The tall tubular battery component-wise is also a lead-acid one, but it has plenty of protection in the form of cloth and a protective coating.

The decay process takes longer than that of a flat-plate battery. This prolongs the battery’s life and reduces the need for distilled water toppings.
