What does FLA stand for?

Why are flooded batteries so called?

Flooded batteries are so called because they contain an excess of electrolytic fluid so that the plates are completely submerged.

As the batteries discharge, the chemical reaction produces oxygen and hydrogen which are released from the batteries. As a result, the electrolytic fluid starts reducing. But it should never be allowed to fall below the top part of the plates, thus exposing them. If that happens, the plates will get damaged and their life will reduce considerably. That is why they have to be periodically filled with distilled water to maintain the electrolytic fluid level above the top part of the plates.

What are the advantages of flooded batteries?

Advantages of flooded batteries are:

  • Long proven history of use
  • High discharge rate capability
  • Perform better in hot climates
  • Perform better than VRLA batteries when regularly in a partial state of discharge
  • Lowest price of all the battery types

What are the disadvantages of flooded batteries?

Disadvantages of flooded batteries are:

  • Have a higher self-discharge rate as compared to VRLA batteries
  • Need to be periodically refilled with distilled water
  • Can only be used in an upright position
  • Produce gas while charging and so require ventilation
  • Cannot be kept in the vicinity of any electrical equipment or any inflammable material
  • May emit acid spray if overcharged abusively
  • Cannot be shipped by air

Do I have to periodically add distilled water to flooded batteries?

Yes, you have to periodically add distilled water to flooded batteries. The level of the electrolytic fluid in the battery must be maintained between the min and max levels at all times to ensure that the battery works properly and doesn’t become dry. If the battery becomes dry, its life reduces drastically.

How often do I have to periodically add distilled water to flooded batteries?

Typically, you will have to add distilled water to flooded batteries once in 6 months, if the battery and its charger are in good condition. But it is better to check the electrolytic fluid levels once a month. If the level goes down earlier than 6 months, it means that there is some problem with the battery and/or its charger and needs to be looked into.

What does “top up of flooded batteries” mean?

To “top up” means to add distilled water to flooded batteries. They are one and the same thing.

Do flooded batteries give more current as compared to maintenance free batteries?

 

Yes. As a general rule, flooded batteries give more current compared to maintenance free batteries. So for applications that need high currents, flooded batteries are more suitable. However, they will need periodic maintenance.

But please check the technical specifications documents of the batteries that you are planning to use for the exact details.

Do flooded batteries perform better than maintenance free batteries in hot climates?

 

Yes. As a general rule, flooded batteries perform better than maintenance free batteries in hot climates. But please check the technical specifications documents of the batteries that you are planning to use for the exact details.

Are flooded batteries cheaper compared to maintenance free batteries?

Yes, flooded batteries are cheaper compared to maintenance free batteries, and significantly so in many cases. And that is the main reason why they are more popular in India which is a very price-sensitive market.

Do flooded batteries have a higher self-discharge rate as compared to maintenance free batteries?

 

Yes. As a general rule, flooded batteries do have a higher self-discharge rate as compared to maintenance free batteries. What that means is that you will be able to store them for lesser amount of time compared to maintenance free batteries, before they will need to be charged.

Can flooded batteries be operated only in an upright position?

Yes, since flooded batteries are “flooded” with electrolytic fluid, they need to be operated in an upright position.

Do flooded batteries produce gas while charging?

Yes, flooded batteries produce gas while charging. That is why need to be kept in a place which is properly ventilated.

Can flooded batteries be kept in the vicinity of any electrical equipment or any inflammable material?

No. Since flooded batteries produce gas while charging, they cannot be kept in the vicinity of any electrical equipment or any inflammable material.

Do flooded batteries emit acid spray?

Yes, flooded batteries can emit acid spray if overcharged abusively. Please follow the safety instructions while handling flooded batteries.

Can flooded batteries be shipped by air?

No, flooded batteries cannot be shipped by air.

Do you have flooded lead acid batteries?

Yes, we have flooded lead acid batteries.

What different types of flooded lead acid batteries do you have?

Yes, we have flooded lead acid batteries. The range is called Tubular Eco. Please visit its web page for detailed technical specifications.
