Did you buy the inverter to get a peaceful sleep during power outages? The sadness lies in the fact that the device never lets you enjoy that peace of mind. The problem never lies with the inverter, but rather in the choice of battery you make when living in a country like Nigeria, as power outages are a common phenomenon in a country like Nigeria.
Generally, there are different types of batteries with varying suitability. Choosing the best option that fits your requirements can be overwhelming. Apart from relying on the seller, you have the perfect weapon of knowledge to make a solid decision. As a result, to arm you with the same, we offer detailed insights, and indeed, a comparison exists between a tubular battery vs flat battery. Through this blog, scroll down to learn about these two types of batteries and find the opportunity to select from the best of both worlds.
Understanding Inverter Batteries
Before proceeding to the comparison between tubular and flat batteries, let us first try to understand the inverter battery. Thus, a flat tubular battery in an inverter is a critical component that stores power to provide it during electricity outages in Nigeria. Therefore, the used-up power can be quickly replenished when the main power is restored. It is the tall, tubular battery from Star Plus Battery that stores power according to the rated capacity, which primarily determines the amount of time the inverter can sustain during power cuts.
There exist different types of batteries, including lead-acid batteries. The latter is categorised as follows.
-
Flat plate lead-acid Batteries
The Flat plate lead acid batteries are mainly reliable and affordable by nature. They primarily consist of plates of lead and lead dioxide that are present in sulfuric acid.
-
Tubular batteries
These are another type of lead battery which comprises thicker plates. They indeed exhibit higher efficiency and durability. Making it suitable for heavy-duty applications.
-
Valve Regulated Lead Acid (VRLA) batteries
These are mostly known as maintenance-free batteries. They are primarily sealed, don’t require maintenance, and are safe to use.
Understanding Flat Plate Batteries
It is the name of these batteries that justifies their design. This flat tubular battery features flat plate electrodes at both the positive and negative terminals. These are ideally suited for areas in Nigeria that experience frequent power outages and small homes.
They are affordable and come with a lifespan of one to three years. These tubular battery vs flat battery isn’t designed to meet the needs of heavy-duty equipment. They indeed exhibit rapid charging due to the perfect battery design, metal composition, and structure. Flat batteries mainly offer a sleek and modern appearance, as they consume less space.
Applications of Flat Batteries
In general, the flat batteries from Star Plus Battery are well-suited for use in the following locations.
- Typically, it powers up residential and small-scale commercial areas for a short duration.
- To provide power for portable devices that require battery power
- Primarily for powering the engine and providing auxiliary power for automotive and marine equipment.
- To power alarm systems and emergency lighting during a power outage.
Understanding Tubular Batteries
According to experts from Star Plus Battery, these types of batteries are designed in such a way that the positive electrodes are tubular in structure, while the negative electrodes are flat plate-type. They are capable of meeting the needs of long and less frequent power cuts. As a result, they are available at a comparatively higher cost range. These are capable of serving the functions for at least four to six years. Primarily, they meet the power requirements of heavy-duty devices and provide extended backup times. These require low maintenance and are inherently space-efficient.
Applications of Tubular Batteries
Normally, tubular batteries are well-suited for use in the following locations as well.
- However, to run equipment like computers, fans, TVs, lights, and such appliances at home and in offices.
- To continuously keep running the power plants.
- To power up the solar power systems to provide power at night or on non-sunny days
- Even for usage in telecommunication networks.

Difference Between Tubular and Flat Battery
Some of the differences between a tubular battery and a flat plate battery are as follows.
-
Charge cycles
A tubular battery has 800 to 1400 cycles at a similar depth of discharge. A flat battery has 50 to 1000 cycles at 80% depth of discharge.
-
Float current
A tubular battery has a low self-discharge rate. At the same time, a flat battery has a comparatively higher self-discharge rate.
-
Thermal management
A tubular battery is inherently thermally efficient. At the same time, flat battery is comparatively less thermally efficient.
-
Cost
A tubular battery has higher cost. At the same time, flat batteries are budget-friendly in nature.
-
Use
A tubular battery is suited for prolonged, less frequent power outages. A flat battery is suited for frequent and short-duration power outages.
-
Charging time
The tubular battery has a longer life with a higher capacity. Flat battery has shorter charging times and are of lower capacity.
-
Lifespan
A tubular battery has a longer lifespan. At the same time, flat battery has shorter lifespan.
-
Heavy load performance
The tubular battery has excellent load performance. A flat battery exhibits poor performance under heavy loads.
-
Maintenance
A tubular battery requires less maintenance, and you get more from a flat battery.
-
Electrical resistance
A tubular battery has less resistance to electricity. A flat battery has comparatively higher electrical resistance.
Concluding Thought
Indeed, among the lead-acid batteries for your inverter, the challenge mainly lies in choosing between a flat battery and a tubular battery. Most flat batteries are economical and suitable for areas with frequent and short power outages.
These tubular batteries are mainly suited for contrasting environments. However, you certainly have the option to choose the benefit of both. At Star Plus Battery, our batteries are engineered to last longer with fast backup. Tubular and flat plate technologies mostly create these at affordable prices.
