Choosing between a tubular (wet cell) non-free maintenance battery and a lithium battery depends on several factors and the specific application you have in mind. Both types of batteries are strong and effective in storing energy for inverter and solar applications, their difference lies in their makeup.
Tubular solar batteries use lead-acid chemistry and are capable of deep discharge (discharging and recharging repeatedly) and are durable. Batteries from reputable brands can last for many years. However, tubular batteries, more than conventional dry cell batteries, take up space and might be a source of concern where room is limited.
Lithium batteries are known for their high energy density. It can store a large amount of energy in a relatively small package, hence taking up very little space.
Just like tubular batteries, lithium batteries too have a long lifespan and a high number of charge-discharge cycles. However, care must be taken to buy from a reputable brand.
In addition, lithium batteries charge at a faster rate and are very suitable in Nigeria where power supply is erratic. It also has a high charge and discharge efficiency, number of charge cycles, and a better depth of discharge (DoD).
A major advantage lithium batteries have over tubular or wet cell batteries is that lithium batteries are maintenance-free, while tubular batteries require the recommended demineralized water to be above the recommended level as seen on the gauge. T
Son’t freight, this is not something you have to check or do every now and then. Depending on the battery’s usage, it can go for several months before it will require a topping of distilled water.
The distilled water is an inexpensive liquid electrolyte solution of sulfuric acid and water which ensures the battery’s usage and performance.
Though lithium batteries don’t need to worry about this, they are much costlier than tubular batteries.
So if you have that extra space and do not care about some little rust and spills, then tubular batteries can win you over. But if you are space-conscious and want a fancy-looking and energy-packed single power bank, say hello lithium!
