Lithium or tubular: what really lasts in Owerri
Tubular batteries are cheaper on the day. Lithium batteries cost more and last much longer. Which is better depends on how often your power goes, and how deep you drain it.
How batteries wear out
Every time a battery is drained and recharged, it uses up one cycle. In Owerri, many homes cycle their batteries every single day.
A good tubular battery lasts about 1,200 cycles if you use only half of it each time. A lithium iron phosphate battery lasts about 6,000 cycles while using 90 percent of it.
The cost per year
A bank of four 220 Ah tubular batteries stores about 10 kWh but you should use only 5 of it. Replaced every three to four years, it costs about the same per year as a 10 kWh lithium battery that lasts ten or more.
Lithium also charges faster, needs no distilled water and does not give off gas, so it can live indoors.
Cheaper on the day is not cheaper by the year.
When tubular still makes sense
If your outages are rare and short, or the system is temporary, tubular is fine. They are also easier to replace one at a time.
Keep them ventilated, top them up with distilled water and never drain them flat.
What we recommend
For daily backup in Owerri, especially with solar, we recommend lithium. For an occasional backup in a rented flat, a small tubular bank can be the sensible choice.
In short
- Count cycles, not just price
- Lithium gives about five times the cycles
- Per year, lithium is usually cheaper
- Tubular still suits rare, short outages
