If you have found sealed, maintenance-free (SMF) deep cycle battery for inverters and power systems convenient to use, do note that there is a trade-off there, because the tubular battery option offers more robust performance and longer battery life.
Because SMF batteries don’t require maintenance (not really, because you still need to clean and tighten your battery terminals occasionally), they seem easier to use. But what if you have an assurance of markedly extended durability and better performance, at the price of just an occasional check of your battery and non-cumbersome periodic top-up? That assurance, in the case of the Luminous 220Ah/12V Inverlast Tall Tubular Battery, starts with an 18 months warranty. That implies a commitment that if your Luminous 220Ah/12V Inverlast tall tubular battery should fail anytime within 18 months, you get a replacement.
But they’re unlikely to fail, that’s the point. Tubular batteries have a more rugged construction that delivers much longer battery life and far superior performance. You get better deep discharge recovery and extended cycles of use. The Luminous 220Ah/12V Inverlast tall Tubular Battery maintains the Luminous tradition of superior product quality, meaning that you have solid assurance of quality performance. If you want an inverter battery that will deliver extended value, this top-performing tubular battery is where to place your money.`
What’s more, battery maintenance for the Luminous tubular battery has been made easy by design. With provided level indicators that extend above each battery cell, checking the battery is as simple as ABC – just a glace at the indicator tells if there is any need for a top-up. And if there is (which could be once in a quarter), you simply top with distilled water. That’s really all the trouble you need to take. The benefit? Many years of service from this rugged battery. Best of all, when the tubular battery eventually begins to lose strength (that is, the electrolyte gets weaker), you can revitalize it with a complete electrolyte change and boost charging.
