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 occassionally), 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 occassional 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 a 12 months warranty.
That implies a commitment that if your Luminous 220Ah/12V Inverlast tall
tubular battery should fail anytime within 12 months, you get a replacement.

But
they're unlikely to fail, that's the point. Tubular batteries have a more
rugged contruction 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 you 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 revitalise it with a complete
electrolyte change and boost charging.

LUMINOUS INVERLAST TUBULAR BATTERY
220AH/12V PERFORMANCE FEATURES

So,
what really makes the tubular battery tick? Here are key features of the
Luminous Inverlast Tall Tubular Battery that give it the punch it has:

§  Unique
patented alloy composition

§  Void
free, uniform grain structure

§  Extremely
high purity, corrosion-resistant proprietary spine alloy

§  Proprietary
spine design ensures uniform distribution of positive active material

§  Extra-strong,
flexible oxidation-resistant gauntlet for higher performance and extremely long
life.

§  Highly
puncture-resistant DARAMIC-USA separator

§  Equally
spread positive active material

§  Better
and quick charge acceptance

§  Designed
to have a life of over 1250 cycles at 80% Depth of Discharge (DOD)

§  Extremely
high purity, corrosion-resistant proprietery spine alloy composition ensures
longer battery service life.

§  Manufacture
of spines using HADI high pressure casting machine, helps maintain void free
and uniform grain structure.

§  Tubular
plate construction ensures uniform distribution of positive active material for
extremely long life and superior performance.

§  Highly
puncture-resistant polyethylene separator minimizes the possibility of internal
short circuits.

§  Balanced
plate design for improved charge acceptance & excellent deep discharge
recovery.

§  Inter
partition connection ensures the lowest internal resistance and excellent
charge acceptance.

§  Sleek
appearance in sealed plastic housing with minimum footprint.

§  Level
indicators for easy maintenance

It's
all for the user's benefit. If what you want is better performance, even at the
cost of occassional attention to the battery that isn't too demanding, place
your bet with the tubular battery options. Tubular batteries offer far better
long term value.
