If anything really worked, we would have heard about it.
These have been around for several years.
So they figured how to turn sulfate back into lead plate inside the battery? I don't think so.
The device employs the old mechanic trick of dead shorting a sulfated battery several times rapidly (a pulse) which supposedly knocks some sulfate off the plates. If a batter is really screwed with poor maintenance and no equalization, such action may actually work...temporarily. But even then the sulfate sinks to the bottom, building up a layer, until it comes in to contact with the bottom of the plates...and the battery totally dies with an internal short.
Proper maintenance and charging will extend battery life far beyond any such gimmick.
Your inverter should, at minimum, have an equalization charging phase.
I wouldn't spend RD$7k on one.
Decided to not spend (waste) money on the Megapulse device. After some more research I believe the advice above by windeguy/cobraboy sums it up regarding this device. Thanks.
I had a closer look at my inverter that were installed by the previous owner and found a switch for a manual equalization phase. I ran equalization with positive result, substantial increase when measuring with hydrometer.
The battery type setting on the inverter were also set to PbCa/Lead Calcium which I believe is not optimal since I have Deep Cycle lead acid. Changed that setting as well to slightly increase the charger bulk and float voltage.
Almost perfect now, but one cell in the bank of four 6V batteries has a hydrometer reading of 1225, all the others have 1265.
Guess that battery has gone slightly bad.
I decided to spend $36.50 on a battery monitor to better understand what amount of energy I consume during blackouts (quite frequent lately,edenorte), as well as remaining capacity. Also going to use the monitor to adjust the inverter charging setting to optimal values (I already have a voltmeter but lacks the ability to measure current)

Lesson learned, equalization cycle should be done to prevent sulphate build up. Very good information on the Trojan battery webpage,
Equalizing is an overcharge performed on flooded lead acid batteries after they have been fully charged.
It reverses the buildup of negative chemical effects like stratification, a condition where acid concentration is greater at the bottom of the battery than at the top. Equalizing also helps to remove sulfate crystals that might have built up on the plates. If left unchecked, this condition, called sulfation, will reduce the overall capacity of the battery.
Many experts recommend that batteries be equalized periodically, ranging anywhere from once a month to once or twice per year. However, Trojan only recommends equalizing when low or wide ranging specific gravity (>0.030) are detected after fully charging a battery.

1. Can I use battery additives?
Trojan Battery, along with other battery manufacturers, do not recommend that you add anything to your batteries other than distilled water. Extensive testing has shown that most of these additives do not work as advertised; in fact, some may do more harm than good. Be aware that adding anything other than water to your batteries will void the warranty.
2. Do you recommend the use of desulfators?
We don’t recommend the use of desulfators or any other external device, as they tend to do more harm than good. No external device or chemicals need to be added to our products – only distilled water.
3. Do you ever add acid to a battery?
Under normal operating conditions, you never need to add acid. Only distilled, deionized or approved water should be added to achieve the recommended levels mentioned above.
