To be honest: Never heard about them but i bought another brand from pricemart several month ago and they were total crap.
Also 9,700 is very expensive for a unknown Battery ! You can get a "Trojan Rojo" for 10,700 RD$ at Almacenes Unidos and than you have by far the best Battery in the market. Why taking a change for saving only 1,000 RD$ per battery !?

Ihave a total of 6 inversors to maintain, 2 with 4 batteries and 4 with two bayyeries each. All except one have trojan T105 batteries. I just had the batteries in the one in my house give up. They are 5 years old so in my quest to get new ones I though I would explore the options. My MIL has Gel batteries with his inverter but they are expensive, though very reliable.

They are actually 10,595 in Jumbo at the moment. I know this as I had to buy four yesterday. Everyone said rojos are the way to go. You get a one year full guarantee, and the second year is proportional, so for example if you've had them for 18 months, they will give you 25% of their value if they break down (as you've had 18 months of the 24 months guarantee).

If it were me I'd have to try the gel batteries or maybe even better, lithium batteries? They last much longer than acid or gel batteries.

Here's one for 27K. (equal to 2 lead batteries)

Then you would need a new inverter/charger with the correct profile to charge those batteries as well.

AND:

12voltios 100ah equivalente a 2 baterías de plomo. PRECIO: 27,000
is 12V X 100ah = 1,200 kWh of power


Two Trojan T105's spec'd at 225 ah at 6 volts would be 2 X 225ah X 6V = 2,700 kWh of power.
If you use the 50% maximum discharge level recommended for lead-acid batteries so you don't kill them quickly you are closer at 1,350 kWh if you
can discharge those batteries to zero.
Which I guess is close enough.

But don't forget to get the new inverter/charger for those new batteries.

According to the vendor all you need to have is an inverter with a floating charger.

Floating at what voltage? Call me skeptical on the charge profile being OK for existing inverters.
Why not ask the guy who sells them and eliminate the dummy in the middle?

I will stick with Trojan batteries for he moment.

I would get rid of my battery/ inverter system completely if there were not so many Edenorte "maintenance" outages.

My Trace 235's are heading for their 5th anniversary and seem to be doing well (ever since I replaced the bad one)

I may go with one of those once mine buy the farm.

A long time ago in Sosua the first time I bought 8 red trojan batteries for my 5500watt inverter. The batteries have lasted more than 6 years. Then I bought 8 more at Sirena. I kept them for more than 6 years too. Then as the Trojan 105s became more expensive, I bought INTERSTATE made in the USA. I have had them for more than 5 years and they are still alive.

The last 8 batteries we bought were Interstate from Sirena. Pooped out in under 3 years

I am always carefull with batteries, i check them often and use normal 5 gallons drinking water treated with UV filter.
Probably OK, but there's a reason why battery water and filter water are two different things.
