They use the same glass mat technology as Kinetik. I'm thinking about putting three of these in the back of my car. What do you think?

Nominal Voltage........................................................ 12 volts (6 cells in series)

Nominal Capacity

20 hour rate (5.5A to 10.50 volts) ................................................... 110.0 A.H.

10 hour rate (10.3A to 10.50 volts) .................................................. 103.0 A.H.

5 hour rate (17.7A to 10.20 volts) .................................... 88.5 A.H.

1 hour rate (61.8A to 09.00 volts) ............................................... 61.8 A.H.

15 min rate (204A to 09.00 volts) ......................................................... 51.0 A.H.

Approximate Weight................................................................. 70.6 pounds (32.0 kg)

Energy Density (20 hour rate)................ 1.79 Watt-hours/cubic inch (109.2 Watt-hours/l)

That's one heavy bitch. What exact model are you looking at and also in comparison with Kinetik?

The powersonic PS-121100 vs. Kinetik 2000

And the PS-121400FR vs. Kinetik 2400

The way I'm reading this it seems to me like the Kinetik can deliver 3x the current for bursts than the PowerSonic can...

See...Kinetik doesn't give a good spec description for that.

At a direct short, BOTH batterys will deliver FARRRRRRRR more current than either rating. Kinetik doesn't specify how they arrive at that "amps" rating. Powersonic does. That is a plus for PowerSonic as far as I'm concerned.

To me this is the equivilent of a "max wattage" figure on amps. If they list a "max wattage" but don't tell you how they got that figure...I try to stay away.

Where can you get them?

I will get mine from a local battery specialty shop. I'm in northwest Arkansas.

Shipping would be pretty expensive, but still MUCH less than a Kinetik in the end.
