The Trojan T-105 has a 5 hour rate of 185 A/H, 225 A/H over the 20 amp
rate. The T125 and T-145 have higher capacities in the same size case. The
T-145 is 215-5 hour and 260 for 20.

Subject: CDN Tire: Two 6 volt vs One 12 volt battery question

Having read the post regarding Canadian Tire's battery sale, CDN Tire has
2 batteries that seem to
be what I want/need:

If your browser breaks up those URLs, The specs are:

6 volt:  $85 CDN - Features

    * Deep-cycle 6 V battery can be used with solar panels as a source for
stored energy when used

       in conjunction with inverters
    * 390 minutes of reserve capacity (at 25 amps)
    * 150 Amp Hours (at 6 hours)
    * Also fits golf cart applications
    * 6-month manufacturer's warranty
    * 6-month free replacement

12 Volt:;  $213 CDN Features

    * Renewable energy deep cycle battery
    * 12V sealed AGM (Absorbed Glass Mat) deep cycle lead acid battery
    * Designed to be used with Xantrex PowerHub 1800 (11-1877) or as part
of any battery bank for
a
          renewable energy system
    * 100 ah at 100 hour rate

I know VERY little about electricity.  but I do know that 2, 6 volts can =
12 volts.

So which is "better"?   My intended application/use is:

Battery under rear seat (so no space limitations), to power all stock
interior lights and my
lap-top through an inverter,  but NOT the Dometic fridge; I have a top
loading Waeco compressor
type fridge that draws, on average (at 70 Deg F) 1 amp per hour.  I figure
that 3 to 4 days of NOT
running the van (to charge the batteries) will be about all I'll need.

I also plan to maybe add a solar panel to the top of my van, maybe a 2 or
3 amp panel.

I also have a SurePower 1315 and I called them and they said their unit
would not care if it sees
One 12 volt or Two 6-volt batteries.
Cost is really NOT a factor, (but 2x$85 = $170, or $213) I want the best,
more reliable, and
longest running set-up.

So which is "better"....................  I fear the answer will be "There
are trade-offs...."
