Trojan T-145 vs US Battery US145xc

[Triguy]

Looking at these two 6v batteries.

Is there any reason to pay extra for the Trojan for only 9amps?

sorry for the formatting hack job ...

Cost $200 $153


5 Hour Rate 215 213
20 Hour Rate 260 251

Min @ 25 Amps 530 562
Min @ 75 Amps 145 154

Width 7-1/8” 7-1/8"
Height 11-1/2" 11-7/8"

Hi Scott=]

Idk what all that means so I can't comment.

J/w about the reason you want 2 6v batteries VS 1 12v battery?
I'm sure there are pros and cons with each set-up......?

Why 2 x 6V ? More amp-hour available.

If one does lots of boondocking or dry camping, (no shore power) typically 2 deep cycle 6V will give much more mojo than 1 12V or 2 12V for that matter.

To the OP, taken care of well, I suspect the US145 would do well at a decent price.

Hi Kim,
Denis nailed it. More reserve capacity and longer life.

6v golf cart batteries are true deep cycle batteries and will last a lot longer than most common 12v batteries in a trailer and they have a higher capacity than group 24 and 27 batteries.

A pair of group 24 12v batteries in parallel only provides 140-170 Amp hours of capacity, whereas a pair of golf cart batteries in series provides 220-260 Amp hours.

The cons are the extra upfront cost and greater weight of 6v batteries.

Thanks for the suggestion, Denis. Its hard to pull the trigger on the Trojan's. Not sure they are worth the extra money just going by the specs.

It's more than just about specs. It's about how well the battery takes a charge, how long it lasts, etc. These are things that can't be put into specs. We bought Trojan but I expect to get at least 8 years out of it. We also use a Battery Minder which does a wonderful job of maintaining a full charge, de-sulphates, etc. My 2003 Yamaha still has its original battery and is working fine because of the Battery Minder. 8 years on a motorcycle battery and still tests fine. So, are you in it for the long haul? That's the real question I think. Best of luck on your decision.

[Triguy]

Thanks Bob. Still torn. i just can't find any reason why the Trojan would last longer or charge better to justify the cost other than the Trojan's are slightly heavier so maybe beefier plates.

The real problem is I am a past Trojan battery user and I know its a good battery. But that was from a few years ago when they were much less expensive. They seem to have jumped up a bit more than the comps.

[Labzy]

Hmmmm, and so I can guess that there is also extra cost involved in installing (wiring) them, and also the issue of finding room for 2 batteries up front.

You hit the nail on the head. AH capacity is a function of how thick the plates are. The higher the AH the thicker the plates. Thin plates equal high current flow but few hours (maybe even not one!) - good for starting engines; while thick plates equal lower current flow (like 20-25 amps) for a very long time - what you want in a deep cycle house battery.

Have you checked the price of lead? As any bullet caster or fishing weight caster will tell you; lead is up 800% in the last 10 years.

[Triguy]

Yea - lead ... and gas ... and food ... Ouch

Thankfully not all by 800%, though.
