Spec on Costco Batteries?

Wouldn't those numbers be different if the aH rating was different?

Haven't we come to the conclusion that Costco's typing is not to be trusted?

I'm pretty sure you have 208s. It's highly likely that the Interstates I quoted above are made by the same company. The evidence suggests you have 63# 208s.

Now...

For the same volume measurements of battery, if one is heavier, it probably has longer plates, i.e. less room at the bottom for sludge to build before shorting.

In the following link you will note that Trojan's T-125 is rated for 100 fewer cycles than the venerable legend, the T-105.

Also note this old thread.

Now if you really need the capacity, then shorter life might be inconsequential to you. AND... funny thing is... Yes... the T-105 may be able to tolerate more deep cycles. But... if you need that capacity... then you might actually be cycling the T-105s deeper than you would the T-125s. So much for the solace I was trying to toss your way.

Now on the T-105s... if they really have 225 Ah... at only 62#... I can't help but wonder if their plates aren't thinner than their Johnson Controls cousins.

So there! You got an extra pound of lead for a lot less money.

Enjoy
