Batteries took a poop, going six volt.

Lower SG is for sure meant for a "storage" battery such as with a UPS back-up set and not for deep cycling action, so for an RVer you want the straight 105s not the REs.

Scroll down to the SG vs Application table

http://www.engineersedge.com/battery/specific_gravity_battery.htm

Some of the differences between regular 105's and 105RE's are in the following thread over on the Wind and Sun forum:

difference between a trojan t105 and t105re?

ISTR the REs are for shallow cycles as with solar and not so much for deep cycling as with golf cars and RVs off grid doing 50-90s, but I am unsure if I have that right. If correct then you want the straight 105s if you intend deep cycling.

Somebody here must know the correct story on that, or you could ask Trojan to be sure.

Thanks guys.

Here's the boxes I use for my 6 volts. Link

opnspaces - Thanks for the link. I'll be using the same built-in battery space/box that was built into the camper. I need to MacGyver the one I currently have i.e. cutting, fiber glassing etc.

I would like to keep and continue using the battery pullout... we'll see what happens.

Wayne - Thanks

mkirsch - The "RE" has thicker and slightly larger plates.


"Trojan's proprietary Maxguard Advanced Design Separator and exclusive Alpha Plus paste formulation team up to increase battery life, extend run time and decrease maintenance. The RE Series is an advanced generation of renewable energy batteries featuring the following key advantages not available from any other renewable energy product * DuraGrid technology provides a 8-year design life and excellent charge efficiency *Maxguard XL Advanced Design Separator is 30% thicker and stronger, resists stratification, extends life and lowers overall maintenance costs * Alpha Plus paste formulation promotes longer life and optimum performance * Polyon - Trojan's ultra-rugged case design stands up to the harshest of environments."
The Trojan rep said the lead plates we're thicker. (an extra $23 ea. for a total of $148.00 per battery.

They're both the same battery except for terminals. I guess it's up to the type of terminal you prefer.

Frankly, after growing up on a farm with an electric feed cart that used the stud terminals like the T105, and now dealing with a golf cart that has the same %$#@ terminals, I think I'd give the T105RE a try. At least you could use stainless hardware throughout.
