Battery Box for single Trojan T-1275

The Noco HM327BKS (Group 27) is also a close fit (13.2 x 7.2 x 10.1) but still short. The NOCO Group 24-31 box is even shorter.

I love the Trojan 12V T-1275 Battery idea and its 150AH capacity... Alot of users on here for that battery. The charging voltages are slightly higher that the so called industry standard... I was thinking of using two of those those in my upcoming battery box build but looks like I am going to settle for the two groups of two Trojan 6V T105s in series. This will give me around 450Ahs of capacity...

Check with the TORKLIFT line of battery boxes. These have the slide off lid which is great when installed in tight places. They also have a model that has a small solar panel on it which may help help trickle charge your battery when in high Sun...

You can find all sizes of plastic storage boxes at WALMART... I have used the ACTION PACKER Containers for a couple of batteries at one time...

Another source is Truck Bed Tool Boxes from the auto parts places... They have a couple that are wedge shape to fit on top of the trailer tongue area... These come in all kinds of different dimensions... Order from AMAZON

This is just me but I would not like the idea of just having one battery. I know exactly what would happen to me when camping off-grid haha... I gotta have a good plan B for just about everything when it comes to camping... Being a RV traveler I guess is not so demanding for Plan Bs... Just call the auto club as they say on TV...

A NOCO HM426 would hold a T-1275 provided you have sufficient space to accommodate the box's external dimensions.

Thanks for the all the info guys! For now I'm going with a single heavy duty storage container from Walmart. I've got some solar panels that I've owned for years that I need to install, purchase a charge controller, and then I'll probably buy another 1275 and re-visit the container issue.

I think you are reading the spec sheet wrong ! T1275 is 280 minutes @25A, so 2 would be 560 minutes. T105 is 447 minutes @25A. The other quick way is simply compare weights (seeing as the amount of lead in a flooded lead acid is the most important thing). 85# vs 62#

There will be a lot of extra space inside to the battery to rattle around.

The 280 figure is Reserve Capacity. The Amp Hour rating is 150 AH.

Think outside the box :W - just sit the battery in a tray mounted in the box and it won't go anywhere. :R

I have a Trojan T-1275 plus with the fill caps in a row, not angled.
The Moeller Injection-Molded Marine Battery Box (13.44" x 7.75" x 10.5") works out perfectly and even has enough room at the top.
