T-H Marine Optima Battery Tray Holder for D27M and D31M – Rugged UV and Corrosion Resistant Marine Battery Tray with Poly Strap, Stainless Buckle, 8 Mounting Slots, 13" x 7"

Handy little addition to my camper, while I had it. Fit and secured my Optima batteries really well. Sturdy.

Great product, works perfectly with my (3) Optima D31M batteries. The strap and synch buckle are a great added feature and very secure and easy to use. I am using (3) NBH-31-SSC-OPT Trays, one for each of the 3 batteries mounted in my 2003 AlfaSeeYa 40FD Chassis Start System. I am happy with this product fit, function and ease of install. DYI Distributers and Amazon are very responsive and "Fast Shippers"

This battery case was perfect for the Optima BlueTop battery (D31M). I see that you can remove two additional "holders" and then use it for any regular 12volt Car battery. The reason I purchased these was to place three Optima batteries in a custom metal battery box for my Motorhome. I secured the T-H Battery trays using some small metal screws, and then blaced my Optima batteries inside. They are held down by the included belt and are now secure from bouncing around due to this product. Very well constructed and perfect for my use.

I tried to make my Group 31 Optima’s fit in a regular battery tray, using plastic wedges, wood, etc., but I finally buckled because I thought paying $24 bucks for a battery tray chunk of plastic was ridiculous. It still is ridiculous but the darn things fit em great and do the job. Typical TH marine pricing. Oh....and it’s just a simple battery tray with 2 inserts that fit inside. Cost to produce one is probably 7 bucks.

I was looking for a battery tray for my 31T and this product was the ticket. I installed it into a drag race car in the trunk. The fit of my 31T was perfect and I like the clean installed appearance of the tray. Nice product.

Purchased this item to secure my Optima D31 deep cycle for my toy hauler rv. Have a custom battery box. This tray designed especially for Optimas. And worked excellent! Comes with great instructions. And nylon secure strap, mounting screws. Extremely satisfied!

Very annoying, It is not very strong, 4 months later it cracked. Keeps the battery in place but very weak

This holder works perfect with my optima battery. You can remove the optima insert and just use it as a large tray also. I would recommend it to all.

Added a Optima D31M battery to my fishing boat to power and separate the "house" side of my electronics from my starting battery and needed a tray. This tray fits the Optima D31M battery perfectly. Getting the strap to cinch down properly took a couple of tries before I got the strap routing correct. Once correct, it secures the battery very well.
