Detailed Review
The listing states a dual tray for 2 Group 27 deep-cycle marine batteries, with a poly strap and a quick-release buckle, tough, durable build quality and NMMA requirements met. The bullets give the tray size as 14-1/8 by 12-3/8 by 1-1/8 inches, while the spec table gives package dimensions of 15.91 by 13.62 by 1.73 inches, so the bullet size is the tray size to measure against. The listing states no warranty term, giving only a warranty information web address in the spec table.
Who it's for: boat owners who need a dual tray for 2 Group 27 deep-cycle marine batteries with a strap hold-down. Who should skip it: owners who need a stated warranty term or a tray for a different battery group.

The listing states a passenger side battery tray for Cadillac Escalade, Chevrolet Silverado, Suburban, Tahoe and Avalanche, and GMC Sierra and Yukon, with a powder coat finish and a base clamp and tray set.

The listing states no warranty term and no tray dimensions, giving only a weight of 3.8 pounds and alloy steel as the material.
Who it's for: owners of the listed pickups and SUVs who need a replacement passenger side tray. Who should skip it: owners who need a dual tray, a stated battery group fit or a stated warranty term.

How we scored them
The Solar Score weighs performance, build, value, safety and warranty. For a battery tray, safety means stated standards and a hold-down that keeps the battery in place: ABYC, USCG and NMMA statements in this group, plus the buckles, straps and crossbar each listing states. Only the Attwood tray states a warranty term, at 90 days, and the other trays state no term. Value reflects how completely the listing states the fit, the hold-down and the standard, not a price, since no prices appear in this article. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Seachoice Dual Tray | 9.6 | 32 | 21 | 21 | 7 | 0 |
| T-H Marine Dual Holder | 9.6 | 30 | 21 | 20 | 7 | 0 |
| Attwood Group 27 Tray | 9.5 | 23 | 20 | 20 | 7 | 1 |
| T-H Marine 31 Tray | 9.5 | 24 | 22 | 20 | 7 | 0 |
| ARONOVA Battery Tray | 9.3 | 23 | 20 | 20 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
How to choose the best dual battery tray
Start from the battery group
Group size decides fit before anything else. The dual holders here fit Group 27 batteries, the Attwood tray fits a Group 27 battery, and the T-H Marine 31 tray fits 31 Series batteries. Check the group marked on the battery before choosing a tray, and see our battery tray dual guides for the battery side. A tray built for a given group will not suit a battery from another group, so the group check comes before colour or brand loyalty. The ARONOVA tray is the exception in this group, with fit stated by vehicle rather than by battery group, so check the fitment list before choosing it.
Compare hold-downs, not just the tray
A tray holds its value only if the battery stays put when the boat moves. The Attwood tray uses an adjustable-height crossbar with 2 retaining bolts, the dual holders use a quick-release buckle or a poly strap with a quick-release buckle, and the T-H Marine 31 tray uses a stainless steel buckle. For the battery side, see our deep-cycle RV battery guides. Check the hold-down on arrival: the crossbar should sit flat across the battery, the buckle should close without forcing, and the strap should sit across the top of the battery without slipping to one side. A buckle that releases quickly saves fumbling in a tight locker when the battery needs attention.
Check the stated standards
Standards state what the tray was built to meet. The Attwood tray meets ABYC standard E-10 and U.S. Coast Guard requirements, the T-H Marine dual holder states USCG and ABYC compliance, and the Seachoice and T-H Marine 31 trays state NMMA requirements or certification. The table below lines up each tray with its stated standard, so the standard check takes a glance rather than a search through every listing.
| Tray | Stated standard | Hold-down |
|---|---|---|
| Seachoice Dual Tray | Meets NMMA requirements | Poly strap, quick-release buckle |
| T-H Marine Dual Holder | USCG and ABYC compliant | Quick-release buckle |
| Attwood Group 27 Tray | ABYC E-10, U.S. Coast Guard requirements | Adjustable crossbar, 2 bolts |
| T-H Marine 31 Tray | NMMA certified | Stainless steel buckle |
| ARONOVA Battery Tray | Not stated | Base clamp |
Measure the space before buying
Tray dimensions decide whether the tray fits the locker or compartment. The Seachoice dual tray measures 14-1/8 by 12-3/8 by 1-1/8 inches in its bullets, the T-H Marine dual holder measures 14.5 by 13.25 by 1.25 inches, and the Attwood tray measures 13.75 by 10.75 by 8.5 inches. Also see our universal battery tray guide for a wider comparison. Measure the locker floor and the height under the lid, and leave room to reach the hold-down without removing neighbouring gear. The ARONOVA tray states no dimensions, so measure the mounting area and compare it with the tray in hand before ordering.
Sizing Notes
- Match the battery group to the tray: the dual holders here fit Group 27 batteries, and the T-H Marine 31 tray fits 31 Series batteries.
- Check the tray dimensions against the mounting space: the Seachoice dual tray measures 14-1/8 by 12-3/8 by 1-1/8 inches in its bullets.
- Match the hold-down to the listing: crossbar and bolts, quick-release buckle, poly strap or stainless steel buckle, as each listing states.
- Confirm the warranty term on the listing before buying: only the Attwood tray states a 90-day term in this group.
- Leave room to reach the hold-down: the crossbar, buckle or strap must be reachable without removing neighbouring gear.
