Parts Desk Insights
The NBH31SSCOPT is the correct tray when you’re running Optima D27M or D31M batteries — these batteries won’t sit securely in a standard rectangular tray due to their round-cell housing. The shaped inserts are what make this tray work: they hold the Optima’s cylindrical cells in place without any modification or improvisation. The stainless steel buckle is a worthwhile feature on any boat that sees saltwater, where plastic buckles tend to corrode and fail over time. The 8 mounting slots give you flexibility to position the tray in tight or awkward battery compartments. For standard Series 24 or 27 battery trays, see the T-H Marine NBH24PDP Series 24 Tray or the T-H Marine NBH27PDP Series 27 Tray.
