That shaky feeling disappeared the second I installed this NOCO BT24S battery tray. The heavy-duty strap grabs the battery like a vice, no slipping, no sliding. Now my battery stays put no matter how bumpy the ride gets—no surprises, no stress. It’s like finally cutting ties with all the drama and having something solid I can count on. If you want peace of mind and zero battery drama, this tray is the real deal. Trust me, once it’s holding your battery, you’ll never let go either. 🔋💯✨ Review: Looks like good quality, thanks ## Features - A rugged battery tray for group 31 batteries, including marine, RV, camper, and trailer batteries. - Features a heavy-duty 42-inch hold-down strap with nylon resistant webbing that withstands a tensile load of over 120 kilograms of force. - Impact-resistant down to minus 20 degrees Fahrenheit, withstands acid, gas, oil and other contaminants, and immune to UV exposure. - Keeps your battery securely mounted and limits battery movement during transportation and operation. - International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00E3ALEKI | | Automotive Fit Type | Universal Fit | | Battery Type | Alkaline | | Best Sellers Rank | #195,778 in Automotive ( See Top 100 in Automotive ) #79 in Car Battery Trays | | Brand Name | NOCO | | Compatible with Vehicle Type | RV | | Country of Publication | USA | | Customer Reviews | 4.5 4.5 out of 5 stars (2,696) | | Global Trade Identification Number | 00046221130508 | | Included Components | 42-Inch Battery Trap, Group 31 Battery Tray | | Item Type Name | NOCO BT31S Group 31 Heavy-Duty Battery Tray For Marine, RV, Camper And Trailer Batteries | | Item Weight | 0.59 Pounds | | Manufacturer | NOCO | | Manufacturer Part Number | BT31S | | Model Number | BT31S | | Number Of Cells | 6 | | OEM Equivalent Part Number | BT31 | | Size | One Size | | Terminal | Marine Terminal | | UPC | 046221130508 | | Unit Count | 1 Count | | Voltage | 12 Volts | ## Product Details - **Battery cell composition:** Alkaline - **Brand:** NOCO - **Size:** One Size - **Vehicle service type:** RV - **Voltage:** 12 Volts ## Images ![NOCO Black one size Group 31 Heavy-Duty Battery Tray for Marine, RV, Camper and Trailer Batteries, BT31S - Image 1](https://m.media-amazon.com/images/I/71XdxbWyYsL.jpg) ## Questions & Answers **Q: I have limited space so could I get the measurements of this tray?** A: Above illustration shows a little over 14. **Q: Will this replace a factory tray** A: Depends.
