Amazing, so nice to not have to rely on the stupid strap just to keep the lid on in a little aluminum boat with a trolling motor. The lid snaps on firmly, but can still be opened easily, and enough room inside for a small Noco maintainer/charger, even with a large group 27 battery in it.

As a mobile RV repair service, we only use products we trust — and the NOCO Snap-Top BG27 Battery Box is one of them. We’ve installed these on multiple RVs and campers for our clients, and they’ve proven to be durable, weather-resistant, and reliable every time. It fits Group 27 batteries perfectly, and the snap-top lid locks securely, offering great protection from moisture, dirt, and impact. The heavy-duty plastic construction holds up well in harsh conditions, and the built-in handles make it easy to transport and install. The included strap is also a nice extra for securing the box in place. We highly recommend this to DIYers and fellow professionals alike — it’s affordable, dependable, and field-tested. Pros: Ideal fit for Group 27 batteries Tough, weather-resistant construction Easy to install and carry Great for RVs, boats, campers, and trailers Trusted by professionals Cons: None so far — we’ve had zero issues with quality or fit Whether you're storing a battery or installing it in a vehicle, this box gets the job done right.

Bought this for a marine battery at our driveway gate. The two I bought from two different auto parts stores failed. Clips broke after two months, lid started leaking, they were not well built. I tried this one and the overall construction is better. The lid locks closed. It’s vented in a manner where the biz doesn’t fill up with water when it rains. Strongly recommend for this application
