Returned it and ordered this battery. Fit perfect, and had a charge on it. Went ahead and plugged it in to my battery tender to fully charge it, but it started the bike right away. Great battery for the price. Trying to find a motorcycle battery unless it's a Harley can be tricky, or very expensive. ### ⭐⭐⭐⭐⭐ that feature is totally useless. They claim you can mount your cables (say ... *by G***E on June 4, 2015* Very tight fit in a 2010 Yamaha FJR but it works well. For those reading this that may be contemplating this for their FJR know that the brace that goes across the battery in two pieces that are screwed together will have to be bent a bit and the end that connects to the side. Basically, you are "bowing" the brace because the batter is about a millimeter or two higher than the stock battery and the brace won't mate up. Once I bowed one end, and then squeezed the two pieces together I was able to get the screw started. After the brace is tight, that battery isn't going anywhere and has zero chance of moving within the battery holder. Now as to the double post connector, that feature is totally useless. They claim you can mount your cables (say on the top) and then your accessory leads on the side. No, you can't. The two screws will meet in the middle and you will never get them tight unless you back them off with washers, but if you do, you are only going to get a few twists of tightness before the screws hit. I wouldn't trust that. If they really intended for one to do that, they posts should have had offset screw holes for the top and side so that the screws just missed each other. However, given the size of the battery and the size of the post, I doubt that is possible. Anyway, good battery. I am happy with it so far. ### ⭐⭐⭐⭐⭐ Battery works great *by F***D on August 19, 2024* The battery arrived on time, due to battery had to be shipped ground USPS. Fit into my Yamaha perfectly and works great. ## Frequently Bought Together - Motobatt MBT14B4 AGM Factory Activated Replaces 13 AH Yuasa YT14BBS, GT14B4, Yamaha FJR1300,MT01, Raider, Stratoliner, Hyosung - CARBTUNE PRO 4 W/Pouch - FOVAL 2-Amp Automatic Battery Charger, 6V and 12V Smart Car Battery Charger Maintainer, Trickle Charger and Battery Desulfator for Motorcycle, ATV, Boat, Lawn Mower Lead Acid Batteries --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/187137585-mbt14b4-agm-factory-activated-replaces-13-ah-yuasa-yt14bbs-gt14b4](https://www.desertcart.us/products/187137585-mbt14b4-agm-factory-activated-replaces-13-ah-yuasa-yt14bbs-gt14b4) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-24*
