I bought a huge packet of HEAVY DUTY no-name batteries (not alkaline) from a hardware store. It takes 2 batteries and I probably mow the pasture 3 or 4 times before I have to replace them and it takes me 6 hours to mow, so doing the math, you will get about 24 hours of music off a couple of cheap batteries before you'll need to replace. I would assume you will get much more if you use alkaline. An outstanding feature is that long before the batteries go dead, a woman's voice comes over the radio and says LOW BATTERY, so you get a heads up to change them out before they die. Another feature is that after many hours of use, the unit will check to see if you are still listening and will prompt you to hit the volume button in a few seconds or it will shut off on it's own to save the battery. **Q: How long does the battery last on a full charge?** A: I can usually go about a week and a half on a full charge. I'm really good about waiting until the battery is really low and then doing a full charge before unplugging it. I listen about 7 hours out of a 9 hour day. It takes a long time to charge. **Q: Is the rechargeable battery replaceable** A: 3M ALPHA1100 Rechargeable Li-Ion Battery Pack is replaceable. **Q: Does this have am/fm as well as bluetooth?** A: Thank you for asking. the 3M WorkTunes Connect Hearing Protector with Bluetooth Technology, does not have am/fm capability. If you are looking for both Bluetooth and am/fm radio capability, you will want the 3M Worktunes Wireless Hearing Protection with Bluetooth Technology and AM/FM Radio, model number 90542-3DC. ## Frequently Bought Together - 3M WorkTunes Connect + AM/FM Hearing Protector - 3M Gel Hearing Protector Replacement --- ## 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.bo/products/44636319-3m-worktunes](https://www.desertcart.bo/products/44636319-3m-worktunes) --- *Product available on Desertcart Bolivia* *Store origin: BO* *Last updated: 2026-09-17*
