Great fit. ### ⭐⭐⭐⭐⭐ 2nd purchase *by A***R on 29 May 2025* Brilliant, ideal for buying the best value/spec tool and using my existing batteries ### ⭐⭐⭐⭐ Is a decent adaptor *by D***1 on 5 April 2023* This was great for fitting my bosch and converting it to fit makita . I used it for my makita radio it works but the battery and adapter are bigger than a normal makita battery and can't shut the radio properly Apart from that it does what is says Also having the USB port mean you can charge a phone if needed. Good but not 5 stars due to the size diffidence . --- ## 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.hr/products/448878543-bs18mt-adapter-for-bosch-professional-18v-system-gba-battery-works](https://www.desertcart.hr/products/448878543-bs18mt-adapter-for-bosch-professional-18v-system-gba-battery-works) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-09*
