Seem a bit heavier but work fine. Given lithium battery reputation for causing fires, I can’t stop wondering what’s the real internal difference with Bosch so I’m being cautious till I get real experience with them. ## Frequently Bought Together - wowrmaykay BAT609 Battery, 18V 4.0Ah Li-ion Battery Replace for Bosch 18V Cordless Power Tools Extended Batteries Rechargeable - Quick BC660 BC1880 Charger for Bosch Tools 14.4V-18V Lithium Battery BAT619G, BAT619, BAT609G, BAT609, BAT618, BAT618G, BAT610G BAT614 etc. - BOSCH GBA18V80 18V CORE18V® Lithium-Ion 8 Ah High Power Battery --- ## 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.tn/products/581712445-4-0ah-replacement-for-bosch-18v-battery-bat609-bat618-bat619g](https://www.desertcart.tn/products/581712445-4-0ah-replacement-for-bosch-18v-battery-bat609-bat618-bat619g) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-03*
