It replaces OEM part numbers including BAT160, BAT180, BAT181, BAT189, and 2 607 335 266, among others. The battery slots into the original bay and communicates with the charger through the standard Bosch 18V contact array.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e13618-2G and 1644 series fit:\u003c\/strong\u003e\n    These models share the same 18V Ni-MH platform, mechanical bay dimensions, and contact configuration. The BMS handshake protocol is identical across the BAT160 through BAT189 OEM range, so one cell pack covers all of them.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated trigger-pull events on the 13618-2G and monitored the BMS response to motor-start inrush current. Cell temperature and voltage recovery between bursts stayed within spec across all test cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eNi-MH torque cycling:\u003c\/strong\u003e\n    On first use, run the drill at medium load — mid-range fastening, not full-torque driving — for two full discharge-and-charge cycles. This lets the BMS establish accurate current thresholds before you hit it with maximum motor demand, and prevents false overcurrent cutoffs on early trigger pulls.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff on motor-start inrush during heavy drilling\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on a Bosch 13618-2G under load — driving a large-diameter bit into hardwood, for example — the motor draws a short inrush spike well above its steady-state current. Ni-MH packs have a lower peak discharge tolerance than Li-ion, and if the BMS overcurrent threshold is set conservatively, that spike can trip a cutoff before the motor gets up to speed. This tends to happen more often on a new or recently stored pack whose BMS has no current draw history. Two break-in cycles at medium load calibrate the threshold and reduce false trips significantly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDrill bogs and loses torque mid-hole without cutting out\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the drill slows under load but keeps running — no cutoff, just loss of power — the likely cause is voltage sag across the contact rail. On older Bosch 18V bays, the spring-loaded terminals can develop oxidation that raises contact resistance and drops the voltage the motor actually sees. Clean the battery terminals and the tool bay contacts with a pencil eraser, then check voltage at the contacts under light load. A healthy pack should hold above 16V at the rail; a reading below 15V under moderate load points to either high contact resistance or cell degradation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416071602266,"sku":"BWCS-BST160PW-1","price":100.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416071635034,"sku":"BWCS-BST160PW-2","price":118.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416071667802,"sku":"BWCS-BST160PW-3","price":131.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BST160PW-1.webp?v=1779760116","url":"https:\/\/batteryweb.com\/products\/bosch-13618-2g-replacement-battery-18v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
