It matches the original pack voltage and connector footprint. Cross-references include BAT011, BH1214MH, and 26 additional OEM part numbers covering the full 12V Ni-MH platform.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e12V Ni-MH platform compatibility:\u003c\/strong\u003e\n    The 3300K, 3305K, 3310K, and 330K share a common 12V rail, connector geometry, and BMS handshake protocol — one cell pack design covers the entire group without modification.\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 sequences on a 3305K. The BMS held inrush current within spec on each start, and cell temperature stayed within normal range across sustained fastening runs.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eNi-MH motor break-in on the 3300K platform:\u003c\/strong\u003e\n    On first use, run the drill at half load for two full discharge-charge cycles before applying maximum torque. This lets the BMS profile the motor's inrush current draw and set accurate overcurrent thresholds before heavy-duty use.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS overcurrent trip on trigger-pull inrush — why the 3300K cuts out instantly\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 3300K motor pulls a short inrush spike the moment you squeeze the trigger — often three to five times the running current. On a new or cold pack, the BMS may read that spike as an overcurrent fault and cut power before the motor completes one rotation. Ni-MH cells have lower internal resistance than older Ni-Cd packs, but a fresh pack straight from storage hasn't been profiled by the BMS yet. Running two half-load break-in cycles lets the BMS calibrate its trip threshold to the actual motor signature and stop false cutoffs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTool bogs or loses torque mid-screw — voltage sag under load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the drill starts strong then weakens as the fastener tightens, voltage sag is the likely cause. High contact resistance at the battery terminals or worn brush contacts inside the tool causes the rail voltage to drop under sustained load. Clean the battery contact points on both the pack and the drill with isopropyl alcohol and check for carbon buildup on the motor brushes. Rail voltage on a healthy 12V Ni-MH pack under load should hold above 10.5V — measure at the terminals while the motor is running.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416086085722,"sku":"BWCS-BS3300PW-1","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416086118490,"sku":"BWCS-BS3300PW-2","price":92.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416086151258,"sku":"BWCS-BS3300PW-3","price":102.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BS3300PW-1.webp?v=1779760223","url":"https:\/\/batteryweb.com\/products\/bosch-3300k-replacement-battery-12v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
