It slots into the same battery bay as the original pack and connects to the same charging contacts. Capacity is 1500mAh — match that figure if you're comparing against other aftermarket options.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSBD12, CSD12C, and PTUB17 compatibility:\u003c\/strong\u003e\n    All three models run the same 12V battery rail, share the same physical connector footprint, and draw inrush current within the same BMS threshold window — which is why one cell pack covers all three 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 events on a SBD12 and monitored the BMS response during motor-start inrush. The overcurrent protection tripped at the expected threshold and reset cleanly without latching faults.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst two cycles on Ni-MH:\u003c\/strong\u003e\n    Run the drill through two full discharge-to-charge cycles before using it at maximum torque. Ni-MH cells need conditioning to reach rated capacity — skipping this leaves the pack operating below 1500mAh and can cause premature low-voltage cutoff signals.\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 trigger pull\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the SBD12, a hard trigger pull from rest draws a spike of current in the first milliseconds as the motor spins up. If the BMS reads that spike above its overcurrent threshold — especially on a cold or unconditioned pack — it shuts the output rail immediately. The result looks like a dead battery, even on a freshly charged pack. Letting the pack warm to room temperature and completing two conditioning cycles reduces internal resistance enough to keep the inrush current below the BMS trip point.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising the pack after extended storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs stored for more than a few months can self-discharge below the voltage floor some chargers require before they begin a charge cycle. The charger sees the pack as faulty rather than flat and either blinks an error or does nothing. To recover, apply a short trickle charge using a Ni-MH compatible charger that has a recovery or reconditioning mode — this brings the cell voltage up to the acceptance threshold. Once cells read above approximately 1.0V per cell, the charger should recognise the pack and proceed normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416085790810,"sku":"BWCS-BS3300PW-1","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416085823578,"sku":"BWCS-BS3300PW-2","price":92.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416085856346,"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\/ramset-sbd12-replacement-battery-12v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
