All three models share the same voltage rail and physical pack format, so one SKU covers the group. Capacity is rated at 18Wh from the product data — use that figure, not third-party listings.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSTB61, STB63, and STB65 compatibility:\u003c\/strong\u003e\n    These three Strapex strapping tools share a common 12V battery platform with the same connector pinout and pack dimensions. The BMS handshake across all three models accepts the same charge termination signal, so no firmware or connector adaptation is needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated motor-start inrush events on an STB-series strapping tool. The BMS held through repeated trigger pulls without overcurrent tripping, and charge acceptance was clean from a depleted state.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eStrapping tool cycle care:\u003c\/strong\u003e\n    On first use, run two full strap-and-tension cycles at reduced tension settings before applying maximum torque — this lets the BMS log actual inrush current from your specific tool's motor condition before setting its overcurrent threshold.\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 tensioning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eStrapping tools draw a sharp current spike the moment the tensioning motor fires. On a Ni-MH pack that has been in storage, cell internal resistance is elevated, which makes that inrush spike look larger to the BMS than it would on a conditioned pack. The BMS may interpret this as an overcurrent fault and cut the output before the motor reaches operating speed. Running two light-load cycles first lowers cell impedance and brings the inrush current back within the BMS acceptance window.\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 cells self-discharge over storage — if the pack sits long enough, individual cells can drop below the charger's minimum acceptance voltage, typically around 0.9V per cell. The charger sees a pack voltage too low to confirm cell count and refuses to begin a charge cycle. The fix is a trickle pre-charge: place the pack on the charger, remove and reseat it twice to force a fresh handshake, then allow up to 15 minutes for the charger to detect rising cell voltage before beginning its normal charge profile. If the charger still does not respond, check that each cell group reads above 0.9V with a multimeter before assuming the pack is failed.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416085200986,"sku":"BWCS-BS3455PW-1","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416085233754,"sku":"BWCS-BS3455PW-2","price":89.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416085266522,"sku":"BWCS-BS3455PW-3","price":98.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BS3455PW-1.webp?v=1779760222","url":"https:\/\/batteryweb.com\/products\/strapex-stb65-replacement-battery-12v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
