It fits the TTC Torque Tool Tester and TTC-1-5N models used for material hardness measurement in field and laboratory environments. Dimensions are 51.60 × 42.80 × 14.40mm — verify against your existing pack before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTTC series platform compatibility:\u003c\/strong\u003e\n    The TTC-1-5N and TTC Torque Tool Tester share the same battery bay, connector orientation, and 3.6V supply rail. The BMS on these instruments monitors cell voltage directly — swapping to an incorrect voltage chemistry triggers an immediate low-battery flag on the display.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the TTC instrument's power-on initialisation cycle and probe activation sequence. The BMS held steady through the brief current spike at sensor power-up and settled to a stable draw during sustained measurement logging.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use calibration step:\u003c\/strong\u003e\n    After fitting this pack, run a full calibration cycle through the TTC instrument menu before starting a measurement session. The instrument maps battery state during calibration — skipping this step causes premature low-battery warnings to appear on your first set of readings.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS lockout after a TTC tester sat unused in a carry case for months\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge slowly during storage. If a TTC tester sits unused long enough, the pack voltage can drop below the BMS recovery threshold — typically around 3.0V for a 3.6V Ni-MH pack. At that point the instrument sees the battery as absent or faulty and refuses to power on. Connecting the charger for a full uninterrupted charge cycle is the correct first step — the BMS needs sustained input voltage to exit the sleep state and begin accepting charge current.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReadings drifting or resetting mid-session on the TTC display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis usually happens when the battery voltage sags under the sustained current draw of continuous hardness measurement cycles. A depleted or degraded Ni-MH cell cannot hold voltage under load, and the instrument's processor resets when supply voltage drops below its operating floor. The fix is a full charge before a measurement session — if drift reoccurs on a freshly charged pack, measure resting cell voltage with a multimeter. A healthy 1600mAh Ni-MH pack at full charge should read at or above 3.6V at rest.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360529252442,"sku":"BWCS-SDT150SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360529285210,"sku":"BWCS-SDT150SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360529317978,"sku":"BWCS-SDT150SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SDT150SL-1.webp?v=1778615962","url":"https:\/\/batteryweb.com\/products\/shimpo-ttc-testers-replacement-battery-36v-1600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
