It slots into the handset where the original B3161 pack sits. Voltage and cell chemistry match the base station's charging circuit exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHirschmann 1200 handset fit:\u003c\/strong\u003e\n    The 1200 handset runs a single-cell NiMH pack at 3.6V nominal. This replacement uses the same cell arrangement and connector orientation as the original B3161, so the handset PCB recognises the pack without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the Hirschmann 1200 base charging circuit and confirmed the BMS accepted charge correctly from the first cycle. Termination voltage and charge acceptance matched the factory spec.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for NiMH cordless packs:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it on charge for a full 16 hours before first use. NiMH cells in cordless phones need a slow initial charge to reach rated capacity — skipping this shortens the usable capacity you get from day one.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than the original battery after replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells ship in a partially discharged state and need three to five full charge and discharge cycles before they reach rated capacity. After a fresh install, the first few sessions will feel noticeably shorter than expected. Each full cycle conditions the cell chemistry and pushes usable capacity higher. By cycle five, the pack should be delivering close to the rated 1200mAh.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge or error light on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH batteries stored for several months can drop below 3.0V, which is under the acceptance threshold for many DECT base charging circuits. The base sees the voltage and refuses to initiate a charge cycle. To recover the pack, use a standalone NiMH charger to push it up to around 3.3V first, then return it to the base. Once the base detects a voltage above its cutoff, the charge cycle will start normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340042272858,"sku":"BWCS-TSU51CL-1","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340042305626,"sku":"BWCS-TSU51CL-2","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340042338394,"sku":"BWCS-TSU51CL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TSU51CL-1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/hirschmann-1200-replacement-battery-36v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
