It slots into the battery compartment in the handset body and powers the DECT radio, speaker, and display. Capacity figure is from the product specification — 5.4Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSBC 368B handset fit:\u003c\/strong\u003e\n    The 368B uses a 3.6V single-cell Ni-MH pack sized at 49.00 × 42.90 × 14.74mm. This replacement matches that voltage rail and physical footprint. The handset charging circuit expects Ni-MH chemistry — a Li-ion pack at the same voltage would behave differently under trickle charge and should not be substituted.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on a Ni-MH-capable tester. The BMS accepted trickle charge from the base station without flagging an error. Capacity reached rated output after three full conditioning cycles, which is normal behaviour for Ni-MH cells from storage.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on the 368B:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before first use. Ni-MH cordless phone packs arrive partially discharged from storage. A slow first charge lets the cells reach rated capacity — skipping this step will result in shorter talk time on the first few uses.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange reduction on the 368B after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH voltage drops under RF load — the DECT transmitter in the 368B draws a short current spike every time it sends a signal burst to the base. A fresh pack straight from storage sits at a lower state of charge, so that voltage sag is larger than it would be on a fully conditioned cell. The handset interprets sustained low voltage as a weak battery and may reduce transmit power or drop the link. Run three full charge-discharge cycles and the resting voltage stabilises, which keeps the transmit rail within spec during peak draw.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no charge light after fitting new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs shipped from storage can sit below 3.0V, which is under the acceptance threshold some 368B base charger circuits use to detect a valid pack. The base sees the low voltage and withholds charge rather than risk reverse-polarity damage to a deeply discharged cell. Remove the handset, wait 10 seconds, then reseat it firmly — the base retries detection on each insertion. If the charge light still does not appear, check that the handset contacts and base cradle contacts are clean and making full metal-to-metal contact; a thin film of oxidation raises contact resistance enough to drop the detected voltage below 3.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339952619610,"sku":"BWCS-BS980CL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339952652378,"sku":"BWCS-BS980CL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339952685146,"sku":"BWCS-BS980CL-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BS980CL-1.webp?v=1778366983","url":"https:\/\/batteryweb.com\/products\/sbc-368b-replacement-battery-36v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
