It replaces OEM part numbers Electric 5-2522, 5-2523, 5-2539, 5-2705, 5-2721, and TL96158. If your handset no longer holds a charge or dies quickly off the base, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMulti-part compatibility:\u003c\/strong\u003e\n    These six OEM part numbers share the same 3.6V cell stack, connector pinout, and physical footprint — 46 × 31 × 10.50mm. The handset charging circuit makes no distinction between them, so one battery covers all listed variants.\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 DECT handset platform. The BMS accepted charge from the base station immediately, and cell voltage stabilised correctly across all three cells without triggering a charging fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Ni-MH handsets:\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 cells shipped in a partially discharged state need this slow initial charge to reach rated capacity — skipping it locks in a lower usable capacity from the start.\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\"\u003eNi-MH cells don't hit rated capacity on the first cycle. The chemistry needs three to five full charge-discharge cycles before the cells reach their 700mAh ceiling. If talk time feels short in the first few days, that's normal — it's not a defective battery. Run it down fully, charge it completely, and repeat. By cycle five, capacity should be at or near rated spec.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no charge light or error after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the Ni-MH pack voltage drops too low during storage — typically below 3.0V. The base station's charging circuit expects to see a minimum voltage before it will begin a charge cycle, and a deeply discharged pack falls outside that window. Leave the handset seated in the base for 30 minutes without disturbing it; most base stations will trickle charge at low voltage until the pack rises above the acceptance threshold, at which point the charge indicator will activate. If the light still does not come on, check that the handset contacts are clean and fully seated against the base cradle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339870928986,"sku":"BWCS-MTD716CL-1","price":205.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339870961754,"sku":"BWCS-MTD716CL-2","price":245.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339870994522,"sku":"BWCS-MTD716CL-3","price":275.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MTD716CL-1.webp?v=1778366872","url":"https:\/\/batteryweb.com\/products\/general-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
