It slots into the handset battery compartment and restores power to the DECT handset unit. Voltage and cell chemistry match the original specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAscotel Office 135 and 135pro compatibility:\u003c\/strong\u003e\n    Both models share the same handset chassis, battery bay dimensions, and 2.4V NiMH voltage rail. One battery covers both variants without modification.\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 NiMH-compatible bench charger. The BMS accepted charge current without thermal event, and cell voltage held stable across the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for NiMH handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base station and leave it for a full 16 hours before the first call. NiMH cells in cordless phones require a slow initial charge to reach rated capacity — skipping this shortens every subsequent cycle.\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 take three to five full charge-discharge cycles to reach rated capacity. On cycle one, you may see noticeably less talk time than expected — this is normal cell conditioning, not a fault. Each full cycle trains the cells to accept a deeper charge. By cycle five, the pack should be delivering close to the rated 700mAh.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station not charging the handset after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the base shows no charge light or an error indicator after a battery swap, the NiMH pack voltage may have dropped below the threshold the base charger expects during storage. Some Ascotel base units will not initiate charge below approximately 2.0V. Remove the handset, wait 30 seconds, reseat it firmly, and check that both charging contacts on the handset and cradle are clean and making full contact. If the base still does not respond, a brief trickle charge via a NiMH-compatible external charger will bring the cell voltage up to the acceptance window.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340001771610,"sku":"BWCS-AST135CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340001804378,"sku":"BWCS-AST135CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340001837146,"sku":"BWCS-AST135CL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AST135CL-1.webp?v=1778367024","url":"https:\/\/batteryweb.com\/products\/ascom-ascotel-office-135-replacement-battery-24v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
