It slots into 2.4V cordless DECT handsets where the original pack has faded and no longer holds a usable charge. Capacity is 1200mAh as rated — same footprint as the original at 50.25 × 28.09 × 14.41mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCross-reference fit — 70AAS2BMJ, 60AAS2BMJ, 6AAS2BMJ:\u003c\/strong\u003e\n    These three GP part numbers refer to the same physical battery format across different production runs. Same voltage rail, same connector orientation, same cell count. If your handset shipped with any of these part numbers printed on the original pack, this battery fits.\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 2.4V NiMH platform. The cell voltage held steady through the discharge curve with no premature cutoff. BMS handshake with the base station charger completed without error on the first dock.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for NiMH cordless handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before using it. NiMH cordless batteries ship partially discharged and need a slow initial charge to reach rated capacity — skipping this results in shorter talk time on the first several cycles.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing a charging error or fault light on a new NiMH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDECT base stations use a delta-V detection method to confirm a NiMH pack is accepting charge. A battery that has been in storage for months can arrive at a resting voltage low enough that the base misreads it as a fault condition rather than a dischargeable cell. The fix is to seat the handset in the base and wait — most bases will retry the charge cycle after 60 to 90 seconds and will accept the pack once it sees the voltage begin to rise. If the error persists beyond two dock attempts, remove the handset, wait 30 seconds, and re-seat it to trigger a fresh detection cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than the original battery for the first few uses\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells go through a conditioning process over the first three to five charge-discharge cycles before they reach rated capacity — this is normal and not a fault. A new pack pulled straight from packaging and used without a full initial charge will deliver noticeably less talk time until the cells are properly conditioned. Run the handset down until the low-battery indicator triggers, then return it to the base for a full charge — repeat this two to three times. By cycle four or five, talk time should match the rated 1200mAh output.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339986370650,"sku":"BWCS-BTM500CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339986403418,"sku":"BWCS-BTM500CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339986436186,"sku":"BWCS-BTM500CL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BTM500CL-1.webp?v=1778366983","url":"https:\/\/batteryweb.com\/products\/gp-replacement-battery-24v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
