It fits Panasonic cordless telephone handsets that use this OEM part number. When the original pack degrades and stops holding a charge, this battery restores the handset to normal operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGES-PCM02 handset compatibility:\u003c\/strong\u003e\n    These handsets share the same 3.6V NiMH cell configuration, connector pinout, and charge termination voltage. The base station charges via a fixed-current trickle circuit — any replacement must match voltage exactly to avoid charge faults.\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 GES-PCM02-compatible base station. The BMS accepted the pack without error, and charge current tapered correctly at full capacity.\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 for a full 16 hours before first use. NiMH cells in cordless phones reach rated capacity only after a slow, uninterrupted initial charge — shorter charges on the first cycle will leave capacity on the table for weeks.\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 on a new NiMH pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH batteries self-discharge during storage. If the pack sits long enough, its resting voltage drops below the threshold the base station uses to detect a valid battery. The charger reads this as a fault rather than a flat pack. Most Panasonic bases will recover if you leave the handset seated for 30–60 minutes — the trickle pre-charge stage slowly raises the cell voltage until the base accepts it for a full charge cycle. If the error clears and normal charging resumes, nothing else needs to be done.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than expected after fitting the replacement pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells ship in a partially discharged state, and the first two or three cycles typically deliver less than rated capacity. This is a chemistry characteristic, not a defect. Each full charge-and-use cycle conditions the cells and allows capacity to build toward the rated 1200mAh. Run three complete cycles — full 16-hour charge, use until the handset warns of low battery, then return to base — before drawing any conclusions about performance.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340077039706,"sku":"BWCS-P401CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340077072474,"sku":"BWCS-P401CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340077105242,"sku":"BWCS-P401CL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P401CL-1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/sanyo-ges-pcm02-replacement-battery-36v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
