It slots into the handset battery compartment and connects directly to the charging circuit. Dimensions are 45.60 × 31.30 × 10.60mm — verify these against your existing cell before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCompatible across the PM38\/PMP38 handset range:\u003c\/strong\u003e\n    These models share the same 3.6V three-cell Ni-MH format and identical connector pitch, so one battery covers the full handset lineup without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on a PMP3860 handset. The BMS accepted the pack without error, and charge termination triggered correctly at peak voltage delta.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge cycle on Ni-MH cordless packs:\u003c\/strong\u003e\n    After installing, seat the handset in the base for a continuous 16-hour charge before first use. Ni-MH cells shipped from storage need this slow initial charge to reach rated capacity — cutting it short leaves you with noticeably shorter talk time from day one.\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 Ni-MH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eCasio DECT bases use a voltage-sensing circuit to confirm a valid battery is present before starting a charge cycle. A Ni-MH cell that has sat in storage for months can drop below the 3.0V threshold that triggers acceptance. When that happens, the base flashes an error light or simply shows no charge indicator. Place the handset in the base for 30 minutes — most bases will attempt a trickle pre-charge that brings the cell back above the acceptance voltage, after which normal charging resumes.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHandset loses pairing with the base after battery removal\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome Casio DECT handsets store pairing data in volatile memory that clears the moment battery power is removed. Swapping the battery can leave the handset unregistered, even if it was paired before. To fix this, locate the registration button on the base — usually labelled FIND or REG — hold it for five seconds, then follow the handset menu to re-register. The process takes under two minutes and restores full call functionality.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339963039834,"sku":"BWCS-CPJ464CL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339963072602,"sku":"BWCS-CPJ464CL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339963105370,"sku":"BWCS-CPJ464CL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPJ464CL-1.webp?v=1777949695","url":"https:\/\/batteryweb.com\/products\/casio-pm38bat-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
