It slots into the handset battery compartment and restores power to the handset. Voltage and form factor match the OEM spec: 44.20 × 29.94 × 4.35mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eS9A and S9H handset compatibility:\u003c\/strong\u003e\n    These models share the same battery bay geometry, voltage rail, and connector pinout. One battery covers all four variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on the S9A platform. The protection circuit held charge termination at the correct voltage and responded cleanly to the base station charge current.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on a Li-ion handset battery:\u003c\/strong\u003e\n    Unlike NiMH packs, this Li-ion cell does not need a 16-hour conditioning cycle. Place the handset in the base until the charge indicator clears — typically one full charge cycle from a depleted state is enough to reach rated capacity.\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  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell often ships at partial state of charge after storage. The first one or two cycles may feel shorter than expected — this is normal. The cell reaches rated capacity around cycle three once the electrodes have fully activated. Run two or three complete charge-discharge cycles through normal use before assessing talk time against the 500mAh rating.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHandset not pairing with the base after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRemoving a DECT handset battery cuts power completely, and some Philips S9-series handsets drop their pairing registration when power is lost. The handset will show no signal or fail to ring after reinstall. Re-register the handset using the base station menu — on most S9 models, hold the paging button on the base for five seconds, then follow the on-screen prompt on the handset to complete re-pairing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339916410970,"sku":"BWCS-PHS900CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339916443738,"sku":"BWCS-PHS900CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339916476506,"sku":"BWCS-PHS900CL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PHS900CL-1.webp?v=1778366945","url":"https:\/\/batteryweb.com\/products\/philips-s9a-replacement-battery-37v-500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
