It slots directly into the handset battery compartment and restores wireless operation away from the base station. Dimensions are 30.30 × 42.60 × 14.30mm — check these against your existing pack before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFF888 and FF988 compatibility:\u003c\/strong\u003e\n    Both handsets share the same battery bay dimensions, connector pin layout, and 3.6V NiMH voltage rail. One battery covers both models 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 full charge and discharge passes on DECT handset hardware. The cell voltage held within spec across cycles and the handset registered a normal charge state on the base station cradle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after installation:\u003c\/strong\u003e\n    Place the handset in the base for a full 16 hours before first use. NiMH packs shipped from storage are partially discharged — a slow initial charge lets the cells reach rated capacity properly.\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\"\u003eNiMH cells need three to five full charge and discharge cycles before they reach rated capacity. A new pack will feel weak on day one — that is normal chemistry, not a fault. Each full cycle conditions the cells and increases usable capacity incrementally. By cycle five, the pack should be performing at its rated 600mAh level.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing a charge error or no-charge light after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a NiMH pack sits in storage, its resting voltage drops below the threshold some base stations require to begin a charge cycle. The base sees the low voltage and flags an error rather than starting the charge. Remove the handset, leave it out for 30 seconds, then reseat it firmly in the cradle. If the error persists, the pack voltage may need a boost — place it in the base for 10 minutes, remove it again, and reseat; this often clears the fault and triggers a normal charge cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340042698842,"sku":"BWCS-SX100CL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340042731610,"sku":"BWCS-SX100CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340042764378,"sku":"BWCS-SX100CL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SX100CL-1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/audioline-ff888-replacement-battery-36v-600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
