It replaces part number SL30013 and restores handset operation when the original cell no longer holds a charge. The physical dimensions are 29.75 × 20.80 × 10.04mm — confirm these match your existing battery before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMD9300–MD9700 platform fit:\u003c\/strong\u003e\n    These four models share the same handset battery bay, connector orientation, and 2.4V supply rail. One battery SKU covers the full range 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 charge and discharge on the MD9300 handset platform. The base station accepted the pack without fault lights, and the BMS responded correctly at both low-voltage cutoff and full-charge termination.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Ni-MH handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before first use. Ni-MH cells shipped in storage-depleted state need a slow initial charge to reach rated capacity — skipping this step is the single most common reason a new battery underperforms the original.\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 no charge light on a fresh Ni-MH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH batteries lose voltage during warehouse storage. If the cell sits long enough, its resting voltage drops below the threshold the base station uses to detect a valid pack. The base then shows no charge activity — not because the battery is faulty, but because the charger circuit won't initiate at that voltage. Most Switel bases recover the pack automatically within 20–30 minutes once a trickle current begins. If the charge light still hasn't appeared after an hour, remove the battery, check the contact pins for debris, and reseat firmly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than the original battery after the first few calls\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is normal Ni-MH behaviour and not a defect. A new Ni-MH cell requires three to five full charge-discharge cycles before it reaches its rated 400mAh capacity. Each cycle, the cell's internal crystal structure aligns more fully, and available capacity increases noticeably. Run the handset until it signals low battery, return it to base for a full charge, and repeat — by cycle four or five, talk time stabilises at the rated level.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340003803226,"sku":"BWCS-ADL780CL-1","price":20.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340003835994,"sku":"BWCS-ADL780CL-2","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340003868762,"sku":"BWCS-ADL780CL-3","price":25.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ADL780CL-1.webp?v=1778367023","url":"https:\/\/batteryweb.com\/products\/switel-md9300-replacement-battery-24v-400mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
