It fits the base+, pro+, tiga, and Aperto A550 L series wireless transmitters. When the original cell degrades, this replacement restores full wireless control without replacing the remote unit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ebase+ \/ pro+ \/ tiga \/ Aperto A550 L compatibility:\u003c\/strong\u003e\n    These models share the same 24V power rail, physical pack dimensions (107.40 × 49.50 × 19.40mm), and connector layout — all draw from a common internal platform, so one battery fits the full range.\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 the bench, confirmed the BMS holds the 24V nominal rail, and verified cell balance across the Ni-MH stack before dispatch.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after storage:\u003c\/strong\u003e\n    Ni-MH cells lose charge during warehouse storage. Before pairing the remote, run a full charge cycle on the transmitter — a partial cell voltage at first power-on can cause the remote to fail its self-test and show no response at the receiver.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the SOMMER remote goes offline after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSOMMER's smart remote transmitters run a handshake sequence with the receiver unit every time power is interrupted. After fitting a new battery, the transmitter needs up to 60 seconds to complete this re-join before it will respond to button presses. Pressing buttons during this window does nothing — it is not a pairing failure. Wait the full 60 seconds, then test the remote from within range of the garage receiver.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alert appears immediately after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs stored for extended periods self-discharge to a resting voltage below the receiver's low-battery alert threshold — even though the cell itself is not faulty. The SOMMER receiver reads this low resting voltage and triggers the alert before the pack has had a chance to recover. Fit the battery, place the remote on charge for a full cycle, and the alert will clear once the cell voltage climbs above the detection threshold. Do not assume the replacement pack is defective until after that first full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416142315610,"sku":"BWCS-SMR550AF-1","price":60.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416142348378,"sku":"BWCS-SMR550AF-2","price":71.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416142381146,"sku":"BWCS-SMR550AF-3","price":79.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMR550AF-1.webp?v=1779760485","url":"https:\/\/batteryweb.com\/products\/sommer-base-replacement-battery-24v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
