The MD 16904 is a lightweight 500g tool used for trimming lawn edges and cutting back bushes. Voltage and capacity match the OEM specification exactly — 3.7V, 2900mAh, 10.73Wh.\u003c\/p\u003e\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCompatibility — MD 16904 \/ MD16904:\u003c\/strong\u003e Both model references point to the same unit sharing the same 3.7V battery bay, connector, and BMS communication protocol, so one cell covers both.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e We ran full charge and discharge cycles — the BMS held voltage steady under cutting load and triggered the low-voltage cutoff cleanly without dropping the tool unexpectedly mid-use.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge before use:\u003c\/strong\u003e With Li-ion cells, run a full charge cycle before the first cut — this lets the BMS calibrate its state-of-charge tracking accurately from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003chr class=\"bpw-desc-divider\"\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy cell dimensions matter in a compact shear\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe MD 16904 keeps its 500g weight low by using a tightly fitted battery compartment. At 66.65 x 19.50 x 18.50mm, this cell matches the original envelope. An undersized or oversized cell can cause loose seating, poor contact, or a lid that won't close — all of which interrupt power delivery at the connector pins.\u003c\/p\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eShear won't power on after storage — here's why\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells left discharged for extended periods can drop below the BMS recovery threshold, causing the tool to appear dead. The charger may also refuse to initiate a charge cycle. Connect the charger and leave it for 20–30 minutes without interruption — most BMS units will detect the trickle and begin recovery automatically before switching to a normal charge rate.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43175822098522,"sku":"BWCS-WGF300VX-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43175822131290,"sku":"BWCS-WGF300VX-2","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43175822164058,"sku":"BWCS-WGF300VX-3","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WGF300VX-1.webp?v=1775236276","url":"https:\/\/batteryweb.com\/products\/medion-md-16904-replacement-battery-37v-2900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
