The RSSR01 runs on a 3.6V nominal Li-ion cell, and this 3.7V unit sits within that same voltage rail — standard practice for single-cell Li-ion packs. Capacity steps up from the original 1300mAh to 2900mAh.\u003c\/p\u003e\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRSSR01 compatibility:\u003c\/strong\u003e The hedge trimmer and grass shear heads both draw from the same battery housing on the RSSR01 handle, so one battery covers both attachments without any adapter or wiring change.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e We ran full charge\/discharge cycles — the BMS held voltage steady under load and tripped cleanly at the low-voltage cutoff, protecting the cell from deep discharge damage.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after storage:\u003c\/strong\u003e Li-ion cells shipped at partial state of charge — run a full charge cycle before first use to let the BMS calibrate the charge endpoints correctly.\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003chr class=\"bpw-desc-divider\"\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhat the capacity increase actually means for this tool\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe RSSR01 is a lightweight single-cell tool — its motor draws relatively low current. A higher-capacity cell at the same voltage delivers more charge per cycle without stressing the tool's circuitry. The extra headroom is useful when switching between attachments mid-job, since the pack doesn't need to recover between tasks.\u003c\/p\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTool stops cutting before the battery reads empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the RSSR01 loses power while the indicator still shows charge remaining, the BMS has likely tripped on a voltage sag under load — common when an older or deeply discharged cell can't sustain the draw. Seat the battery firmly, charge it fully, and test again. If the issue continues, the original cell has degraded and this replacement will resolve it.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43175821770842,"sku":"BWCS-WGF300VX-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43175821803610,"sku":"BWCS-WGF300VX-2","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43175821836378,"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\/timbertech-rssr01-replacement-battery-37v-2900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
