It slots directly into the battery compartment and restores full IR output to the remote. Voltage and physical dimensions match the original cell exactly at 53.00 × 33.90 × 5.70mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePro and Pro24 series compatibility:\u003c\/strong\u003e\n    The Pro, Pro24.i, Pro24.r, and Pro24.r v2 all share the same battery bay dimensions and 3.7V single-cell power rail. One SKU covers all four variants — no adapters or modifications needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on RTI Pro hardware. The battery accepted a full charge without interruption and delivered consistent IR trigger voltage across the entire discharge range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSingle-cell remote swap tip:\u003c\/strong\u003e\n    This remote runs on one Li-ion cell, so there is no pairing issue — but confirm polarity before closing the compartment. The positive terminal faces toward the contact marked with a plus sign. A backwards install will leave the remote completely unresponsive and is the most common cause of a failed swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the RTI Pro stops responding mid-session even with a charged battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells develop internal resistance as they age. When that resistance rises high enough, the cell can no longer sustain the brief current spike the IR LED needs to fire a command. The voltage at rest may still read 3.6V on a meter, but under load it dips below the minimum IR trigger threshold. Replacing the cell restores the current delivery the LED requires rather than just topping up voltage.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRTI Pro commands registering only when held close to the receiver\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIR range collapses before battery percentage drops to zero. As the cell discharges below roughly 3.5V, the IR LED pulse weakens and the beam narrows. The remote still functions at close range because the receiver sensor picks up the weaker signal directly. Install a fresh cell and test from normal operating distance — full IR range returns when resting voltage sits at or above 3.7V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416102207578,"sku":"BWCS-RTB240RC-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416102240346,"sku":"BWCS-RTB240RC-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416102273114,"sku":"BWCS-RTB240RC-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RTB240RC-1.webp?v=1779760285","url":"https:\/\/batteryweb.com\/products\/rti-pro-replacement-battery-37v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
