The RD8000 is a handheld cable and pipe detection instrument used to locate buried utilities in the field. Voltage and capacity match OEM spec exactly — 3.7V nominal, 13400mAh (49.58Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRD8000 \/ RD7000+ \/ RD8100 platform fit:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, connector pinout, and BMS handshake protocol. The 09\/ER3223Z13 cell configuration (4LI-18650-1S4P-R1) matches the OEM layout, so the instrument's power management system recognises the pack without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the RD8000's full power-on sequence, including transmitter activation and active locate mode. The BMS held steady through the initialisation current spike and did not trip into protection mode during sustained sensor draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration cycle:\u003c\/strong\u003e\n    After fitting this battery, run a full calibration cycle from the RD8000's instrument menu before heading to site. The device maps battery state during calibration — skipping this step causes the low-battery indicator to trigger early on the first field session, even with a full charge.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS lockout after the RD8000 pack sat unused in a carry case for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge over time. If the RD8000 sits unused long enough, the pack voltage can drop below the BMS recovery threshold — typically around 2.5V per cell — and the protection circuit latches into lockout. At that point the instrument will not power on, and the charger may show no activity. To recover the pack, connect it to a quality Li-ion charger that supports a trickle or recovery charge mode and let it bring the cells up slowly to around 3.0V before switching to normal CC\/CV charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRD8000 readings drifting or logging session resetting mid-survey\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSustained sensor load during an active locate or logging session draws more current than standby, and a degraded or partially charged cell can produce momentary voltage sag below the instrument's operating threshold. When that happens, the RD8000 resets mid-session without a clean shutdown — logged data may be lost or corrupted. This is not a firmware issue. Check resting cell voltage after the session — if it reads below 3.5V immediately after a reset event, the cell capacity has faded and the pack needs replacing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360451952730,"sku":"BWCS-RTD700XL-1","price":80.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360451985498,"sku":"BWCS-RTD700XL-2","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360452018266,"sku":"BWCS-RTD700XL-3","price":106.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RTD700XL-1.webp?v=1778614760","url":"https:\/\/batteryweb.com\/products\/radiodetection-rd8000-replacement-battery-37v-13400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
