It fits the standard battery bay and connects via the original multi-pin interface. Capacity figures are taken directly from product data — 38.48Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRD8000 \/ RD8100 \/ RD7000+ platform fit:\u003c\/strong\u003e\n    These models share the same 3.7V single-cell architecture, bay dimensions, and BMS handshake protocol. One pack covers the full locator family without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the RD8000 power-on sequence and active signal-tracing load. The BMS negotiated correctly, held voltage under sustained transmitter and receiver draw, and did not trigger a low-voltage cutoff during signal lock.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on RD8000 \/ RD8100:\u003c\/strong\u003e\n    After fitting this pack, run a full calibration cycle through the instrument menu before field deployment. The RD8000 maps battery state during calibration — skipping it causes premature low-battery warnings during your first locating 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 sat unused in a carry case for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the RD8000 pack drops below approximately 2.5V per cell, the BMS trips a protection latch and blocks charge input entirely — the charger sees the pack as absent. This is a safety state, not cell failure. To recover, apply a low-current trickle charge at around 0.1C for 15–30 minutes to lift cell voltage above the BMS recovery threshold, typically 3.0V, then switch to standard charge. Most quality chargers with a recovery or \"wake\" mode handle this automatically.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRD8000 display showing erratic battery percentage immediately after fitting a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe RD8000 uses a voltage-threshold method to estimate charge state. A new cell has a slightly different discharge curve than the degraded pack it replaced, so the instrument's indicator recalibrates over the first full charge-discharge cycle. The percentage readout will stabilise after one complete cycle — charge to 100%, run the instrument through a normal locating session to drawdown, then recharge fully. After that cycle, the display tracks accurately.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360452051034,"sku":"BWCS-RTD700SL-1","price":70.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360452083802,"sku":"BWCS-RTD700SL-2","price":83.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360452116570,"sku":"BWCS-RTD700SL-3","price":93.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RTD700SL-1.webp?v=1778614760","url":"https:\/\/batteryweb.com\/products\/radiodetection-rd8000-replacement-battery-37v-10400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
