It fits the full receiver series that shares the same battery bay and connector, including the 5700 Receiver, 5800, and 54344 variants. Capacity figures are drawn from the product specification — not extrapolated from a third-party source.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e5700 and 5800 receiver compatibility:\u003c\/strong\u003e\n    Both receivers use the same 7.4V nominal voltage rail, identical battery bay dimensions, and the same BMS handshake protocol. A single pack covers the platform — no connector modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the 5700's power management circuit. The BMS negotiated charge termination correctly, and the receiver accepted the pack without triggering a battery fault code on the status display.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eField deployment prep for GNSS receivers:\u003c\/strong\u003e\n    After fitting this pack, run a full initialisation cycle through the receiver before heading to site. The 5700 and 5800 map battery state during startup, and a skipped cycle can produce premature low-battery warnings during the first logging session — even with a fully charged pack.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the 5700 receiver shuts down mid-survey with a new battery fitted\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 5700's power circuit draws a brief current spike when the internal GNSS engine locks onto satellites and begins logging. If the replacement pack's BMS has a conservative overcurrent threshold — common in cells that haven't been through a full charge cycle — this spike can trip the protection circuit before the receiver reaches steady-state draw. The result looks like a flat battery, but it's a BMS event. Running one complete charge-discharge cycle before field use resets the BMS headroom and eliminates most of these cutoffs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReceiver shows incorrect battery percentage immediately after a new pack is installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 5700 and 5800 use a voltage-threshold method to estimate remaining charge — there is no separate fuel gauge IC calibrating cell state. When a new pack is installed, the receiver's last stored voltage reference no longer matches the new cell's discharge curve, so the displayed percentage can jump or read low. Charge the pack to full (8.4V at the pack terminals), then run the receiver through one complete discharge in the field. The displayed percentage will track correctly from that point forward.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360745128026,"sku":"BWCS-LI1HL-1","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360745160794,"sku":"BWCS-LI1HL-2","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360745193562,"sku":"BWCS-LI1HL-3","price":46.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LI1HL-1.webp?v=1778616259","url":"https:\/\/batteryweb.com\/products\/trimble-5700-replacement-battery-74v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
