It uses the same voltage rail and physical form factor as the original, so it seats directly into the radio body without modification. Capacity is rated at 1200mAh (12.96Wh) — identical to the stock specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e152, 154, and 156 compatibility:\u003c\/strong\u003e\n    These three Wilson models share the same battery bay geometry, contact layout, and 10.8V power rail. The BMS handshake is identical across the series, so one replacement pack covers all three without any adapter or wiring change.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack under simulated PTT load on a Wilson 152 chassis. The BMS held voltage through repeated transmit bursts without triggering overcurrent cutoff, and the cell stack recovered cleanly to full charge between cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion on the charger dock:\u003c\/strong\u003e\n    If the dock LED shows a fault on first insertion, remove the pack and wipe the gold contact strip with a dry cloth before reseating. Wilson dock firmware checks contact resistance before accepting the BMS handshake — a single oxidation layer on a new cell can prevent the charge cycle from starting.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Wilson 152 cuts out mid-transmission on a new Ni-MH pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells ship at storage voltage — typically 1.0–1.1V per cell, which puts a 9-cell 10.8V pack around 9.0–9.9V at rest. When PTT is pressed, transmit current spikes sharply and the BMS sees voltage drop below its cutoff threshold before the cells have been properly conditioned. The radio interprets this as a depleted pack and cuts RF output to protect the finals. Running two full charge-discharge cycles before heavy use lets the cells reach working capacity and stabilises the voltage floor under transmit load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after a full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWilson's bar indicator reads voltage thresholds, not charge percentage. A new Ni-MH pack straight off the charger sits at surface charge voltage — typically 1.40–1.45V per cell — which drops to the nominal 1.2V resting level within minutes of light use. The radio samples voltage after this settling period, so the indicator corrects itself during the first transmission cycle. If the low bar persists after the first full PTT session, check that the dock completed a full charge cycle and did not terminate early due to a contact fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426321301594,"sku":"BWCS-UPX500TW-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426321334362,"sku":"BWCS-UPX500TW-2","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426321367130,"sku":"BWCS-UPX500TW-3","price":55.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-UPX500TW-1.webp?v=1779930681","url":"https:\/\/batteryweb.com\/products\/wilson-152-replacement-battery-108v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
