It fits the internal battery bay directly and matches the original cell dimensions of 67.20 × 41.70 × 9.00mm. The OEM part number is 1600A00E0F.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGLM120C and GLM150-27C compatibility:\u003c\/strong\u003e\n    Both meters run on the same 3.7V single-cell Li-Polymer pack with identical physical footprint and connector pinout. The BMS handshake on each model uses the same voltage thresholds, so one pack serves both without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the GLM120C's laser-on measurement loop and monitored BMS cutoff behaviour under sustained sensor load. Cell voltage held within spec across repeated measurement bursts with no unexpected shutdowns.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the GLM120C and GLM150-27C:\u003c\/strong\u003e\n    After fitting a new pack, run a full calibration cycle through the instrument menu before field deployment. The meter maps battery state during that sequence — skipping it causes premature low-battery warnings to appear during your first measurement session on site.\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 GLM120C sat unused in a carry case for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells self-discharge slowly during storage. If the pack drops below approximately 2.5V per cell, the BMS trips into protection mode and refuses charge input entirely. The meter powers on briefly — or not at all — and the charger shows no activity. To recover the pack, apply a low-current trickle charge at around 0.05C until cell voltage climbs above 2.8V, then resume normal charging. Most chargers with a recovery or \"boost\" mode handle this automatically.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGLM120C powers on but shuts off during USB data transfer to a PC\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eUSB data transfer runs the laser controller, display backlight, and USB interface simultaneously — a combined load the BMS can trip on if the cell is partially discharged or degraded. The shutdown is a protection event, not a firmware fault. Charge the pack to at least 3.9V before initiating a transfer session. If shutdowns continue on a fully charged pack, the cell capacity has faded below the threshold the BMS considers safe for that combined draw.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360451854426,"sku":"BWCS-BLM120SL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360451887194,"sku":"BWCS-BLM120SL-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360451919962,"sku":"BWCS-BLM120SL-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BLM120SL-1.webp?v=1778614684","url":"https:\/\/batteryweb.com\/products\/bosch-glm120c-replacement-battery-37v-2450mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
