It fits the GBM 7.2, GBM 7.2 VE-1, GBM 7.2 VES-2, GDR50, and several additional models. The pack slots directly into the original battery bay and communicates with the tool's power circuit without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGBM 7.2 platform fit:\u003c\/strong\u003e\n    The GBM 7.2 series shares a 7.2V rail and a common battery connector across its variants. All listed models pull from the same voltage and physical form factor, which is why one pack covers the full range including OEM part numbers 2 607 335 032, 033, 073, and 153.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated trigger-pull loads on a GBM 7.2 VE-1. The cell block held voltage above the low-cell cutoff threshold through full discharge, and the charger accepted the pack without rejection flags on multiple cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eNi-MH break-in on motor start:\u003c\/strong\u003e\n    On first use, run the drill at half load for two cycles before applying maximum torque. Ni-MH cells deliver current unevenly until the pack has been cycled — running full torque immediately can create cell imbalance that shortens overall capacity over time.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eVoltage sag on the GBM 7.2 under sustained drilling load\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe GBM 7.2 is a light-to-medium drill, but continuous use in dense material draws sustained current that Ni-MH cells handle differently than Li-ion. As cell temperature rises inside the compact housing, internal resistance increases and the terminal voltage sags. The tool may feel underpowered even with a charged pack. This is not a fault — it is a chemistry characteristic. Let the pack rest for 10 minutes between extended sessions to allow cell temperature to drop and internal resistance to recover.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising the pack after it has been sitting unused\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs self-discharge during storage — faster than Li-ion. If a pack has sat unused for several months, the resting voltage can fall below the threshold the charger uses to confirm a valid battery is present. The charger may show no response or flash an error. To recover it, briefly connect the pack to a known-good 7.2V Ni-MH charger in trickle mode for 15–20 minutes to bring the cell voltage up to approximately 6.5V, then allow the charger to resume its normal charge cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416068784218,"sku":"BWCS-BST720PW-1","price":66.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416068816986,"sku":"BWCS-BST720PW-2","price":77.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416068849754,"sku":"BWCS-BST720PW-3","price":85.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BST720PW-1.webp?v=1779760040","url":"https:\/\/batteryweb.com\/products\/bosch-gbm-72-replacement-battery-72v-2100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
