It fits the 1CVA156, CG650, CG670, CG671, and over a dozen additional GE clinical device models sharing the same voltage rail and connector configuration. Capacity is rated at 21.6Wh — drawn directly from the product spec, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGE CG-series and 1CVA156 platform compatibility:\u003c\/strong\u003e\n    These models share a common 12V power architecture and BMS handshake protocol. The cell format, connector pinout, and charge termination behaviour are consistent across the cluster, which is why one replacement cell covers all listed models.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on GE monitoring equipment. The BMS accepted the cell without fault codes, reached full charge termination correctly, and the delta-V cutoff triggered within expected parameters for Ni-MH chemistry.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test after installation:\u003c\/strong\u003e\n    After fitting this battery, let the device complete its full startup self-test without interruption. GE monitoring equipment runs a BMS verification sequence at boot — cutting power during this sequence causes a false battery fault that persists until the next complete reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on the first charge cycle\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eFresh Ni-MH cells often trigger a conservative charge limit on the first cycle. The device's charge IC applies a tighter delta-V threshold until the cell has completed at least one full charge-discharge cycle. This is normal behaviour — the charge IC is not faulty, and the battery is not underperforming. Run one complete discharge followed by a full, uninterrupted charge before drawing any conclusions about capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice alarming low battery immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eGE monitoring devices store a learned battery profile in the BMS from the previous cell. A new Ni-MH cell has not yet established its voltage curve in the device's memory, so the BMS compares it against the old profile and flags a fault. This is not a cell defect. Run one full charge-discharge cycle to let the BMS recalibrate — after that cycle, the alarm threshold resets to match the new cell's actual voltage behaviour at around 10.5V under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381467480154,"sku":"BWCS-CBP308MD-1","price":105.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381467512922,"sku":"BWCS-CBP308MD-2","price":121.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381467545690,"sku":"BWCS-CBP308MD-3","price":133.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CBP308MD_1.webp?v=1778901051","url":"https:\/\/batteryweb.com\/products\/ge-1cva156-replacement-battery-12v-1800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
