It slots into the same bay as the original pack and works with the factory charger. Capacity is rated at 3300mAh (31.68Wh) from the product specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBBM596B platform fit:\u003c\/strong\u003e\n    The BBM596B and its variants share a common 9.6V battery bay, connector pitch, and thermistor pin layout. This pack matches all three — voltage rail, connector, and thermistor signal — so the charger handshake completes without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through motor-start inrush cycles on a 9.6V drill platform. The BMS held the overcurrent threshold across repeated trigger pulls without tripping. Cell voltage recovery after each load cycle stayed within spec.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use drill cycling:\u003c\/strong\u003e\n    On first use, run the tool at half load for two cycles before full-torque applications. This lets the BMS log the motor inrush draw and set its overcurrent protection thresholds accurately before you push the tool hard.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff on BBM596B motor-start inrush surge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on a stalled or heavily loaded drill, current spikes sharply in the first 80–150ms. On a Ni-MH pack that has been sitting discharged, internal resistance is elevated, which amplifies the voltage drop at the rails. The BMS reads this as an overcurrent event and cuts output before the motor reaches speed. Running two half-load cycles first lets cell resistance normalise and gives the BMS accurate inrush data to work from.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising a new BBM596B pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs that have been stored can self-discharge below the charger's acceptance voltage — typically under 8.5V on a 9.6V pack. Most chargers will blink an error or sit idle rather than begin the charge cycle. To recover, place the pack in the charger and check for any pulse or trickle mode; many FLEX chargers attempt a short trickle pulse at low voltage before switching to full charge. If the charger still shows a fault after five minutes, measure pack voltage at the terminals — if it reads above 7V, the cells are recoverable and a second insertion usually clears the fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416068685914,"sku":"BWCS-BST974PX-1","price":87.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416068718682,"sku":"BWCS-BST974PX-2","price":102.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416068751450,"sku":"BWCS-BST974PX-3","price":113.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BST974PX-1.webp?v=1779760040","url":"https:\/\/batteryweb.com\/products\/flex-bbm596b-replacement-battery-96v-3300mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
