Capacity sits at 54Wh — enough headroom for tools that cycle between burst and idle loads. The physical footprint matches the original slide-rail format at 116 x 80.3 x 65mm.\u003c\/p\u003e\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBroad Bosch 18V compatibility:\u003c\/strong\u003e These models share the same 18V power rail, slide-mount connector, and BMS communication protocol — which is why one pack covers garden sprayers, fans, and drills from the same platform.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e We ran full charge\/discharge cycles — the BMS held voltage steady under load and tripped the low-voltage cutoff cleanly without requiring a manual reset.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge tip for Li-ion packs:\u003c\/strong\u003e Charge fully before first use — this lets the BMS calibrate its state-of-charge tracking and avoids early capacity drift across the cell group.\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003chr class=\"bpw-desc-divider\"\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Easy Spray and Universal Pump draw differently from the same pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003ePump and sprayer tools pull current in short, high-demand bursts when pressurising the line, then drop to near-zero between strokes. Fan tools draw a steadier, lower continuous current. A 3000mAh pack handles both profiles because the BMS is rated for the peak draw of the pump without triggering an overcurrent fault during pressurisation cycles.\u003c\/p\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTool powers on then cuts out immediately — here is what is happening\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is almost always a depleted cell triggering the BMS protection circuit, not a faulty tool. When one cell in the pack drops below the low-voltage threshold, the BMS disconnects output to protect the chemistry. The fix is a full, uninterrupted charge cycle — if the charger shows a fault light instead of completing, the pack has likely deep-discharged beyond recovery and needs replacing rather than recharging.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43175810433114,"sku":"BWCS-BMU180PX-1","price":90.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43175810465882,"sku":"BWCS-BMU180PX-2","price":106.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43175810498650,"sku":"BWCS-BMU180PX-3","price":118.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BMU180PX-1.webp?v=1775236243","url":"https:\/\/batteryweb.com\/products\/bosch-universal-pump-18v-replacement-battery-18v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
