It slots directly into the clipper housing and powers the motor that drives the cutting blade. Capacity is 2.16Wh, matching the original specification from Moser.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e1591B and 1591Q compatibility:\u003c\/strong\u003e\n    Both clipper variants run the same 1.2V motor rail and use an identical battery footprint — 49.90 × 14.30 × 14.30mm. The BMS handshake and charge termination logic are shared across the two models, so this single cell works in either.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the 180AAH through charge cycling on a 1591B unit. The BMS reached delta-V termination cleanly, and the motor held consistent blade speed through the full discharge curve without mid-cycle voltage collapse.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-rinse charging precaution:\u003c\/strong\u003e\n    After rinsing the ChroMini Pro blade under water, let the clipper air dry for at least 30 minutes before connecting the charging lead. Moisture bridging the charging contacts trips a BMS protection fault that the device reports as a dead battery rather than a charging error.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCapacity fade from daily partial charging on the ChroMini Pro\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells in clippers used daily tend to be topped up after every session rather than run to a low state first. This shallow-cycle pattern compresses the usable voltage window over time and causes the charge indicator to drift — the clipper reads full when the cell is already partially degraded. The battery hasn't failed suddenly; capacity has eroded gradually across hundreds of partial cycles. Replacing the cell and returning to fuller discharge cycles before recharging resets this pattern from the start.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor speed dropping before the low-battery indicator activates\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe ChroMini Pro's motor draws a short current spike each time the blade engages resistance — thick or dense hair amplifies this. An aged Ni-MH cell can't sustain voltage under that load spike, so blade speed sags noticeably while the indicator still shows charge remaining. This is voltage sag under motor load, not BMS cutoff. The indicator measures resting voltage, not load voltage, so the two diverge as the cell ages. Fitting a fresh 180AAH restores the cell's internal resistance to spec and eliminates the sag.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416126029914,"sku":"BWCS-MCH180SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416126062682,"sku":"BWCS-MCH180SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416126095450,"sku":"BWCS-MCH180SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MCH180SL-1.webp?v=1779760313","url":"https:\/\/batteryweb.com\/products\/moser-chromini-pro-type-1591b-replacement-battery-12v-1800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
