It is a compact flat-cell pack measuring 27.60 × 23.00 × 4.00mm, suited to small electronics where space is tightly constrained. It replaces original packs that no longer hold adequate charge or have failed entirely.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCompact cell format:\u003c\/strong\u003e\n    At 4.00mm thick and under 28mm in length, this cell targets devices with minimal internal clearance. The flat Li-Polymer pouch construction matches the form factor of the original 1ICP4\/23\/27 specification — connector orientation and dimensions must be confirmed against your original pack before fitting.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on the bench, monitoring the BMS cutoff thresholds and cell voltage under load. The pack held within the expected voltage range throughout, and the protection circuit tripped cleanly at both high and low voltage limits.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration:\u003c\/strong\u003e\n    If your device uses an integrated fuel gauge, run one full charge-discharge cycle immediately after swapping this pack. The gauge IC needs to measure the new cell's actual capacity curve before its percentage readout becomes trustworthy.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePack running at lower voltage than rated on first installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells ship at storage voltage — typically 3.70V to 3.80V — not at full charge. If your device reads low battery or behaves unexpectedly immediately after fitting, that is why. The cell has not been degraded; it simply has not been charged yet. Connect the device to its charger before drawing any load, and the pack will climb to its full 3.85V nominal range.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not accepting the pack after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome compact devices run a voltage-range check or a basic BMS handshake at power-on before accepting a new pack. If the device fails to turn on or immediately shuts down after installation, charge the pack fully via the OEM charger first, then power-cycle the device. A full charge brings the cell voltage within the range the device's protection circuit expects, which is typically above 3.80V, and clears most rejection faults on the first retry.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333473435738,"sku":"BWCS-CM051SL-1","price":17.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333473468506,"sku":"BWCS-CM051SL-2","price":19.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333473501274,"sku":"BWCS-CM051SL-3","price":21.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CM051SL-1.webp?v=1778212818","url":"https:\/\/batteryweb.com\/products\/custom-battery-pack-replacement-battery-385v-240mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
