It slots into the handset battery compartment and powers both active calls and standby operation. No OEM part number is published for this model — fit is confirmed by voltage, chemistry, and physical dimensions (42.40 x 49.90 x 14.40mm).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eL000 handset compatibility:\u003c\/strong\u003e\n    The Sigma L000 runs a 3.6V NiMH cell with a three-contact terminal layout. Voltage and physical size must match exactly — a mismatched cell height prevents the battery door from seating, and a voltage mismatch will trigger the base station's charge circuit to reject the pack entirely.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the L000's charge circuit and confirmed the BMS accepted the NiMH chemistry without triggering a fault light. Charge termination fired correctly at full capacity, and the cell held voltage under RF transmit load without sagging below the handset's low-battery cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on the L000 base station:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before first use. NiMH cells ship partially discharged, and the L000's trickle-charge circuit needs a complete slow charge to bring the pack to rated capacity — a short charge will leave usable capacity on the table for the first several cycles.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than original battery after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells don't reach rated capacity on the first cycle — this is normal chemistry, not a fault. The L000's charge circuit runs a slow trickle charge, and a new pack typically needs three to five full charge-and-use cycles before it hits 1200mAh. Interrupting those early cycles short-charges the cell and locks in a false capacity ceiling. Run three full cycles — full charge, use until low-battery indicator triggers, return to base — and talk time will increase each time.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no-charge or error light after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe L000 base station reads pack voltage before starting the charge cycle. A NiMH cell that sat in storage can drop below the base's acceptance threshold — typically under 3.0V — and the base interprets this as a faulty or missing battery. Remove the handset, wait 10 seconds, and re-seat it firmly so all three contacts are fully engaged. If the error persists, a brief manual reset of the base station clears the charge controller and allows it to re-read the pack voltage from scratch.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340035063898,"sku":"BWCS-ADL930CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340035096666,"sku":"BWCS-ADL930CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340035129434,"sku":"BWCS-ADL930CL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ADL930CL-1.webp?v=1778367024","url":"https:\/\/batteryweb.com\/products\/sigma-l000-replacement-battery-36v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
