It fits the WP826, WP822, WP833, and WP612, among others. All share the same voltage rail, connector, and charge-acceptance profile from the base station.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWP826 \/ WP822 \/ WP833 \/ WP612 platform fit:\u003c\/strong\u003e\n    These handsets run the same 3.6V single-cell Ni-MH circuit with a shared connector pinout. The base station charges via the same contact arrangement across all models, so one pack covers the full range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and discharge on WP826 hardware. The BMS accepted charge normally from the base station contacts, and the handset's charge indicator cleared without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Ni-MH cordless packs:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before first use. Ni-MH cells ship in a partially discharged state — a slow, uninterrupted first charge lets them reach rated 1200mAh capacity. Skipping this step causes the first few cycles to run short.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charge light not activating on a fresh Ni-MH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eZTE base stations check the incoming cell voltage before starting a charge cycle. A new Ni-MH pack that has sat in storage can drop to 3.0V or below — low enough that the base interprets it as a fault rather than a depleted cell. The fix is to briefly power the handset on and off, which draws just enough current to shift the BMS out of its low-voltage hold state. After that, reseat the handset firmly in the base — the charge contact must make clean connection on all three pins for the indicator to activate.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time noticeably shorter than the original battery for the first few uses\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells don't deliver full capacity straight out of the box. The electrodes need three to five complete charge-discharge cycles before the chemical structure stabilises and capacity reaches the rated 1200mAh. If talk time improves cycle by cycle, the pack is conditioning normally — not faulty. To accelerate this, use the handset until the low-battery alert sounds, return it to the base for a full uninterrupted charge, and repeat. By cycle five, capacity should be at or near the 4.32Wh rated figure.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339911004250,"sku":"BWCS-ZTP826CL-1","price":13.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339911037018,"sku":"BWCS-ZTP826CL-2","price":14.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339911069786,"sku":"BWCS-ZTP826CL-3","price":15.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZTP826CL-1.webp?v=1778366945","url":"https:\/\/batteryweb.com\/products\/zte-wp826-replacement-battery-36v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
