It backs up the real-time clock and battery-backed RAM during mains power loss. Without a functional battery, the clock loses time and all stored employee attendance data the moment power drops.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e7000e and 7500e compatibility:\u003c\/strong\u003e\n    Both models share the same internal battery bay, connector pinout, and BMS handshake voltage. The 8.4V rail matches what the clock's backup circuit expects — a lower voltage cell will not trigger the backup latch correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through a simulated mains outage on the 7000e. The BMS engaged within seconds, the RTC kept running, and no data loss occurred on the employee record store.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePre-swap data export:\u003c\/strong\u003e\n    Export all employee enrollments and attendance records before removing the old battery. The 7000e stores this data in battery-backed RAM — full power removal erases it. Most firmware versions offer an export function under the system administration menu.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the 7000e loses all employee data after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 7000e holds employee enrollments and punch records in volatile RAM, kept alive by this battery. When the old battery dies mid-swap — or is simply removed — that RAM loses power and clears instantly. There is no secondary storage on most firmware revisions. The fix is to export data before any power is cut, not after.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eClock showing wrong time after every power outage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis symptom points to a depleted backup battery that can no longer hold the RTC running through a mains interruption. The real-time clock circuit draws a small but continuous current — a degraded Ni-MH cell drops below the minimum sustain voltage quickly under even that light load. Replace the battery and let it charge for at least 24 hours on mains power before testing. After a confirmed full charge cycle, the RTC should hold time through outages without reset.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426139111514,"sku":"BWCS-LTM750SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426139144282,"sku":"BWCS-LTM750SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426139177050,"sku":"BWCS-LTM750SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LTM750SL-1.webp?v=1779930385","url":"https:\/\/batteryweb.com\/products\/lathem-7000e-replacement-battery-84v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
