Catch dying laptop batteries before users do

Query battery health, current charge, charging status, and power source on any remote laptop in your domain. Identify batteries that have degraded below useful capacity — and plan replacements before a critical user is stranded mid-meeting or on the road.

Battery health & wear level

See each battery's design capacity vs current full-charge capacity. Identify batteries that have degraded past useful life and need replacement before they fail silently.

Wear levelCapacity drop

Real-time charge status

Current charge percentage, charging state (charging/discharging/AC), and estimated time remaining. Spot users running on fumes before their PC dies.

Live charge %AC/DC state

Power source visibility

Identify which laptops are on AC vs running on battery — useful during VPN sessions, video calls, or maintenance windows where unexpected shutdowns matter.

Fleet-wide battery audit

Scan all laptops in a domain or OU in one operation. Generate replacement budgets, identify warranty claims, and plan hardware refresh cycles based on real battery data.

Get going in under 60 seconds

From download to first result in five simple steps. No complex configuration, no firewall rules, no additional licensing.

  1. 1

    Install Free Windows Admin Tools

    Install on your admin workstation. No agent push to target laptops — the bundle runs entirely from your machine using authenticated domain credentials.

    Requirement: Two minutes, no license key — install only on the admin's workstation.
  2. 2

    Open Battery Monitor from the sidebar

    Click Battery in the sidebar of the unified console. The tool loads instantly alongside the other 14 utilities.

    Tip: Schedule a quarterly battery audit to catch degradation before users complain.
  3. 3

    Select your Windows domain

    Domain-joined computers populate from Active Directory automatically — laptops are auto-identified by chassis type, no CSV imports required.

    Filter: Sort by chassis type or hostname pattern to focus on laptops only.
  4. 4

    Pick a single laptop or a bulk group

    Pick one laptop for a spot check, or select entire departments and OUs for fleet-wide battery audits in a single operation.

    Best practice: Run quarterly across your 'Mobile Workforce' OU for replacement budgeting and warranty claims.
  5. 5

    Review results and plan replacements

    Sort by wear level to surface the worst batteries first. Export the report for warranty claims, procurement, and refresh cycle planning.

    Going further: For continuous device-health monitoring and proactive alerts, upgrade to Endpoint Central (free for 25 endpoints).

Built for real IT admin scenarios

Quarterly battery audits

Quarterly review of laptop battery health across your fleet. Identify batteries below 60-70% original capacity and plan replacements before failure disrupts users.

Pre-warranty expiration claims

Identify degraded batteries while laptops are still under warranty — claim replacements at no cost instead of buying them later out-of-pocket.

Mobile workforce support

For traveling sales, field service, or executive users, proactively swap degraded batteries before they leave town — prevent on-the-road dead-battery incidents.
