Step-by-Step Solution
Verify Battery Type
Check your battery is genuine iRobot. Unofficial batteries often trigger Error 5. Look for iRobot logo and authentic part number on battery label.
Deep Clean Contacts

$11.99Reset Charging System
Remove battery. Hold Clean button 15 seconds with battery out. This resets internal charging circuits. Reinstall battery and try charging.
Check Battery Age
Lithium batteries last 2-3 years typically. If battery is old and showing Error 5, replacement likely needed. Check purchase date.
Try Direct Charging
Some Roombas can charge via USB or direct plug. Try alternative charging method to isolate if issue is dock or internal charging.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If drain continues after replacing batteries, check the event history — a stuck-open sensor or rapid polling loop burns through batteries in days.
Error 5 with non-iRobot batteries is common. The charging system checks battery authenticity and may reject third-party batteries.
Battery-related failures are almost always flagged too late — the device degrades silently for days before the app catches up to what's actually happening.
