Segway Navimow Battery Replacement: When and How to Do It

When It's the Battery, Not the Dock

Our dedicated Navimow charging guide covers a mower that won't charge at all, which is almost always a dock or contact issue. This guide is for the other case: the mower charges normally, shows a full charge indicator, and still can't finish a mowing cycle without draining and returning early.

---

Signs Your Battery Actually Needs Replacing

• The mower returns to the dock noticeably more often than it used to, on the same mowing schedule
• It stops mid-cycle with a low-battery alert rather than completing its run and returning normally
• A full charge cycle no longer takes it anywhere near its original runtime

If the mower isn't charging at all rather than draining fast, check our dedicated Navimow charging guide first — a new battery won't fix a dock or contact fault.

Before You Start

Tools needed: A small Phillips or Torx screwdriver, depending on your specific model — check your manual to confirm. Have a genuine Segway replacement battery ready rather than a generic third-party pack.

Safety first: Power off the mower and disconnect it from the dock before starting. Never work on the battery compartment with the mower powered on.

Battery Replacement: i105N and i110N Models

How to Fix:

1. Power off the mower at the main switch
2. Open the battery compartment access panel per your model's manual
3. Disconnect the battery connector from the main circuit board
4. Remove the mounting screws holding the battery in place and lift it out
5. Install the new genuine Segway battery, reconnect the connector, and secure the mounting screws
6. Close the compartment and power the mower back on

Time: 15-25 minutes | Cost: $150-250 for a genuine replacement battery | Difficulty: Easy

Model notes: Both models use a similar compartment layout, but the RTK positioning module draws continuous power for GPS processing even during idle periods, so battery life and replacement intervals can differ somewhat from a simpler boundary-wire mower — confirm your exact model's battery part number before ordering.

Pro tip: Take a photo of the connector orientation before disconnecting it — a small detail that's easy to get wrong on reassembly.

Why Genuine Batteries Matter Here

Navimow's RTK positioning system runs continuously to maintain precise location, which is a different power profile than a purely mechanical boundary-wire mower. A mismatched or uncertified battery is a real safety and performance consideration in this kind of sensor-heavy, weather-exposed unit.

Extending Battery Life Before You Need a Replacement

• Keep the dock shaded rather than in direct sun
• Store the mower fully charged in a dry, frost-free location over winter, not partially depleted
• Clean the deck and wheels regularly — extra drag makes the motor and battery work harder than necessary
• Replace blades when they dull rather than letting the mower struggle through thick grass
• Keep the RTK reference station antenna clean, since poor signal can cause the mower to work harder re-establishing position, draining the battery faster

When DIY Won't Work - Repair vs Replace

If you've replaced the battery with a genuine part and the mower still shows the same symptoms — frequent returns, stopping mid-cycle — the fault is more likely in the charging circuit or control board than the battery itself.

Signs it's time for professional service:

• A brand-new genuine battery doesn't resolve the original symptoms at all
• The mower shows a battery communication error rather than a simple low-charge alert
• You're not comfortable with the disassembly involved

Cost comparison: A genuine battery runs $150-250 depending on model. Weigh that against the mower's overall age and how much of its runtime problem is genuinely battery-related versus a GPS/RTK signal issue driving inefficient mowing patterns.

Warranty check: If the mower is still within its original warranty period, a battery that's failed prematurely may be covered — check with official Segway support before purchasing a replacement yourself.

FAQ

How long should a Navimow battery actually last?

It varies with lawn size and usage, but the continuous RTK positioning draws more steady power than a simpler boundary-wire mower, so expect replacement intervals to reflect that.

Can I use a third-party battery instead of a genuine Segway one?

It's not recommended. Navimow's sensor-heavy power profile makes a correctly rated, genuine battery more important than on a purely mechanical mower.

Do I need to reprogram the mower after replacing the battery?

No — install the new battery and use the mower normally. Your saved zones and schedule aren't affected.

What tools do I need for a battery replacement?

A small Phillips or Torx screwdriver, depending on your specific model — check your manual to confirm.

My mower still returns to the dock often after a new battery. What's wrong?

Check the RTK reference station antenna next — poor signal can cause inefficient mowing patterns that drain even a healthy battery faster than expected.

Is battery replacement covered under warranty?

If the mower is still within its warranty period and the battery failed prematurely rather than through normal aging, it may be covered. Contact official Segway support before replacing it yourself if you think this applies.
