3.7V 2400mAh Replacement Battery for Garmin 010-11599-00 010-11654-03 361-00053-00 361-00053-04

Quick take

This 3.7V 2400mAh Li-ion replacement battery is built for select Garmin Montana GPS models, including the 600 and 650 families. If your goal is to refresh a battery that no longer lasts, it can be a reasonable aftermarket option, but review evidence is mixed around real-world runtime and whether the battery powers on reliably for every compatible unit.

Pros and cons

Pros

  • Designed for specific Garmin Montana models, with listed compatibility and part numbers.
  • Li-ion 3.7V battery rated at 2400mAh (8.88Wh).
  • Includes multiple protection features claims (over-charge, over-discharge, over-current, short-circuit).

Cons

  • Buyer feedback is mixed, including reports of shorter runtime versus the original battery.
  • Some customers report compatibility or power-on issues even when they expected the fit.
  • Quality outcomes may vary, so it is a smarter buy if your return process is straightforward.

What buyers think

Reviewed productBuy on Amazon

Buyer-review evidence for this replacement battery is limited in volume, but it shows two recurring themes. One group reports the battery works as expected after installation. Another group describes performance that falls short of expectations, including reduced runtime that requires daily charging, and in some cases the GPS failing to turn on after charging.

Because the feedback includes both working and non-working outcomes, the safest takeaway is that compatibility checking matters, and there is some risk that the unit you receive may not behave like the original battery in every Garmin Montana variant.

Pros and cons in plain terms

When this replacement battery makes sense

  • You want an aftermarket replacement for a compatible Garmin Montana model.
  • Your main problem is battery age, not damage to the GPS itself.
  • You are comfortable troubleshooting (for example, confirming the battery is seated correctly and fully charging it before first use).

Who should avoid it or proceed carefully

  • You need guaranteed power-on behavior immediately and do not have an easy path to return.
  • You are replacing a battery in a model with close-but-not-identical fit, where a similar-looking unit may still be incompatible.
  • You rely on maximum runtime and cannot handle the possibility of shorter endurance than your original battery.

Price and availability

It is an in-stock aftermarket battery option in the GPS battery category. If you are comparing alternatives, the deciding factors are less about marketing and more about matching the voltage/capacity and your Garmin model variant, plus whether your expectations for runtime are realistic for a replacement battery.

Alternatives to consider (based on your goal)

  • If reliability is your top priority: consider sticking to original manufacturer batteries for your exact device model, especially if you have had issues with aftermarket parts in the past.
  • If you want to reduce the risk of a mismatch: choose a seller or category where you can confirm fit and return easily, since review evidence includes both working and non-working outcomes.
  • If runtime matters most: compare batteries by capacity (mAh), but also plan for the possibility that real-world endurance can vary by how the battery performs over time.

Verdict

Reviewed productBuy on Amazon

The 3.7V 2400mAh replacement battery can be a practical way to revive supported Garmin Montana GPS units, and some buyers report it performs correctly. However, mixed review evidence (including complaints about reduced runtime and, for some, power-on problems) means it is best for shoppers who double-check compatibility and can handle a replacement if the first battery does not work as expected.
