NewPower99 Battery Replacement Kit for Garmin Dezl 770LM with Video Instructions, Tools, and Long Life Battery
Quick take
This NewPower99 kit is built to replace the battery in a Garmin Dezl 770LM (and related 770LM/770 series variants) and comes with installation tools plus step-by-step video instructions. It is a good choice if you want a DIY-friendly bundle rather than hunting for compatible parts, but buyer feedback includes reports of support issues and at least one case where batteries did not work, so do not expect every purchase to be painless.
Pros and cons
Pros
- Designed for the Garmin Dezl 770LM family, aiming for direct fitment.
- Includes installation tools and step-by-step video instructions.
- Rechargeable lithium-ion battery included in the kit.
- Some buyers report the battery replacement restores GPS functionality.
Cons
- Battery life is not consistently proven in the available reviews (some buyers had limited time to evaluate it).
- Support-related complaints appear in the review set.
- One review mentions receiving multiple battery sizes, which may confuse buyers if they are expecting a single part.
What buyers think
Buyer-review evidence is mixed, but there are a few decision-relevant themes. Several reviews describe straightforward installation and a working replacement afterward, suggesting the kit is often compatible and usable for DIY battery swaps. Other feedback points to support dissatisfaction and cases where replacement batteries still did not work, which is a potential risk if you need troubleshooting help. Overall, the evidence supports the kit as a reasonable DIY option, while also indicating that outcomes and assistance experiences may vary.
What’s included in the kit
This bundle is meant to cover the “parts plus guidance” problem that comes with older GPS battery replacements. You get a rechargeable lithium-ion battery intended for the Garmin Dezl 770LM model line, plus the tools needed for installation. The kit also includes step-by-step video instructions to help you through the process.
Battery specs you should check before installing
Compatibility matters more than marketing terms for battery replacements. The battery in this kit is listed as lithium-ion, with a capacity shown as 750 mAh and a 3.7 V rating. If you are comparing this to another replacement option, double-check that your device model matches the Dezl 770LM/770LM-family fitment the kit targets.
Pros for the right buyer
- You have a Garmin Dezl 770LM that no longer holds a charge and you want a dedicated replacement kit with installation help.
- You prefer a guided DIY approach (video instructions plus included tools), rather than piecing together parts from multiple sources.
- You want a practical backup option if you keep a travel GPS and want a spare battery on hand.
Who should consider other options
- You need flawless support and fast troubleshooting if something does not work, because the review set includes support-related complaints.
- You want long-term battery performance proven by strong evidence, since the available feedback does not give a consistent, detailed picture of runtime after replacement.
- You are not comfortable opening electronics or following careful install steps, because this kit assumes you will do the replacement yourself.
Pros and cons of this kit versus “just a battery”
Why the kit can be easier
Battery replacements often fail for reasons that are not the battery itself, such as using the wrong tools, rushing the install, or missing a specific connector step. A kit that includes tools and video guidance can reduce that friction.
When a bare battery might be better
If you already own the right tools and know the install steps from prior work, you may prefer a simpler, battery-only purchase to avoid extra parts. However, you should still confirm your device compatibility carefully.
Installation caveat to plan for
Some buyers report receiving more than one battery size included in the package. That can be helpful if the kit covers multiple closely related variants, but it also means you should verify which battery matches your exact device before installation. If you are unsure, it is worth comparing your model number before you open the unit.

Verdict
The NewPower99 Battery Replacement Kit for the Garmin Dezl 770LM is a solid buy for DIY shoppers who want the right-looking fit plus tools and video instructions in one package. The main caution is uncertainty around long-term battery-life evidence and mixed support experiences in the review set, so it is best approached as a practical replacement kit rather than a guaranteed smooth outcome.
