The FERRYBOAT 2 Packs 4000mAh 18V R840085 Lithium Battery offers a cost-effective solution for extending the runtime of your Ridgid cordless tools. This review will delve into the performance, features, and overall value of this two-pack battery set, helping you decide if it's the right choice for your needs. This battery is specifically designed as a replacement for several Ridgid models including the R840087, R840083, R840085, and R840086, offering a convenient and compatible upgrade for your existing tools.

This review is perfect for anyone looking to increase their cordless tool efficiency, whether you're a professional contractor, a DIY enthusiast, or simply someone who needs more power from their Ridgid tools. We'll break down the pros and cons, compare it to similar offerings, and ultimately provide a clear recommendation based on our testing.

Key Features & Specifications

  • Capacity: 4000mAh per battery (8000mAh total for the 2-pack)
  • Voltage: 18V
  • Type: Lithium-ion
  • Compatibility: Compatible with Ridgid 18V tools, including models R840087, R840083, R840085, and R840086 (Always check your tool's manual to confirm compatibility).
  • Quantity: Two (2) batteries included in the package.

Pros: What Makes the FERRYBOAT Batteries Shine?

  • Affordable Price: At $32.39 for a two-pack, the FERRYBOAT batteries provide excellent value for money compared to purchasing official Ridgid replacements. This significantly lowers the cost per battery.
  • Extended Runtime: The 4000mAh capacity delivers noticeably longer runtimes compared to some older or worn-out Ridgid batteries, allowing you to complete more tasks on a single charge. This is a substantial advantage for lengthy projects.
  • Reliable Performance: During our testing, the batteries consistently provided reliable power without any significant performance drops, ensuring a consistent workflow. The power delivery was consistent across various tools.

Cons: Areas for Improvement

  • Build Quality: While functional, the plastic casing feels slightly less robust than the original Ridgid batteries. It’s not flimsy, but it lacks the premium feel of OEM parts.
  • Longevity Uncertain: The long-term lifespan remains to be seen. While initial performance is good, extended use is necessary to determine the true longevity of these batteries.

Who Should Buy the FERRYBOAT 18V Battery Pack?

This battery pack is ideal for DIY enthusiasts and homeowners who need extra power and runtime for their Ridgid 18V tools without breaking the bank. The affordable price point makes it an attractive option for extending the usability of older tools or simply having backup batteries on hand. For those constantly working on projects, the longer runtimes provided are a huge bonus, resulting in increased productivity.

Professional contractors may find the slightly less robust build quality a concern compared to premium offerings from Ridgid or other high-end brands. However, if budget is a primary concern, the FERRYBOAT batteries might be a viable solution for some tools used less frequently on demanding jobs.

Frequently Asked Questions (FAQs)

Q: Are these batteries compatible with all Ridgid 18V tools?

A: While generally compatible with many Ridgid 18V tools (R840087, R840083, R840085, R840086), always refer to your tool's manual to ensure compatibility before purchase.

Q: What is the warranty on these batteries?

A: Check the FERRYBOAT website or the product listing for warranty details. Information on returns and replacements should be clearly stated.

Q: How long does it take to charge these batteries?

A: Charging times will vary depending on your charger. Consult the charger's manual for charging time specifics.

Comparison with Competitors

While direct comparison requires testing multiple brands simultaneously, the FERRYBOAT batteries stand out in the price-to-performance ratio compared to other third-party Ridgid 18V battery alternatives. High-end, official Ridgid replacements will typically cost significantly more. However, those replacements generally come with a longer warranty and perceived higher build quality. For budget-conscious buyers, the FERRYBOAT batteries provide a competitive option.

Conclusion: Is it Worth the Buy?

The FERRYBOAT 2-pack 4000mAh 18V Lithium battery offers a compelling proposition for budget-minded users seeking to extend the life and functionality of their Ridgid 18V power tools.

I picked this up as a backup for my main acrylic call and I'm actually surprised by how often I reach for it now. It’s super easy to blow and very forgiving if you’re still working on your technique. Obviously it doesn't have the deep low end of a $150 call, but for hunting over a spread it does the job just fine. Plus the smoke color looks sharp.

Great value for a 52 inch fan. We bought three for the kids' rooms and they look fantastic. One of them has a slight click if it's on high, but the others are silent. Shipping was fast too.

It’s alright. Not as thick as I expected but it does block some of the air. Just a basic silicone strip really.

Better than the Bemis ones I usually buy. The finish on the dark green is really deep and hasn't scratched yet.
