2-Pack 4500mAh Ni-Mh Replacement for Dewalt 18V Battery - Longer

In this review the focus is on a practical, budget-minded replacement battery kit for Dewalt 18V tools. The 2-pack includes two 4500mAh Ni-Mh replacement batteries and a DC9310-compatible charger, and the single biggest reason to consider it is the upgraded capacity that delivers noticeably longer runtime than older Ni-Cd packs. For tradespeople who need more run time between swaps and a charger that supports 7.2V to 18V Ni-Cd and Ni-Mh batteries, this kit is a straightforward, value-oriented option that works with a wide range of Dewalt 18V XRP models.

Key Features

• High capacity: The 4500mAh cells provide extended runtime for cordless reciprocating, circular or jig saws so users spend less time swapping batteries on site.
• Wide compatibility: Designed to replace DC9096/DC9098/DC9099 style packs, it fits many Dewalt 18V XRP tools and compatible chargers for flexible use.
• Included charger: The DC9310-style charger in the package supports 7.2V to 18V Ni-Cd and Ni-Mh batteries, enabling charging different legacy packs without needing another unit.
• Built-in protections: Over-charge, overheat, short-circuit and over-discharge protection help safeguard the pack and the tool during normal jobsite use.
• Diagnostic indicator: A single red light gives a simple charge status cue so users can tell charging progress at a glance.

Who It's For

This kit is best for DIYers and professionals who already own Dewalt 18V XRP tools and who prefer Ni-Mh replacement packs rather than buying new brand batteries. It suits people who value longer runtime and a spare charger to keep multiple batteries cycling on busy days.

It is not for users who require lithium technology or want the absolute lightest packs: the battery chemistry is Ni-Mh and the charger explicitly does not support lithium batteries. Buyers needing the latest lithium performance or lighter weight should look elsewhere.

Pros & Cons

Pros

• Higher 4500mAh capacity delivers longer working time compared with older Ni-Cd packs.
• Includes a DC9310-compatible charger so the kit is ready to use out of the box.
• Protection features and a cooling fin design help manage heat and extend pack life under typical use.

Cons

• Build quality and long-term reliability are mixed in user reports, so performance may vary between units.
• Not compatible with lithium chargers or lithium battery systems, limiting use if you plan to migrate to Li-ion tools.

Specifications

Our Verdict

The 2-Pack 4500mAh Ni-Mh replacement kit is a sensible value choice for users of Dewalt 18V XRP tools who need more runtime without investing in lithium systems.
