How to choose
Battery Chemistry Compatibility
When selecting power for your DeWalt DC390, identify whether your tool requires Ni-MH or Ni-Cad chemistry. The Shentec 18V replacement battery is specifically noted for Ni-MH compatibility, while chargers like the DC9310 are designed to support both Ni-Cad and Ni-MH battery types. Always verify that the battery chemistry matches your existing tool requirements to ensure proper function and avoid compatibility issues. Mixing technologies can impact performance and charging safety, so checking your tool's manual or current battery label before purchasing a replacement is a critical first step for any workshop owner.
Capacity and Runtime
Capacity, measured in milliampere-hours (mAh) or ampere-hours (Ah), determines how long your tool runs between charges. Options like the Shentec 18V battery offer 5000mAh, while other replacement packs provide 4500mAh or 4.5Ah. Higher capacity generally translates to longer runtimes, which is beneficial for heavy-duty tasks with the DC390. If you are working on extended projects, prioritize higher mAh ratings to minimize downtime. Consider purchasing multi-pack bundles, such as the 2-pack options available for 18V XRP replacements, to keep a fresh battery ready while the other is on the charger.
Charger Versatility
A dedicated charger is essential for maintaining your 18V tool fleet. The DC9310 replacement charger is engineered to work with a range of Ni-Cad and Ni-MH batteries, including models like DC9096 and DW9099. Some kits, such as the 3-piece BatPower set, offer a comprehensive solution by including both high-capacity batteries and a fast charger compatible with the 20V MAX system. Assess whether you need a standalone charger to revive your existing battery collection or a bundled kit that modernizes your power source with high-capacity lithium alternatives.
System Migration
Users looking to upgrade their power platform may consider the BatPower replacement kit, which provides 6.5Ah XR high-capacity lithium batteries and a DCB118 fast charger compatible with the DeWalt 20V MAX system. This is a significant departure from the standard 18V Ni-MH or Ni-Cad setups. If your goal is to transition your tools to more modern lithium-ion technology, look for kits that include both the necessary batteries and the specialized charger required to support that chemistry, as standard 18V chargers will not be compatible with newer lithium cells.
Tool Compatibility Lists
Before finalizing your purchase, cross-reference your specific tool model number against the manufacturer’s compatibility list. Products like the Shentec 18V replacement explicitly list compatibility with the DC390, DC385, and various other legacy tools like the DW938 and DC988. Do not assume universal fitment for all 18V batteries; check the product name for specific model numbers to ensure the physical interface matches your tool. Proper alignment prevents damage to the battery terminal and ensures a secure connection during operation, which is vital for maintaining the tool's performance and safety.
Frequently asked questions
Can I use a 20V MAX battery with my 18V DC390 tool?
The BatPower kit is compatible with the DeWalt 20V MAX system and includes a fast charger. However, standard 18V tools like the DC390 are typically designed for Ni-Cad or Ni-MH batteries. Unless you have a specific adapter, 20V lithium batteries are not natively compatible with 18V tools. Always check that your chosen battery chemistry and voltage match the tool's original specifications to avoid equipment damage.
What is the difference between the DC9310 and other chargers?
The DC9310 is a replacement charger specifically designed to charge DeWalt 18V Ni-Cad and Ni-MH batteries, such as the DC9096, DC9098, and DW9099. It serves as a dedicated power source for legacy battery technologies. In contrast, other chargers in the market, such as the DCB118 included in some kits, are designed for the 20V MAX lithium-ion system. Ensure you select the charger that matches the chemistry of your battery packs.
Are the 4500mAh replacement batteries compatible with all 18V tools?
While the 4500mAh replacement batteries are compatible with the DC9096, DC9098, and DW9099 series, compatibility is defined by the tool's interface, not just the battery capacity. These batteries are designed for 18V XRP systems. You should verify that your specific tool model is listed in the product description, such as the DW9098 or DE9095 series, to ensure a proper fit and electrical connection.
How do I know which battery chemistry my tool uses?
You can determine your battery chemistry by checking the label on your existing battery packs or looking at the tool's manual. The products listed here specify if they are intended for Ni-MH, Ni-Cad, or Lithium-ion systems. For example, the Shentec replacement is noted for Ni-MH. Matching the chemistry is essential, as charging a battery with an incompatible charger can lead to poor performance or potential safety hazards.
What should I do if my battery won't hold a charge?
If your battery is no longer holding a charge, it may have reached the end of its cycle life. Replacement options like the 2-pack 4500mAh DC9096 or the 5000mAh Shentec battery provide new power sources for your 18V tools. Ensure that your charger, such as the DC9310, is functioning correctly. If both the battery and charger are aged, purchasing a bundled kit that includes both can be a more efficient solution.
Bottom line
For owners of the legacy DeWalt DC390 looking to maintain their existing 18V platform, the Shentec 18V 5000mAh replacement battery stands out for its high capacity and broad compatibility with legacy tools like the DC385 and DW938. When paired with the DC9310 charger, which supports both Ni-Cad and Ni-MH chemistries, this setup provides a reliable path for keeping older tools functional. Alternatively, the 2-pack 4500mAh DC9096 replacement sets offer excellent value for those needing multiple batteries for longer jobs. These options prioritize direct, drop-in compatibility for the 18V XRP system, ensuring that your existing tool fleet remains powered without requiring an expensive or complex migration to a different voltage platform.
Deciding between these options depends on your long-term tool strategy. If you intend to stay with your current 18V tools, select the high-capacity battery packs like the 5000mAh Shentec or the 4500mAh 2-pack bundles to maximize runtime. Conversely, if you are planning to upgrade your entire collection to modern standards, the BatPower 20V MAX kit is the superior choice, as it provides both the lithium-ion power and the necessary fast charger to modernize your workshop. Choose based on whether you want to preserve your legacy equipment or transition to the current DeWalt 20V MAX ecosystem.
