Availability can ebb and flow, but you can usually find compatible replacement batteries right on this page. To narrow results quickly:

• Filter by platform: pick 18V or 20V Max to match your tools.
• Compare capacity (Ah): higher Ah generally offers longer runtime and may add weight.
• Check pack size: single, 2‑pack, or more for jobsite rotation.
• Review fulfillment: delivery or store pickup may be offered at checkout.
• Watch stock status: if one item is out, similar compatible options may be listed.

Before purchasing, confirm voltage and charger compatibility in the product details. If your preferred option isn’t available today, checking back or enabling availability notifications can help.

Color alone doesn’t determine performance. What matters are the specs on the label and listing:

• Voltage/platform: match 18V with 18V tools and 20V Max with 20V Max tools.
• Chemistry: lithium‑ion and Ni‑MH use different chargers—avoid mixing.
• Capacity (Ah): higher Ah can extend runtime, though weight may increase.
• Connector style: mounting rails and contacts must fit your tool line.
• Features: some packs include fuel gauges or reinforced housings.

If two packs differ only by casing color, they often function similarly, but it’s best to verify voltage, chemistry, and charger compatibility in the description—not the color.

Even when labels show the same nominal voltage (like “20V”), battery systems are typically brand‑specific. Differences in rails, contacts, and onboard electronics mean cross‑brand fit and communication aren’t guaranteed.

• Match the platform: use batteries designed for your tool family and charger.
• Check the listing: look for clear compatibility notes for your tool series.
• Adapters: third‑party adapters exist, but they can affect performance and safety, and aren’t always supported.

For reliable results, stick with batteries specified for your tools. If you’re unsure, compare the connection style and specs in the product images and details before buying.

You’re in the right place. This category brings together a wide range of compatible replacement batteries from multiple sellers.

• Browse and filter: refine by voltage (18V or 20V Max), capacity (Ah), and pack size.
• Compare details: confirm tool and charger compatibility in the description.
• Delivery options: shipping or store pickup choices may appear at checkout.
• Confidence checks: scan ratings, reviews, and Q&A for real‑world feedback.

Once you find a match, add it to cart and choose the fulfillment option that suits your schedule.

Capacity (amp‑hours, or Ah) affects runtime and weight, so pick based on how you work:

• Light tasks, short bursts: lower‑capacity packs keep tools lighter and recharge faster.
• Longer sessions: higher‑capacity packs can extend runtime between charges.
• Rotation strategy: a 2‑pack lets one charge while you keep working.
• Platform fit: always match the battery’s voltage (18V or 20V Max) and chemistry to your tools and charger.

Actual runtime varies with the tool and material, so reviewing capacity, weight, and compatibility in the listing can help you balance power and portability.
