Warranty & Compatibility

At Danube Supply, we understand that batteries power your essential devices—so reliability, safety, and compatibility are not optional. This page explains our warranty coverage and how we ensure product compatibility, helping you shop with complete confidence.


Warranty Coverage

We stand behind the quality of every product we sell.

What Our Warranty Includes

  • All batteries sold on DanubeSupply.com are covered by a limited warranty against manufacturing defects.

  • Warranty duration varies by product type and brand and is clearly mentioned on each product page.

  • The warranty covers issues related to defective materials or workmanship under normal use.

What Is Not Covered

The warranty does not cover:

  • Damage caused by improper installation, misuse, or incorrect charging

  • Wear and tear due to normal battery lifecycle

  • Physical damage, leakage due to mishandling, or exposure to extreme conditions

  • Use in incompatible or unsupported devices

Batteries are consumable products; performance naturally decreases over time depending on usage and charging habits.


Compatibility Assurance

Choosing the correct battery is critical for performance and safety. We take compatibility seriously.

How We Ensure Compatibility

  • Product listings include detailed specifications, such as voltage, capacity (mAh), chemistry, and model numbers

  • Laptop, camera, drone, and power tool batteries are listed with supported device models

  • Rechargeable cells and utility batteries are categorized clearly by size and type (AA, AAA, 18650, etc.)

Your Responsibility

Before placing an order, please:

  • Match the model number of your existing battery or device

  • Verify voltage, size, and connector type

  • Review the product description and compatibility notes carefully

If you are unsure, our support team is always available to assist before purchase.


Returns Related to Compatibility

  • Returns due to incorrect selection or compatibility issues are accepted only if the product is unused and in original packaging

  • Compatibility-related returns may be subject to restocking or shipping fees

  • We strongly recommend confirming compatibility prior to ordering to avoid delays


Safety & Usage Guidelines

For optimal performance and safety:

  • Use only approved chargers recommended for your battery type

  • Do not overcharge, short-circuit, or expose batteries to heat or moisture

  • Store batteries in a cool, dry place when not in use

Improper usage can affect battery life and void warranty coverage.
