How do I start a warranty claim?

Open a Technical Support ticket and fill out the form with your order info or proof of purchase. That gives our tech team what they need to diagnose the issue fast and move a warranty claim forward if it qualifies.

Step 1: Gather what you’ll need

• Original order number from DakotaLithium.com, or proof of purchase/receipt (dealer invoice, email receipt, screenshot of transaction)

• Battery model and voltage + amp-hour rating (example: 12V 100Ah)

• Charger info (brand, voltage + amps, and any LED/error behavior)

• If possible: multimeter readings and a few photos of your install and wiring

Step 2: Fill out the Technical Support form completely

Go here and select Technical support:

Fill in every field you can, including:

• Name, email, phone number, order number

• Battery voltage and amp-hour rating

• What device(s) you’re using it with (include year, make, model)

• Whether you have a multimeter

• Voltage reading of each battery before and after attempting a charge (isolated readings if it’s a bank)

• Charger voltage reading with the charger not connected to the battery

• Whether you’re using a Dakota Lithium charger

• Charger voltage and amp rating, plus what the LED does before and after connecting

• A clear description of the issue (what happened, when it started, what you’ve already tried)

Step 3: Add photos if you can

These speed everything up:

• Battery terminals and cable connections (close-up)

• Full install photo (wide shot)

• Charger label and LED/status lights

• Any error codes on charger, monitor, or device

A technician replies in the ticket thread, confirms troubleshooting, then explains next steps if we need to move into a warranty replacement or return process.
