For private EV sellers
Sell your EV with the battery proof buyers ask for
Buyers can’t see inside a used EV’s battery, so they assume the worst and offer less. ClearWatt gives you an independent EV Health Report that shows your battery’s real condition — ready to share on your listing or with a buyer.
One battery health test. One report. A faster, fairer sale.
Buy a battery health test
Battery health is the question every EV buyer wants answered
When someone buys a used electric car, their biggest worry is the one thing they can’t check: how much battery health is left. Without proof, that doubt turns into lower offers, longer conversations and listings that sit.
Buyers fear hidden degradation
Range and resale value both depend on battery health, and a buyer has no way to verify it from a photo or a test drive.
Doubt costs you money and time
Unanswered questions turn into cautious, lower offers and more back-and-forth before anyone commits.
Most private sellers can’t prove it
Manufacturer apps and dashboards don’t give an independent figure a buyer will take at face value.

An independent EV Health Report — proof you can hand straight to a buyer
ClearWatt assesses your battery from real driving and charging data, then produces a clear PDF you can attach to your listing or send to anyone who enquires. It’s independent of you and the manufacturer, so buyers can take it at face value.
