Lithium Battery Pack
5
years · LiFePO4 pack
The longest coverage on the vehicle, and the part most people worry about. Exclusions apply — see the battery section below.
Warranty & Service
Covered, and kept moving.
Everything on this page comes straight from the NIU GT Limited Warranty Terms and Conditions and the owner's manual. The full legal text is one click away — this is the readable version.
What's covered, and for how long.
NIU Power Inc. warrants every new NIU GT low-speed vehicle sold by NIU or an authorized NIU dealer in the United States to be free from defects in material and workmanship under normal use. Coverage starts on the original retail purchase date.
Chassis & Frame
3
years
The structure the whole vehicle is built on, against defects in material and workmanship.
Controller
3
years
The brain between the battery and the motor gets a year more than the rest of the driveline.
Everything Else
2
years · standard period
Motor, charger, transaxle, brakes, steering, body and all other original components. Windshield is one year.
This warranty applies to the original retail purchaser only and is non-transferable unless applicable law requires otherwise. Full legal text: NIU GT Limited Warranty Terms and Conditions (PDF).

Four steps, one phone call.
Warranty service runs through authorized NIU dealers and service centers. Start there — not with a parts order.
01
Contact a dealer
Call an authorized NIU dealer or service center. Any of them can open the case — it doesn't have to be the one that sold you the vehicle.
02
Show the paperwork
Proof of purchase and the vehicle identification number. Both are needed before a claim can be assessed, so keep the bill of sale somewhere you'll find it.
03
Let them inspect it
NIU or its authorized representative inspects the vehicle. NIU may also ask for photographs, diagnostic reports or the defective parts themselves before approving.
04
Repair or replace
NIU repairs the component or replaces it with a new or remanufactured one, at its option. Parts replaced under warranty become NIU property and must be returned on request.
Five things that void it completely
- The vehicle has been modified beyond factory specifications
- Non-OEM parts or accessories were installed and contributed to the failure
- Required maintenance has not been performed
- The VIN has been altered or removed
- The vehicle has been used in a way inconsistent with the owner's manual
Modifying vehicle speed, weight distribution, battery systems, suspension or safety systems can cause property damage, serious injury or death — and will void this warranty.
Not much to do. Do it anyway.
Straight from the maintenance schedule in the owner's manual. Skipping it isn't just wear and tear — "required maintenance has not been performed" is one of the conditions that voids the warranty outright.
| Interval | What gets checked | Who |
|---|---|---|
| Before every use | Tire pressure, tread depth and surface damage · body and chassis · bolts, nuts, screws and rivets · reversing buzzer · loose or broken connections · battery secured and terminals clean · brake pedal firm, stopping inside 14 ft (4.3 m) · parking brake locks and releases · steering free play | Owner |
| Monthly 20 rounds · 20 hours · 100 miles |
Clean and lubricate the pedal control area · check all wiring for insulation cracks and wear points | Owner |
| Every 6 months 125 rounds · 125 hours · 600 miles |
Shock absorbers for oil leakage and damage · battery discharge test · lubricate chassis and moving parts | Dealer |
| Every year 250 rounds · 250 hours · 1,200 miles |
Rear axle bearing clearance · steering knuckle bushing and wheel alignment · wheel nut tightness and front wheel bearing clearance · battery terminal protector · transaxle oil level and leaks · pedal stop adjustment | Dealer |
| Every 2 years 500 rounds · 500 hours · 2,500 miles |
Change the transaxle oil | Dealer |
| Every 2 years 1,000 rounds · 1,000 hours · 5,000 miles |
Internal disc brake inspection, brake pads replaced if needed | Dealer |
Whichever comes first — rounds, hours or miles. Replace a tire once tread depth is down to 1 mm (0.04 in). If you're not comfortable with a job, it belongs at an authorized dealer.
Battery Care
Five years of coverage, on five simple rules.
The lithium pack has the longest warranty on the vehicle — and the longest exclusion list. Almost every excluded case comes down to letting the pack sit empty or charging it in the cold. Follow the rules from the owner's manual and none of it applies to you.
The rules that keep it covered
- Never charge below 0 °C (32 °F) — strictly forbidden
- Don't let the charge drop below 20%
- Use only the original charger for this pack
- Not used for over a week? Disconnect the battery from the vehicle
- In storage, give it a full charge at least every three months
The questions that actually come up.
General product questions live on the manuals and FAQ page. These are the warranty ones.
Does the warranty transfer if I sell the vehicle?
No. This warranty applies only to the original retail purchaser and is non-transferable, unless applicable law requires otherwise. A second owner buys the vehicle without the balance of the coverage.
What voids the warranty completely?
Five things: modification beyond factory specifications, non-OEM parts or accessories that contributed to a failure, required maintenance that wasn't performed, an altered or removed VIN, and use inconsistent with the owner's manual. Changes to speed, weight distribution, battery, suspension or safety systems are the ones that also carry a real safety warning.
Is the battery really covered for five years?
Yes — the LiFePO4 pack carries a five-year warranty against defects, the longest period on the vehicle. What it doesn't cover is damage you cause: over-discharge, long-term storage without charging, battery starvation from poor maintenance, physical impact, and any unauthorized modification of the battery system.
Can I use a third-party charger?
No. The manual is explicit: use only the original charger designed for this lithium pack. A non-approved charger counts as a non-NIU approved part, and any damage it causes sits outside the warranty. A genuine charger is a lot cheaper than a battery.
Who pays to get the vehicle to the dealer?
You do. Transportation to or from a dealer or service facility, travel expenses, loss of vehicle use, rental vehicles and towing charges are all outside the warranty unless NIU specifically authorizes them. Worth asking before you book a truck.
Does the warranty cover commercial and fleet use?
Yes, on a shorter schedule: one year on the vehicle, two years on core components (battery, controller, motor) and one month on wear items. This applies to rental fleets, resort operations, golf course fleets and commercial transportation services.
Do I have to have it serviced at a dealer?
Daily checks — tire pressure, brake feel, lights, cleaning — are the owner's job and affect nothing. The scheduled work is different: repairs by unauthorized service providers aren't covered, and required maintenance that wasn't performed voids the warranty. Keep the records.
What does NIU actually owe me on a valid claim?
Repair of the defective component, or replacement with a new or remanufactured one — at NIU's option. That's the sole remedy. Incidental and consequential damages, loss of use and loss of income are excluded to the maximum extent the law allows, and replaced parts become NIU property.
