Mr Positive is a responsible retailer who adheres to the NZ consumer guarantees act. If you have any questions regarding our warranty and returns policy, please contact us. If you would like to lodge a warranty claim. Log into your account, within the Account Summary page, to find a section labelled "Resolution Centre", or contact us using the contact form on our contact page.

Any warranty process begins from the day the item is received by either Mr Positive or one of our nominated repair agents. Please ensure you return the faulty item to Mr Positive within a reasonable timeframe. Leaving something for 3-6 months before you send it in may mean that your warranty has lapsed. We can only begin the warranty process after we have received the faulty item.

Please note:
The warranty process begins only after we receive the faulty unit. Once the item has been received, the warranty process will take a minimum of 7 business days.
In the event there is no fault found with the returned item, Mr Positive and or Mr Positive Repair Agents will charge an inspection fee of $40.

Battery Charger Warranty

Our battery chargers and power supplies carry a minimum 12 month warranty. Some models and brands carry up to 36-month warranty. We list warranty details and terms for every product on the warranty tab of the product page.

Warranty will be void if the product has been used incorrectly, such as, with higher voltage or current than specified, damage due to heat, or if the charger has been damaged due to impact. Do not open your charger or power supply as this will also void your warranty.

Lead Acid Battery Warranty

Our Lead Acid Battery range is sourced from a reputable local New Zealand supplier and is covered by manufacturer warranty. Depending on the model, this warranty period is between 1-5 years. You can find more detail about warranty for any Mr Positive product on the warranty tab of the product page.

All lead acid batteries need to be returned to Mr Positive before the warranty process can begin. This is the same policy for any other product we currently carry. You can either drop it off to our Auckland showroom or ship it to us using an appropriate DG classified courier such as Mainfreight's Chemcouriers division.
Please try and return your faulty lead acid battery to Mr Positive in a reasonable timeframe. Leaving it 3-6 months before you finally get around to sending it in may mean that your warranty could have lapsed in this time.

Warranty will be void if the battery has been used in a manner that it is not specifically designed for. For example:

The Lead Acid battery has been;
Discharged past its recommended discharge state.
Charged with a charger that is not designed to charge that specific type of battery.
Charged at a higher current than specified in product data sheets.
Placed under a much larger current than designed for, or specified in the batteries data sheet.
Incorrectly fitted, particularly in 24v systems.

Lead Acid Batteries are a delicate product that require special care and specific charging practices. Never fully discharge a lead acid battery that is not designed for deep cycle use and never use a "standby" lead acid battery for large currents (such as engine starting). Simple common sense must be adhered to or your warranty will be void. If you require assistance choosing the right battery, please feel free to contact us and one of our experts will recommend a model that is not only the best option for your needs now, but also the future.

Lipo Battery Warranty

Lipo batteries are the preferred choice of hobby battery world over. They provide huge energy (current and power), can be charged extremely fast (up to 5 times their capacity in some instances), weigh considerably less than other battery chemistries and offer the ability for perfect balance charging of each cell. The downside of this great energy-to-weight ratio is that the lipo battery has very delicate chemistry. The batteries must be charged with a lipo charger, not used past their discharge voltage threshold and stored correctly. Lipo batteries provide a huge amount of energy in a short period of time, however, this means that their operating voltage range is small.

If your lipo battery has failed during normal use, it will be covered by warranty. Warranty will be void if the battery has been used beyond its recommended rating, used incorrectly or in a manner other than what it is designed for. For example:

The Lipo battery has been;
Charged without a lipo charger.
Charged beyond its fully charged voltage, or with a higher current than specified by the manufacturer.
Discharged past its safe threshold of 3.1v per cell.
Discharged at a higher current than its manufacturer specified discharge rating (C rating).
Damaged due to impact or a crash.
Short circuited or shows any visible signs of heat.

When a lipo battery has been used incorrectly or placed under great stress, it will show clear physical characteristics. The battery packaging (hardcase or soft case) will be loose which is a sign of cell expansion. Lipo cells expand drastically when they are incorrectly charged or put under huge stress.

It is important to follow some basic guidelines, not only to ensure your battery lasts for its lifespan, but also for your own safety. If you have any questions, please feel free to contact one of our experts or read our Introduction to Lipo Batteries and Lipo Safety Guide.

All our lipo batteries are stored at manufacturer recommended storage voltage. The voltage of each cell is tested before they are packaged for shipping to ensure they are in perfect working order before they leave Mr Positive's warehouse.
