As stated above, pls write to the email with your Masters invoice (Hopefully you still have it). Unfortunately they dont have any supplier in Australia and hence there is no point in reaching out to them if any of you were planning to do so. I was ping ponged between Kobalt and LOWE's (one of Kobalts main supplier in US). Just thought would also let you know that i had called the KOBALT US help line unsuccessfully as they only service North America and Canada. Your main responsibility would be to pack the products and drop it off at your nearest Australia Post outlet. They would also ask for your Home address and Bank account details to provide a refund if the product which you return is found faulty. Rebate form, proof of purchase and proof of status are required to receive an American Express Gift Card Rebate. I would like to receive informative and promotional emails from Briggs & Stratton. The Kobalt 24V Cordless Mower batteries and charger come with a 3-year warranty, and the mower itself with a 5-year warranty, so you’ll likely have lots of fun and relatively quiet lawn mowing in your future. The Woolies phone staff provided me with this email ID to which you should have to drop the INVOICE of the item you had bought You will get a mail from them with instructions about how to return the product (postage being paid by Masters/Woolies). Yes, enter me into the product registration sweepstakes. I called up WOOLIES to check on warranties on MASTERS product. I had asked 'AP' who has responded on this note about some basic trouble shooting, but once that didn't work i enquired around and this is the process i have gone through. Realised that Lithium ion batteries die if not used for a while. Just thought would let you all know that i was faced with a similar problem of the battery not working.
