Toyota Highlander Premium would kill battery when not used for a week. This is because this model has way too many fancy accessories that are always working when the car is off. I have read about others who have a similar problem with this SUV. I don't drive it every day and we live on an island that is 5 x 7 miles and the car doesn't get a chance to charge up the battery with these short runs.

I bought this solar battery charger to keep the battery charged in my cargo trailer while it’s in storage. It had worked perfectly for 6 months but for no apparent reason just stopped charging recently. I emailed Sun Energise customer support and explained that it stopped working. They responded the next day and ask for a few pictures of the solar charger in different scenarios and connected to a different battery just to help them determine if it was indeed a product failure and not user error or being connected to a bad battery. Again they responded the next day to let me know that it is a product failure and they will be sending me a new one. I gave a 4 star review and not 5 only because it did fail, but I understand that sometimes things break. I would definitely give a 5 star for their customer service, they where fast to respond, courteous and understanding of my situation.
