Based on my experience, I would not recommend 4s Professional Car battery. The battery just died without any indication after 1.5 years. For warranty, you'll need to sent it to their office in Setia Alam. The warranty process are pretty manual. You'll need to produce original Invoice for Lazada or Shopee with Warranty Card in order to make a warranty claim. If you have misplaced the invoice, your warranty will not be entertained. Just imagine if you have just use it for few months and misplaced your invoice, you'll need to buy a new battery. They don't bother to check their system or assist to reissue invoices. Standard response, no invoice or warranty card, no warranty.
