Lithium-ion Safety Warnings and Handling Precautions

• Never Puncture or Crush: Use only blunt, non-conductive prying tools. Puncturing the 3.8V replacement cell for iPhone can cause thermal runaway and fire.
• Keep Away from Heat: Never expose the battery to extreme temperatures, open flames, or direct, intense sunlight.
• Handle Gently: Do not bend, twist, or drop the battery during the unpacking or installation process.
• Inspect Before Use: Stop immediately if you notice any swelling, strange odors, or physical damage to the aftermarket Apple 12 Pro Max battery prior to installation.
• Recycle Responsibly: Never throw old batteries in the regular trash. Always dispose of them at a certified e-waste recycling center.

FAQs: Haisic iPhone 12ProMax Battery

Here are the most common questions we receive as a B2B iPhone battery manufacturer regarding our replacement cells:

• Does this battery trigger the “Unknown Part” warning in iOS?
  Yes. Like all aftermarket Apple 12 Pro Max battery replacements, installing the HS-iP12Pro Max battery pack directly will trigger the non-genuine part warning. To bypass this message and maintain battery health visibility, repair technicians need to spot-weld the original battery BMS board onto our replacement cell.
• What is the warranty period for bulk orders?
  As your dedicated OEM smartphone battery supplier, we back our manufacturing quality. We provide a solid 12-month warranty on all wholesale iPhone replacement parts, ensuring reliable performance for your repair shop or distribution business.
• How long does shipping take for a wholesale order?
  Delivery timelines depend on your location and the selected freight method. Air shipments typically arrive in 5 to 10 business days. For larger volume orders using sea freight, expect 20 to 30 days. We dispatch directly from our Shenzhen mobile battery factory, optimizing global logistics to keep your inventory fully stocked.
