Rachel Tiah – September 2, 2024

Can anyone tell me why it doesn’t have a battery indicator for the device itself? I’m curious about how to check the device’s battery life.

  Thank you for choosing our Ocean Reef Portable 9v battery tester (GSM)! I completely understand your concern about not having a battery indicator for the device itself. Unfortunately, this is a design choice made by the manufacturer to keep the device lightweight and compact. However, we do include a battery life indicator in the user manual that explains how to check the battery level. You can also consider incorporating an external battery tester to ensure the device’s battery is functioning correctly. We appreciate your feedback and would be happy to help you with any further questions!

What’s the maximum number of batteries it can test at the same time? I have a collection of batteries and I’m interested in knowing how many it can handle.

  Thank you for reaching out, Lucas. Our Ocean Reef Portable 9v battery tester (GSM) can test a single battery at a time, but it’s specifically designed to handle any 9v battery, regardless of its volume or size. For example, you can use it to test everything from small wristwatch batteries to large alkaline batteries.

The LED light on this device is really bright. However, it could be even brighter to make it more useful in low-light situations. It’s a minor complaint, though.
