Frequently Asked Questions

Just like with a cellphone, the charge time depends on the battery charge level when you start charging the device. If the battery is almost full when charging starts, it may only take a few minutes to top off. If the battery is completely flat, it will take less than 2 hours to fully charge.

The QuantiCheck has a typical battery life of 8+ hours per charge. This will allow for many seal checks to be performed. If you are using the QuantiCheck regularly, OHD would recommend that you charge it at least once each week.
