Quick Start Guide

Quick Start Guide



1. Charge overnight before first use.

The battery will go dormant when it goes for long periods without use, so the capacity will be lower than normal. It is easy to activate and restore the capacity after a full charge.

2.  Use the ORORO charger and cable ONLY. 

Different batteries are made with different specifications. You should only use ORORO chargers to charge ORORO batteries to prevent damage to the battery and other potential risks. 

3. Charge in a normal room temperature condition. 

The battery can be charged between 32 ℉ and 113 ℉. Don’t charge at extreme cold or hot temperatures, which would damage the capacity and the life span of the battery.

4. Remove the battery from the apparel before washing.

Our heated apparel is machine-washable, but not the battery. Remember to remove the battery from the apparel before you wash the apparel.
