THIS IS FOR THE BLACK TIME MASTER PRO ONLY. This is a Lithium Ion Battery - Specs are: 1000mAh 3.7V / 3.7Wh - model number 102050, part number 201910 made in Korea and specifically for the Time Master Pro. Using another battery will void your 1 year warranty. The original battery in the Time Master Pro will recharge for at least one year (and often longer). A lithium ion battery stops charging automatically when it is fully charged so there is no risk of overcharging. Do NOT use any other charger than the charger provided with your Time Master Pro to avoid damaging your device. Please allow the battery to charge for at least 2 - 3 hours so you do not UNDER-charge the battery. The device will automatically shut off every 10 minutes for safety purposes. This does not mean your device is not working or is not charging. The Time Master Pro is only to be used for a MAXIMUM of 10 minutes. Using it longer is at your own risk - and must never be attempted until the device has time to cool and reset in between uses. Do not use more than 10 minutes - twice weekly. With continued use the sensation will lessen as the skin adjusts to Ultrasound. This does NOT mean your device is not charged or is not working.
