Golf Pad has built-in rechargeable battery and uses standard Micro-USB connector for charging. Plug the cord into any USB charger or computer. Full charge may take from 1.5 to 5 hours depending on charger and battery state. The charging LED is orange while charging is in progress and green when the reader is fully charged. Internal circuit protection prevents over-charge, so it's safe to leave LINK on charger even after the battery is full.
Fully charged battery lasts two rounds of golf.
NOTE: complete battery discharge may significantly worsen battery capacity or render it non-operational. Please be sure to charge LINK before your first round and re-charge every time you finish playing. If you are storing a reader for an extended period of time (e.g. off-season), please fully charge before putting to storage and re-charge every 3 months if storing longer than that. Failure to do so may void your warranty.
