SIAC, the touch free timing product from SPORTident, has a small battery inside it that needs to be replaced every 3 or so years. Events that use SIACs should also have a battery check available for participants to check the battery levels of their SIACs. If the battery check signals that your battery level is low then you should get the battery replaced or the touch free functionality may stop mid-race and you'll be left with contact electronic punching only. You may also like to get the battery replaced every 3 years even if the battery check is not yet signalling a low battery.
GKO offers a battery replacement service. You send us your SIAC's by the 1st of December or by the Monday of Queen's Birthday Weekend and I'll send you back the replacement as soon as it is ready. This was initially quoted to be 2 weeks, but our first batch took 6 weeks.
Consider combining your family's, friend's or club's SIAC replacements into one order to save shipping effort and cost. You may also leave your SIACs with me on the Monday of the Queens Birthday Weekend orienteering event.
SPORTident has information on the battery replacement here.
