The Latch M's 6 AA batteries should last 12 months under normal usage. Managing them is simple. Just follow these steps.
Reading battery life
View device battery life using the Latch Manager or Manager App.
Battery life is refreshed every time a device is updated. If a device hasn't been updated for a while, the reported battery life could be out-out-date. If a battery hasn't been read for more than a month, it'll be reported as 'unknown', and you'll need to update the device to get a reading.
- Remove the Latch M's back cover
- Replace the 6 AA batteries with AA non-rechargeable alkaline batteries
- Important: Replace ALL 6 AA batteries with new batteries of the same brand. Mixing and match new batteries will reduce battery life.
- Update the device (Important: failing to update the device after battery replacement can result in unreliable functionality). How do I update a device?
