Kaadas digital locks require only 4 x 1.5V AA alkaline batteries. For models with 8 batteries compartment, we recommend using only 4 batteries at one time to reduce the probability of battery leakages. Use reliable battery brands to prevent battery leakage which could damage your lock. Digital lock damaged from battery leakage is not covered under warranty

Brands such as Panasonic Evolta and Duracell have proven to be more reliable as compared to other brands such as Ikea and GP where battery leakages were encountered before. In addition, please do not use:
  • Carbon-zinc type battery
  • Rechargeable batteries
  • Lithium batteries
  • Heavy duty or super heavy duty batteries
Batteries should be changed immediately once the low battery indicator lights up. In addition, we recommend customer to change all 4 batteries once every 6 months (even if there is no low battery indicator) as batteries with low power are more prone to battery leakages.
