Specs
Do you recharge the battery or throw it away after the 9 months? If rechargeable, how do you recharge it?
Answered by DESLOC Smart LockYes, the battery is rechargeable — there’s no need to throw it away after 9 months. K140 Plus uses a removable rechargeable battery with a Type-C charging port. You have two convenient charging options: you can remove the battery and recharge it separately, or keep it installed in the lock and connect a power bank directly to the battery, so the lock can continue working while charging. We also plan to offer spare batteries in the future, making it even easier to swap batteries without any downtime. The lock provides low-battery alerts in advance. If the battery is fully depleted while you’re outside, there is also an emergency charging port on the exterior side, which can be temporarily powered using a phone or power bank to unlock the door.
Does the smart lock provide alerts when the battery is low?
Yes, the smart lock includes low-battery alerts to notify you before the power runs low.
