Vault Zenith Spare Battery Pack - 2 x 18650 Lithium-Ion Cells with 2-Bay USB Charger
The Vault Zenith Spare Battery Pack (Vault_Zenith_Battery) is a pair of 18650 lithium-ion cells with a 2-bay USB charger, made for the Vault Zenith slimline push-pull smart lock.
The Zenith runs on a rechargeable 7.4V lithium battery made up of 18650 cells, and it ships with one set of cells and a USB-C charging cable. A second, charged pair means that when the lock warns of a low battery you can swap the cells straight away and recharge the flat pair afterwards, instead of waiting on the door while it charges. See the Zenith's battery and backup power section for how the lock is powered.
Usually ships next business day.

Frequently Asked Questions
It is the same 18650 lithium-ion cell format the Vault Zenith ships with - a pair of cells and a USB-C charging cable. Keep it as a charged spare set so the lock is never out of action while a flat pair recharges.
When the lock warns you the battery is low - the warning shows at the lock and in the Vault app. Open the battery box on the inside panel, swap in the charged pair matching the + and - markings, and put the flat pair on the charger. More in the Zenith battery section.
You can still get in. The Zenith has a 5V Micro USB backup input on the outside panel - a phone power bank powers the lock long enough to unlock it - and a mechanical key override. See what to do when the battery dies.
Yes, other 3.7V lithium-ion and IMR cells such as 21700 and 26650. Never put NiMH, NiCd or alkaline AA or AAA batteries in it - it charges to 4.2V, which those batteries cannot take.

Important Notes
Where a Vault product carries an Ingress Protection (IP) rating, that rating is stated on the individual product listing, packaging or technical documentation. Unless stated otherwise in writing, the IP rating applies only to the external-facing side of the lock - not to the internal assembly, handle, battery compartment, electronics, cables or connectors. The internal side must be installed in a dry, sheltered position. An IP rating describes water resistance, not waterproofing: the lock must not be submerged, pressure washed, or exposed beyond its stated rating, and all seals, gaskets and covers must be correctly fitted and undamaged.
Vault's manufacturer policy applies a warranty assessment holding fee, which is refundable if the fault is found to be covered under warranty. If a product is assessed as outside warranty or damaged by an excluded cause, a discounted replacement may be offered. We will confirm any applicable fees and options with you before any assessment proceeds.
This warranty is provided in addition to your rights under the Australian Consumer Law (ACL). Our goods come with guarantees that cannot be excluded under the ACL. You are entitled to a replacement or refund for a major failure, and to have goods repaired or replaced if they fail to be of acceptable quality and the failure does not amount to a major failure.
