The Danalock V3 locks are tested and certified with specific battery brands.
The use of other brands could void the warranty.
The lock uses 4x CR123A batteries, also known under these names:
- DL123A, CR17345, and more.
The Danalock V3 is only certified with Panasonic CR123A and Duracell CR123A batteries and we highly recommend only using these two brands.
Do not use rechargeable batteries!
We highly discourage using rechargeable batteries as many of them supply a higher voltage (up to 3.7 volts) than the normal 3.0 volts.
This can lead to an increased fire hazard.
The use of rechargeable batteries will void the warranty of the lock.
Never mix batteries
Mixing new and used (even partially used) batteries are associated with great danger and risk of fire.
Always replace all 4 batteries at the same time and always with 4 completely new batteries.
It is also not recommended to mix different brands or versions of the same brand.
