All TLJ contactless electronic door locks are self-contained and require no external wiring. Instead, they are powered by 4 x 1.5v AA batteries. Whilst any good quality AA batteries will work in the short term, they are designed for general use and are unlikely to give best results when used with our electronic locks.
For this reason, we’ve created superior TLJ Batteries for electronic locks. They have been designed specifically to power electronic lock sets and are manufactured to the highest industry standards. Independent tests of TLJ Batteries have shown that our unique construction ensures long term power delivery, with a gradual and predicable voltage drop off compared to the ‘cliff edge’ scenario of commercially available batteries. This gradual drop off and a series of built in low power warnings virtually eliminates any possibility of power failure.
