Due to electrochemical reactions, batteries will continuously lose capacity during storage. Our unique POWER LOCK technology effectively reduces self-discharge rate, thus guarantees a longer shelf life of three years for DURATA batteries, doubling that of low-grade batteries.
(see picture A, illustrating the case of D size battery)
With the introduction of POWER LOCK technology, DURATA EXTRA HEAVY DUTY batteries are up to 160% longer lasting.(see picture B, illustrating the case of D size battery)
The POWER LOCK technology effectively resists against the impact and avoids deformation of the batteries during long-distance transportation. And during normal discharge, it ensures superior leak-proof performance of the batteries.
No leakage or deformation even at the temperature of 50℃.
