Lithium-ion cells promise a lightweight high-capacity power source, with absolutely no memory effect. This means no unexpected loss of charge over time or during extended use, a common attribute of nickel-cadmium cells. Unlike other rechargeables, Delkin Power batteries do not require fully charging or periodic discharging, and weakening currency will never be an issue. In contrast, similar nickel-based batteries lose an average of 1-5% of their charge per day, whether in use or storage. Advanced safety features and non-toxic metal manufacturing eliminate any possibility of overheating, short circuiting or further electrical hazard. Plus, this sustainable, recyclable Delkin battery has proven to have less of an impact on non-renewable natural resources by 23 times, global warming by 28 times and air pollution by 30 times in comparison to the average disposable.
