Titanium Power Enduro Low Self-Discharge Pre-Charged NIMH AA 2100mAh 4PCS + 1 Free battery case

Most rechargeable batteries arrive in the package with no charge in them. This means that users must spend hours charging the batteries before they can put them to use an inconvenience that makes them unfavorable to some consumers. Rechargeable batteries are packaged this way because they have an inherent self-discharge rate. Depending on how long a battery sits on a shelf, there may be no point in pre-charging a battery before it is put on sale as it might have zero power in it by the time it is

Power Enduro batteries utilize a new breakthrough in rechargeable battery technology that minimizes power loss from self-discharge. Power Enduro batteries only experience a self-discharge loss of approximately 1-2% per month, meaning that even if a battery sits on a shelf for a year, it will only lose at most 20% of its charge leaving plenty of power for a buyer to put in a device. 

Power Enduro batteries are essentially the environmentally friendly replacement to disposable single-use batteries. With Power Enduro batteries, users get the convenience they seek in being able to use the battery straight out of the package. At the same time, Power Enduro batteries help users comply with environmental regulations by eliminating the need for disposing of hazardous materials.
