D-Cell USB Rechargeable Smart Batteries - 2-Pack

It's time to re-think rechargeable batteries!!!

Superior Performance & Reliability with Fast Charging
With advanced lithium-ion rechargeable technology, Pale Blue batteries charge 5x faster than conventional Ni-MH (Nickel-Metal Hydride) rechargeables. These D-Cell batteries can be fully charged in only about 3-1/2 hours (compared to 4-8 hours for Ni-MH batteries).
Historically, most rechargeable batteries, were Ni-MH chemistry. However, long recharge times, poor performance, and short service-life prevented them from becoming mainstream.
Pale Blue's Li-Ion chemistry and smart circuitry resolves all these issues.

Stop Buying Disposable Batteries
Don't throw cash away on disposable batteries. A single Pale Blue rechargeable lithium-ion battery will replace over 1000 alkaline disposables – saving resources and eliminating unnecessary waste, while saving you a ton of money!

Fast Charging Lithium-Ion Battery
Charges in just 3-1/2 hours. 1000+ charge cycles.

Convenient Micro USB Charge Port
Just plug any Micro USB cable into the battery, or use the included cable to charge up to two batteries at once.
You can charge at home or on the go.

Built-In LED Charging Indicator
Pale Blue Batteries let you know when they are fully charged.

On-Board Smart Technology Provides Safe Charging
No overheating. No leakage. No more batteries ruining expensive electronic devices!

Extremely Low Self-Discharge: The dormant/self-discharge characteristics of Pale Blue batteries are very low. This is one of the advantages of a lithium-ion battery with an internal control circuit vs. an alkaline or NiMH battery, where the cell discharges directly into the device (with no control circuit). Although high ambient temperatures, and high humidity, can increase the internal drain, in normal circumstances a Pale Blue battery installed in a device, like a door lock, will last about 12 months before needing to be re-charged.
