Chemistry: Lithium Ion
Power [W-h]:  (AA: 2.25W-h) (AAA: 0.675W-h) (9V: 0.675 W-h) (D: 7.5W-h)
Voltage: (AA,AAA,D: 1.5V) (9V: 9V)
Capacity: (AA: 1560mAh) (AAA: 450mAh) (9V: 450mAh) (D: 5000mAh)
Charge Time: (AA: Under 2 hours) (AAA: Under 1 Hour) (9V: Under 3 Hours) (D: Under 5 Hours) Depending on charger specifications.
Cycle Rating:  1000+ Cycles
Charging Cable: 1 USB to 4 Micro USB, 1 USB to 2 Micro USB
Charge State Indicator: Red Green LED
Protection Circuit: Integrated safety circuit protects battery and device
Over-Heat Protection: Operating at max output the battery will not overheat, this is part of the protection circuit.
Other Safety Protections: Protects against Overload, Leakage, Short Circuit, Over Voltage, & High Temperature
Certifications: IEC 62133, CE, FCC, PSE, UN38.3, RoHS, REACH
Operating Temperature Rage: -20c -> 60c, (-4F-> 140F)
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 a control circuit, vs an alkaline or NiMh battery, where the cell discharges directly into the circuit (no control circuit). The battery life in dormant mode depends partly on the environment. High ambient temperatures, and higher humidity, increases the internal drain. But in normal circumstances a battery installed in a device, like a door lock, will last ~12 months.

quick and simple

Good, but could be much better

Pale batteries are the best rechargeable lithium batteries I’ve tried and for that I give them 4 stars. However, they don’t last as long as alkaline batteries, which isn’t a hard thing to overcome considering the energy density of lithium vs. alkaline. The 9 volt Pale batteries seem to be the worst as it runs low quickly. There also seems to be a slow drain on the batteries even when there is no load on them. When I need a battery that is going to last as long as possible I still use alkalines or non-rechargeable lithiums.

I’m grateful to have my Pale batteries, and again, they are the best rechargeables I’ve tried and I own a lot of them and save money with them in the long run.. I just think the technology has a lot of room to grow, especially given the high price tag. I look forward to their next generation.

Recharge Batts

Good batteries. Lighter for the same number and charge holds well. Doesn't do as well as regular batts in cold temps. Still using around house, more to come.

Bye-bye single use batteries

These are great batteries. My wife and I are so thrilled to have re-chargeable batteries that are simple to use and look and perform just like the ones we buy at Costco.

awesome kit with every size needed

Plug these babies in until they glow green and you're off!!!!! Amazing product and so glad to dump the need to buy AA batteries every other week for the gamer kids' wireless controllers!!!! It's nice to have the other sizes on hand (I never buy C or D or those rectangular ones until I need them.) Just have to charge them up for a couple hours and I'll be good to go for whatever we need. This is the future!
