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.

Pale Blue Does It Right

I confess I have not used these D batteries yet, but I most certainly HAVE used their AA, AAA and 9-volt batteries, and they are terrific. I put two AAs in my beard trimmer, and they have been running strong and powerful for a ridiculously long amount of time! Have not yet had to recharge them once. And if they truly deliver as many charges as promised, I'll die before they do. Highly recommended.

Good product, unsatisfactory support

Ordered these D cells to replace a defective D cell in a prior order. When I notified their support department of the defective cell, they agreed to send a replacement. What I received as replacement was actually a pack of two AAA cells. A lot of good that did! Support would not respond to my follow up correspondence. Accordingly I had to order and pay for replacement D cells. Never again will I order from PaleBlueEarth.

Great Batteries

Easy to charge...

D Cell Batteries Good So Far

In general I like the D Cell batteries. They are easy to recharge and pretty convenient.
Some things could be improved.
1. The amount of time they work in my shower radio is very short compared to regular alkaline D Cells, Way less than 1/2 the time. I have to always watch for the low battery signal on th radio so that I can get them recharged right away otherwise it will just not turn on the next time, whereas regular D Cell will work for a while if I turn the volume down.
2. The little pop-up for the charging connections seems kind of cheap. It would be nice if they were just built in like the AA cells.

Hot Wheels Heaven!

My kids have been getting a lot of use out of the D batteries with the Hot Wheels tracks! Now they can play as long as they want!
