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.

Great Big Power with lots of options

I’ve been searching for a D battery that could power my battery operated motion lights. The Pale Blue D batteries were perfect. The ability to charge via micro USB or USB C was the perfect fit. An added bonus was the lighter form factor of the lithium battery vs. standard single use batteries. They are the last D batteries I’ll need to buy for sure.

Great batteries

I tried the Pale Blue D USB rechargeable batteries as I was looking for a battery I could recharge from a device I already owned. They recharge via a USB connection and charge in a reasonable time and run well. I have not yet gone through a full charge but the performance has been just as good as any "throw away" battery. The batteries even come with a cable that allows recharging multiple batteries at once.

Full 1.5v all the way

Love these batteries. Full 1.5v and they don't leak. Quick to charge too.

Love these batteries!

The charge holds for a long time and they recharge much faster than I expected. I love that I'm not using disposables anymore!
