Incredible!! Every ROWER needs to get these

Replace the D Batteries on your rowing machine now with these. They last longer and you'll never have to dispose of those bulky single use D Batteries again.

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.
