Nikon EN-EL4, EN-EL4a Battery by Wasabi Power

A couple of years ago I purchased two ENEL4 batteries for my Nikon grip and recently one of the batteries just stopped working would not charge at all. As their warranty states and the instructions give I emailed Wasabi Power to as what could be done? I included images of the battery both in an out of the charger.
A couple of days later I received a reply with their apologies and a note that they were sending a replacement.

Thats customer service you just don’t see anymore. Thank you Wasabi Power I’ll be sure to recommend you services and products to everyone I know.

Cheers.

So far batteries are good showing 100%, and on 1 as new, even with some use. Will update after some use as time passes.
Very reasonably priced, with a 3 year warranty.

Everything worked perfect with overnight shipping. Received right on schedule. Thank you.

Holds a charge longer than original Nikon
