I've had my SB-910 for a few years now although it's seldom been used (bought it new). Not long after I bought it, I left the batteries in it for a few weeks. Unfortunately the Duracell AA batteries leaked causing corrosion on both ends of the terminals. After cleaning the terminals, the flash wouldn't come on when using Duracells but did for the Eneloop AA batteries. So I used it as it was with Eneloops without any trouble.
A few months back while in my local camera store, I commented about the problem, and one of the employees told me to bring it in. He had some type of cleaner that worked really well. He cleaned the terminals at no charge, and it worked fine. That is until the last couple of weeks.
Suddenly it wasn't powering on. I fiddled with the connections (using a sync cord with a flash bracket). It came on. I thought that was the end of it. Then this morning it went haywire again. It powered on, took one shot, but wouldn't work for several shots after that.
The back of the flash display showed the following this morning for the first time ever (not my image. This photo is an SB-900 while mine is a 910. Same warning logo though.) Photo comes from this link: https://www.flickr.com/photos/61824374@N04/14656102688/
I fiddled with the connections and turned it on and off a few times before it finally came back to life. Not sure if the warning is due to the battery terminals, but I only fired the flash once before it stopped working. Unfortunately I didn't have the manual with me so I had no clue what the warning referenced. *sigh* I removed the Eneloop batteries, then after reinserting them, it powered back on. I hope by using it for the last few shots didn't damage it further. I'll be calling Nikon this week to see about getting it fixed. I have an SB-700 to use in the meantime so it won't be a problem. Hopefully it is something that can be fixed without costing too much.
I regret not contacting Duracell when this happened. Back then they used to promote their batteries saying they would cover damage to electronics if their batteries caused a problem. I just thought the problem was temporary and could be fixed by using the Eneloop batteries. Whether the issue is solely the terminals or something else, I have no idea.
