SAE Voltage Indicator

I love plug & play, and this Battery Tender product is just that. I received it and just plugged it into a SAE fitting that was already on my DL1000 V-Strom and it immediately displayed the battery at 12.3 volts. I left it on the bike and it turned itself off in a few moments as advertised. I pushed the ON button and it displayed the reading again instantly.
I would recommend this this product without hesitation.

I got one for Christmas. Very handy carry tool. I finally figured out that it auto-OFFs after less than a minute. If you leave it plugged in it saves power and the green button turns it on for another reading when you are ready. I like it so well, I sent one to my son too.

This is a Battery Tender product, and it performs exactly as advertised. I mention that it is from Battery Tender because if you have a charging lead from B.T. already connected to your battery you can be sure it is already compatible with this little volt gauge. I suppose if you attached this gauge via a switched circuit or put a switch in line one could use some industrial double-sided tape and keep it on the bike (or whatever) and connected all the time all the time. Shame it doesn't have a switch.
