Easy Way to Check Battery Charge
This is a great accessory for people that already have a Battery Tender charging tail hooked up to their bike. Just plug this into the SAE connector on the tail and you'll see a digital readout of the charge level of your battery, along with colored LEDs indicating the battery's general charge level. It's simple, compact and inexpensive. Highly recommended.

Works well, easy to read.
The meter plugs to the battery side cable in place of the charger. It works well, easy to read. We bought it to use on several batteries, motorcycles and 4-wheeler. We have a Battery Tender Lithium Battery in a motorcycle and the package for this meter says "Not for use with Lithium batteries". This notice is not in the write-up on any websites that we are aware of. Don't know why it couldn't be used except that the lights would not give the proper indication for lithium battery levels.

Pretty nifty little thing for the price
I actually bought this on a whim when I was buying the Battery Tender USB adapter and I have to admit it's a pretty handy little tool. I have Battery Tender pigtails on both my bikes and it's really easy to just plug this into the pigtail and determine the standing charge on the battery. With two bikes in the stable sometimes one will sit for a fair amount of time and this way I know whether I need to top up the charge before I take that bike out within seconds.

Great Little Accessory
I got this after I added the SAE pigtail to the battery...Glad I did, this makes it very simple to check the status of my battery without pulling the seat off or trying to start the bike. I wish I'd thought of this one years ago...Thanks to Lemmy for your write-up on inexpensive upgrades that help improve the riding experience.

This little doo-dad works like a champ; is fairly inexpensive, and makes monitoring my battery fast and simple. What's not to like?

f800gs limited charging
I really needed to see what my power consumption was and this delivered. I hooked it up an ran my aux lights heated grips and heated jacket and high beams.I took a reading with this and it showed i was in the green with all things running. Nice to know exactly what my power consumption is and quick reference to battery state of charge. Highly recommend

Simple, easy to use.
This is a very simple, easy to use voltage meter. You just plug it into the battery tender plug on your bike and it has a digital display of your battery's voltage. It's helpful when you want to know the "static" voltage of your battery as well as how low your battery voltage drops when starting your bike and when your bike is idling.

The only reason I did not give this 5 stars is because this meter is not as convenient to read as one that's mounted to the instrument cluster.

Great product. Makes it really easy to monitor the health of my battery on occasions when I don't get out on by bike as often as I might like.

Simple and quick way to check battery voltage
Not much to say about this device. It's really just a plug and play item to quickly check battery voltage. It works as advertised. Recommended.

To keep track of my Goldwing and other batteries so I'll know when I should turn on my charger so as to not have an under charged or over charged battery.

Good to quickly double check my bikes electrical load
Colby H on Oct 5, 2015
I was curious about the status of the battery when I took my bike out of storage. It had been sitting for about 11 months in a storage unit unplugged. I connected the battery to the bike and plugged this thing in and it lit up like a Christmas Tree! I was pleased to know that my battery was still good. One less thing to worry about. Great product!!!

The KLR does not have a charge indicator so this fills that need nicely.

Enables you easily monitor battery condition via a Battery Tender wiring harness (or a Gerbing harness if you buy the Gerbing SAE adapter) that you already have connected to your bike's battery.

I figured to be nice to have this in my tour pack as a good tool to see how my battery and or alternator is doing road side.

What are the dimensions of the unit? Is the unit waterproof? Backlit? Any way to neatly mount it permanently? I'm in the market for a small permanent voltmeter.
A shopper on Dec 24, 2013
BEST ANSWER: Overall length is 3". The meter part is 1 1/16" wide. Not back-lit.
No claims for waterproof. Clearly intended as a diagnostic tool, not a mounted gauge.
Pkg states "Not for use on Lithium batteries"
Need details on how this voltage meter works.
1] Do you check battery life before starting bike and what should light or digital meter indicate?
2] Do you check battery or charging system while bike is idling or higher RPM? What should light of meter indicate?
3] Do you check battery after stopping for proper charged level? What should the light or meter indicate?
No instructions on packaging how this meter works or understanding displays.
Thanking you in advance.
A shopper on May 10, 2014
BEST ANSWER: This is a digital voltage meter. The meter should read around 12 volts with the green light on without the engine running. If not, the battery has low voltage. The meter should read higher than 12 volts & green light on with the engine running, meaning it is charging the battery. If not your charging system is not working.
Will this work with new lithium ion battery?
A C on Feb 10, 2016
BEST ANSWER: Sorry, I used the Battery Tender Digital Volt Meter only on conventional batteries. This meter is wonderfully convenient, and will make my proposed study of motorcycle battery longevity possible. The study argues that because trickle charging is itself harmful to the battery, shorter charging periods, in the neighborhood of two hours just prior to riding, will keep the battery stronger. Incidently, not related to the study, I now believe motorcycle batteries should be replaced presumptively every two years, especially in warmer climates, and when rides are of short distance at lower speeds.
