Battery came fully charged but I put it on the charge over night anyway. I connected it up to my new fish finder and ran it 24/7 for the next 7 days. Before connecting the fish finder I checked the voltage and it read 13.35 volts, 7 days later when I unplugged it I checked it again and it read 11.31 volts. I would say this was an excellent buy!!!

An excellent 12v to bring along camping. I do not have a depth finder, but use some 12v devices that have alligator clips. This is a very nice and compact unit that has outlasted our needs many times.
I really like that it included a charger, makes charging easy. I don't know what else to tell ya'll. Looks well made and it works great for all kinds of 12v applications.

I put this in a cheap tool box and added a few 12V car cigarette outlets for power, solar panel charge controller, speakers from an old set of self powered computer speakers and on off switch. made a portable power unit that can be used with a 12V to AC adapter to power just about anything. Used it when the power went out in San Diego. Also use it when golfing, fishing and car trips. It can power cells phones, camcorders, cameras etc. You can also plug a mp3 player into the speakers for tunes.

I like having a power supply in case the solar panels don't charge the battery all the way. Very cool!

Not much to say. It's a gel cell battery that works like you would expect. Got it for a Humminbird Piranhamax 170 to install in my kayak. Has enough capacity to run the sonar for a long time with full back light (12 hours and I still hadn't hit the 11 volt mark).

I could have probably went with a smaller battery, as this one seems almost like overkill.

If you want lots of capacity for a gray scale fish finder, you can't go wrong here.

Bought this as it included the charger and battery at a great price. Shipping was really fast and I received what I expected to get. Mounted it in a pelican 1120 dry box with a liquid tite fitting. Perfect!

Product was exactly as advertised, fast shipping. I had a problem with the charger about 2 months after I bought the first one, I emailed Humminbird to ask them how to handle it, the response I got back was, WE ARE SHIPPING A NEW CHARGER TO THE ADDRESS LISTED IN YOUR EMAIL, IF YOU WISH FOR IT TO GO TO A DIFFERENT ADDRESS PLEASE LET US KNOW. WE ARE SORRY FOR ANY INCONVENIENCE. They never asked the first question just sent the new charger immediately I received a few days later.

The only thing I can say is that this little gem of a battery is just what the kayak ordered. It powers my fishfinder perfectly. Yes, I am a gal for all hunting and sporting seasons.

I just bought this battery and charger a week or so ago and I had no intentions of using it for anything related to depth finders or whatever else may be compatible with this. I had to buy a new pump to blow up rafts for the boat and Kwik-Tek makes one that has alligator clips and I didn't want to actually hook it to the boat battery. I bought this and the pump and they connect perfectly and it is an awesome set up. It was hard to tell from the picture or the description what you could use this for. I was only able to tell from other reviews, but now I know and I am quite satisfied.

This is an excellent 12v sealed battery for portable depth finder setups. The charger included has auto charging shutoff which is nice.

This battery is perfect for my kayak depthfinder. Small enough to fit in the day hatch, light weight. However it's heavy enough that it doesn't slide around. Used it on 6 or 7 four hour plus fishing trips and it's still at 12.4 volts. I didn't even charge it when i received it. A+ product!
