## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Seems to be lasting just fine
  

*by A***R on Reviewed in the United States on April 18, 2024*

Purchased/installed this battery in early August 2021 in my 2000 Honda XR650R dirt bike with a Baja Designs lighting kit installed. Because of its small size the battery fits right under the seat. Its a low milage bike that I sometimes ride one day on the weekends, so use is infrequent and not often. During the cold Pennsylvania winters the bike gets stored in a barn with no use except for firing it up a couple times just to run gas through it (I don't really "winterize" it).  I have used a Battery tender on it just a few times successfully, just to keep the voltage up, but for the most part, I don't keep it on the charger, it just holds the charge on it's own. Therefore, I feel it is a fairly durable battery. As far as functionality is concerned, the lighting  kit includes a tail light/brake light, regulator, turn signals, horn and a high/low beam headlight (kick starter only bike).  The stator was re-wrapped so it does charge when being run. The lights and the bike run steady without any dimming.  Yesterday I power washed the bike and the light switch turned to the ON position by accident from the spray. I am unsure how long the lights remained on, but some hours later, I noticed that the switch was ON and the lights were out. I figured the battery was dead but placed it on the Battery Tender anyway and to my surprise, it took a full charge.  Hopefully the battery will continue to be as useful as it has been thus far.  It's pricey, but I think it's been worth it. I hope this overly long review is helpful for some folks.

    Small but power
  

*by S***P on Reviewed in the United States on August 4, 2013*

I needed a small battery pack that could also be charged off the bikes power system. I did not want to have to plug my bike in every night. This Trail Tech battery pack was one of the few I found that is able to charge off the bikes power. I have this coupled with the Trail Tech regulator/rectifier and they have been working great!

    Just a warning.
  

*by C***G on Reviewed in the United States on September 10, 2023*

Mine arrived dead, and refused to charge. I would also like to note that as the listing states there can be slight variations to what is shown in the picture. In my case it came with two double female bullet connectors so I would have had to cut one off and crimp a male negative or make an adapter. Also worth noting is that they used 18 AWG wire... You can kind of see that in the picture. The entirety of the rest of my bikes electrical is in 14 AWG wire so I feel like they skimped on the wire they used. For a $70 battery... I am in the process of returning the dead battery.
