    • An effective little power house!
Size: 1 Pack
The Fulpower Model MH645 6V sealed maintenance-free lead acid battery was just what I needed. I have an old Honda Trail 70 scooter that needed a replacement battery. This battery fit the bill perfectly. The battery fits perfectly in the space under the seat as if it had been manufactured specifically for this application. The battery is made well and looks like the many other sealed lead acid batteries that are available. The battery case is solid and clearly has the battery specifications clearly marked on the side This battery arrived packed well with protective covers on the terminals. The measured voltage on the battery was 6.44 volts right out of the box, but I plan on putting this on a suitable charger to make sure the battery is at full potential when I install it. The size was absolutely perfect for this application, but I can see where this could be used in a number of other applications calling for this style of battery. The terminals on the battery are clearly marked for positive and negative, and came with plastic caps to prevent accidental shorting of the push on terminals. If I really had to grasp at straws to find something wrong with this, it would be that the terminals are slightly smaller than the ones on the original battery. Since this scooter does not have electric start and the battery only is used for the ignition and when the light is turned on, I'm not concerned with the connectors. After it was installed, the scooter starts, runs and charges just like the original equipment battery and I couldn't be happier with it. For the price, you can't beat this little power house and I defy you to find another with the same features for less! ... show more

    • Great replacement for KidTrax 6v ride on mower.
Size: 1 Pack
Look, recently my wife got taken on facebook marketplace with a "free" ride on mower for kids. "everything works!" is what they said. lies. 100% did not. so I saw this and took a shot. This works great. took a little finagling with the old battery, but the terminals are so easy to access and connect it was a breeze. It fit into the slot perfectly for the KidTrax ride on mower and there have been no issues with compatibility whatsoever. a lot of people tend to toss out old ride on toys because the batteries are expensive in the stores, but this one is affordable, easy to read to match volts and amps and fairly easy to install with a little knowledge and some basic electrical connectors. ... show more
