  • Lighter replacement for camping lantern battery
Size: 6V 4.5Ah
Battery in camping lantern wasn't charging anymore. Concerned primarily with getting a replacement battery with dimensions same as the old battery as the placement of battery in the lantern is a tight fit; a few extra millimiters will not allow the battery to sit properly or allow the cover to be screwed back on. Overall, this battery is a good value product. It charged quickly and retained the charge. It is also so much lighter than the old battery! ... show more

  • TOBBI 6-Volt Car Back Running.
Size: 6V 4.5Ah
This got our son’s TOBBI 6-Volt Kids Ride On Car Electric VW Beetle back up and running. We needed a charger specifically designed for this battery type, and once we had the right setup, everything worked as expected. The battery lasts longer than the old lead-acid one and supports more charging cycles with the newer technology. It’s been running the car well with no issues so far, and I will update this review if anything changes! ... show more

  • Does not hold a charge very long.
Size: 6V 4.5Ah
I bought this for my deer feeder to replace one of the old style heavy 6-volt batteries that had died after years of use. This battery while inexpensive, does not hold a charge very long compared to the old battery. The old one would last a couple of months or more before needing charge, this one is about a month. I am not too happy about it, but for the price, I chalked it up to you get what you pay for. I will be more selective next time. Overall, for the price it is not a bad battery, and it weighs just a few ounces. ... show more

  • REPLACEMENT BATTERIES
Size: 6V 4.5Ah-2 PACK
I bought a farm that had a TSC DEER FEEDER, However the battery was dead. I looked on the TSC website for a replacement. They wanted $40 for a replacement battery. I ended up with 2 batteries here on Amazon for half the price and they charged quickly and are doing a great job I highly recommend these batteries. Great purchase and great quality!! ... show more

  • New Battery DOA
Size: 6V 4.5Ah
I did not get a chance to install this battery until over a month after I purchased it, so I cannot return it. The battery came out of the original box dead, will not take a charge and fried my 7.5vdc charger. I have verified the correct charging voltage for this battery is 7.5vdc. I am an experienced technician and I do NOT recommend anyone purchase this battery. Totally dissatisfied. I give 1 star review because I can't give it NEGATIVE 5 STARS! ... show more

  • Average battery
Size: 6V 4.5Ah-2 PACK
Don't last as long as I would expect. I figured the lithium batteries would last much longer than the lead based battery. These were minimally better than the lead one that died before I bought these.

  • Great for Hog 20 Amp battery replacements!
Size: 6V 4.5Ah-2 PACK
These batteries work great as replacements for the old lead batteries that came standard with my old Pignose Hog 20 portable amplifier! Dimensionally, they fit perfectly and keep the amp fully powered for at least 7.5 hours! I would have tested them longer but why bother? They work great. The only issue has to do with re-charging the batteries. They have to be removed from the amp and charged individually using a specific device designed for these types of lithium batteries. Amazon recommended I use the ULTRAPOWER 4-Amp 14.6 Volt LiFePO4 Battery Charger,12.8 Volt LiPO Lithium Battery Charger and it worked great. Looking forward to playing my blues harmonica again through this amazing amp! ... show more
