  • Nice Lithium Battery
Size: 1 Count (Pack of 1)
Emergency light batteries only last a couple years. It's nice to now have a lithium option. Not sure yet about the longevity, but hopefully it will be at least as long as the lead acid ones.

  • great replacement
Size: 6V 4.5Ah-2 PACK
Bought this to replace the battery in my son's Marshall Firetruck riding toy. I was worried at first because this is not the typical battery you just plug into the toy but my husband installed it easily. It was ready to ride when it came out the box and lasted awhile. We've only had it hooked up for a few days but seems to last, we will see how it holds up over time. Worked with the charger that came with the truck. ... show more

  • Only lasted 2 months…. Do Not Buy!
Size: 1 Count (Pack of 1)
Bought this battery in August, it came charged. Connected it to our keypad and it’s dead and won’t take a charge. Only lasted 2 months. Save your money!

  • Works as Intended
Size: 1 Count (Pack of 1)
While I just received the battery and can't verify anything about longevity, the charging of the battery performed as expected and light went off when fully charged. Charge was almost 7 volts.

  • Out of box failure - replaced!!!
Size: 6V 4.5Ah-2 PACK
I ordered two. One failed immediately and wouldn't charge. I'll change this rating if anything good starts happening. Update: The seller sent a replacement for the out-of-box failure. Five star for that! I'm still in the process of assessing the battery performance, so I am giving it a 3 star at this point. ... show more
