Mighty Max Battery ML15-12 12V 15Ah F2 Scooter Battery Replaces 14AH National C14A, C-14A - 3 Pack

I bought these for my Black and Decker electric lawn mower, which would no longer charge. Black and Decker replacement batteries are not available, but articles online revealed that 3 of these would fit in the plastic case of the original battery.Some people report that they had to modify the plastic, but mine slid right in.The mower is working quite well again - quite a relief that I didn't throw $100 down the drain!

It worked for a motor bike, that needed 3 of them

Replaced my super scooter 800 batteries. Fit well. Had to use new spade lugs to connect. No problem. Seems to charge ok. Used only once now and seem ok. Will see how long they last

I wanted to replace my batteries of my battery power lawn more and am glad I came across these babies. Although I had to make some slight adjustments in my battery housing to accommodate their slightly larger size of my originals, the increase in power was certainly welcomed.

Ok

These Mighty Max batteries have met my expectations. They are as good, or better than the original ones.

Works as stated

We have a electric lawn mower that still works well but the battery pack was no longer holding a charge, and the mower is no longer made so a replacement battery is not available. My husband did research on-line and learned the original battery internally was the same as this Mighty Max. He carefully measured and we took a chance that he would be able to replace the internal contents of our mower battery with these. Unfortunately, it didn't quite fit; this is not the manufacturer's fault of course as I don't think they suggest one should do this. He had to do some delicate filing of the plastic case of the original battery compartment, but he was finally able to fit it in. The mower is working quite well again -- we can mow the back and the front lawns on a single charge with power to spare. Hooray!
