Mighty Max Battery 12V 5AH Battery for Razor E100 E125 E150 E175 Scooter - Not Compatible with Power Core E100-2 Pack

I have a mower that uses WORX WA3216 24v batteries. Those cost around $100, are getting hard to come by, and generally only last a season (I have been through 3 of them). These batteries can replace the two batteries in that battery unit @ 1/4 the price. I did have to replace the battery connector ends from the case, as they were industrially soldered (I have 2 irons that could not get hot enough to de-solder them). Just google the WORX battery model number, and you will find a few videos with step by step instruction. WARNING: working with battery connections can be dangerous, so if you have no experience with electronics, I would not recommend this as a DIY project.

I've reordered these 3 times now and very pleases with quality, power, and speed at which they ship the battery's. I been repairing scooters and customers are telling me the get a little bit more run time on these battery's than the originals ever did. I will be continuing to use theses for all battery replacements.

very good, came charged, worked perfectly, not easy to install

As other reviewers state, you have to desolder the old connectors to hook this up. Took about an hour to do 2 scooters/4 batteries. Weight and size match the originals. They both hold a charge and put out equivalent power.

This product was defective and can’t return

Fixed up my E100 but i had to solder them on so at least I didn't have to buy the wiring harness. Not a bad price for a fix up. I had trouble getting batteries back into the scooter so i recommend taking pictures when removing the old ones including their position and how the connections are made. There are some good videos on line about how to diagnose and repair razor scooters.

Install was not too bad, but I had to: 1) Desolder the wiring harness from the existing batteries 2) Aquire and crimp on 4 terminals on the harness wiring 3) Used hot glue to ensure that the terminals would remain in place and be "water tight" or at least water resistant. If you can use a soldering iron and have a crimping tool, the total time to install is about 30 minutes. As for function of the batteries, my daughter is happily scooting up and down the street.

*** updating my review*** changing to 5 stars based upon customer service- they seller was quick to respond to my email and has refunded my payment. Original review- Amazon will not let me return these- they do not fit the E100 scooter, they are too wide! Item advertised to fit E100 scooter. I emailed the 3rd party seller and they need to give me a refund or replacement item that will work. If they do I will update my review!
