Purchased an 8-year warranty battery. After 4 years, it failed within the warranty period.

Here's what I learned about Allied's warranty process: They do everything possible to blame you instead of honoring the warranty.

I had ONE single 51.2V 105Ah battery. When it failed, Allied insisted I replace it with FIVE separate batteries instead of a comparable single unit. That's not a solution—that's a complete redesign.

I sent multiple detailed technical questions about why a single replacement wasn't possible. Never answered. I followed up several times. Radio silence. I requested to speak with management. No one called. I waited over a month without a response while my equipment sat idle.

When they finally approved a warranty credit, they tried to charge me list price ($4,000) for five batteries. I own a golf cart with LED lights and a soundbar only. My cart has minimal power demands. When another vendor evaluated my setup, they confirmed my original single battery was completely appropriate and had no issues supporting my cart.

Allied claimed the battery was "undersized" to avoid their warranty obligation, but an independent evaluation proved them completely wrong. They approved a credit then refused to apply it when I went with another vendor.

Allied's strategy is clear: blame the customer, create an impractical solution, charge inflated prices, and make the warranty process so difficult that you give up. They care about the initial sale, not standing behind their products.

If you buy from Allied, understand that warranty support will be a nightmare. Better options exist.

Our battery began malfunctioning just days before the three-year warranty expired. Although Customer Service initially promised to resolve the issue or replace the unit, their policy changed once they received it. After we paid for shipping, they claimed the defect was our fault and demanded nearly $2,000 for a replacement. Allied does not stand behind its warranty commitments, and similar complaints are widespread (quick google search). I strongly advise looking at alternative brands that value integrity.

Little to no support despite being a dealer. Terrible customer service and cumbersome tech support/warranty process.
I’m still sitting with a customer’s battery for a year now waiting to return it for warranty repair/ replace. I had to give the customer a different battery ( my expense) to salvage the relationship.

I will never sell another one.

I have ZERO IDEA how they have such good reviews on their site. You can’t leave a review! They’re clearly cherry picking.

The only reason it’s a 2 Star Is that most of the batteries are still working. Don’t know what to do if they stop, fingers crossed I guess.

Terrible dealer support. Misleading, They Bombard You With TSR Request, Pictures Invoices, Bill Of Sales From Customers & Dealers. Warranties Can Take Up To 6-Weeks. They Don't Tread Printed Version The Responses On Emails You Give Them On The Reports. The Process Is Convoluted! I'm at point to tell my customers to contact them directly to complain. No Telephone Support... All Is Done By Email TSR. Don't Return Phone Calls. Since July 8th Trying To Return A Battery For Warranty....... 30-Years In The Golf Car Industry And Never Experienced Anything Like This. They Fired The Local Rep Who Took Care These Issues Promptly.
