Not much drop in price for larger orders. It was still competitive with other on the internet.

OSI Batteries had the UPS batteries that I needed to keep my unit running like it was new. These batteries were direct replacements for the batteries that came in my UPS when I bought it. I purchased two and both were well packaged and in excellent condition when they arrived. Brand new and value priced, there is no place else to buy your batteries except OSI Batteries.
After browsing different websites, OSI Batteries had a good value on the batteries that I needed.
These batteries had the flame retardant cases, which is what is recommended for UPS usage. Also, the batteries were direct replacements, meaning same amperage per hour, high discharge rate, and terminals that fit my UPS.

Why Trust Verified Reviews?
Verified Reviews are real, authentic reviews collected from actual paying customers, using Shopper Approved's Verified Review Platform. When reviews are Verified by Shopper Approved, you know that you can trust them to make better buying decisions.
Unverified Reviews on the other hand, are reviews collected by Open Review platforms that allow anyone to leave a review, without any validation or proof of purchase. Unfortunately, most reviews you read online are Unverified Reviews, and can't be trusted.
As a consumer, here's how you can tell the difference:
Verified Reviews from Verified Review Platforms like Shopper Approved, have much higher review counts and higher overall Star ratings, because they attempt to collect reviews from every single paying customer.
Unverified Reviews from Open Review Platforms, tend to have much lower review counts and more negative Star ratings, because people with bad experiences are primarily those who leave reviews. This often creates a misleading, inaccurate portrayal of a companies true reputation.
So, when searching for Verified Reviews, look for the name you know you can trust. Shopper Approved.
