These arrived with at least a partial charge. I couldn't determine if they had a partial or full charge though, so I charged them for eight hours.

They arrived with at least a partial charge. I have now way of telling if it is a partial or full charge , so I stuck them in the flashlights and charged them for eight hours.

I am purchasing two used LifeFitness cardio machines and picking them up this weekend. The current owner said he used to order his batteries on amazon. I prefer using 'other than amazon' when possible.

Google searched and your site was simple and to the point. The first review I saw was "they're the only place I can find this battery".

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.
