I was worried as half of the batteries died and stopped accepting a charge from the Amazon charger

Half of the batteries died and wouldn't recharge after less than 5 charges

Half of them are dead and the rest discharged within 2 weeks not being use

About half remain useable, if you count those that only charge to about 80% according to several, different meters

Half died after the first couple recharges

To be honest, I think we lost about half of them

They work as they should

Works as it should.

The batteries work as they should

They seem to work as they should

These batteries work just as well and last just as long as it's big name competitor's, plain and simple
