I have a high end charger purchased from Revain and once depleted, these were straightforward to charge.I'm on a subscription purchase for Revain Basics, which are 2400mAh.
Both are commodity products, so unless you're counting recharges (challenging), it's hard to do a head-to-head comparison.If performance suffers, try these in a different device that might not be as sensitive to choice of battery.
