BATTERY BRANDS RANKED FROM WORST TO BEST

11. XTAR

XTAR is a lesser-known brand you won’t see much on major battery review sites. They mostly focus on Li-ion rechargeable cells and tend to advertise higher-than-average capacities. On Amazon, you’ll see models rated at 3,300 mAh or even 4,150 mAh. These batteries are often more expensive than top names like Panasonic Eneloop or Energizer, but that’s somewhat justified by their larger capacity.

That said, XTAR batteries aren’t easy to evaluate. Independent testing is limited to a few models, and long-term performance data is lacking. Early tests suggest they perform well—for example, maintaining a steady 1.5V output until dropping to 1.1V to trigger low-battery warnings in devices. Thanks to their high capacity, they also last longer between charges compared to 2,500 mAh Ni-MH batteries.

However, testers have noted that these batteries generate a lot of electrical noise, which could interfere with devices like radios. They’re better suited for game controllers or similar devices where interference isn’t an issue.

Ultimately, XTAR’s lack of long-term reliability data and limited visibility on expert review platforms keep it from being a top pick. It’s not necessarily bad—just unproven.
