Battery life will vary depending on battery type and your playing style. 

We recommend using AA batteries designed for high-current devices. Our favorite is the Panasonic Eneloop Pro 2550mAh rechargeable. Duracell and Energizer are good alkaline options. 

On average, the estimated battery life using alkaline batteries is 7 hours.

On average, the estimated battery life using high capacity rechargeable batteries is around 8 hours. 

Please Note:

Never mix batteries by type, brand or age in your ToneWoodAmp.

Alkaline cells tend to leak when a low current battery is mixed with a new battery. Leaking batteries will result in corrosion and may potentially cause serious damage to your ToneWoodAmp.
