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

On average, the estimated battery life using alkaline batteries (Energizer, Duracell) is six hours.

We recommend using AA batteries designed for high-current devices. 

Best: Tenavolts rechargeable batteries. 

Better: Panasonic Eneloop Pro 2450mAh. 

Good: Duracell and Energizer are good alkaline options. 

Tenavolts will provide 150% of the playing time that alkaline batteries will offer. In addition, there is no gradual power degradation or sensitivity to peaks that other batteries are prone to. As other AA batteries drain power, they fall below 1.5 volts. Tenavolts will provide a constant 1.5 volts. Recharge time is two hours.

Panasonic Eneloop Pro 2450 mAh lasts roughly 12 hours and are great for high-drain devices like cameras and portable recorders. Recharge time is roughly 7 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.
