Positive Grid Spark Battery - Portable Rechargeable Amp Power

Our review of the Positive Grid Spark Battery looks at whether this accessory is worth adding to a player who needs portable amp power. For gigging musicians, students, and practice players who want to perform without hunting for an outlet, the battery's single biggest benefit is freedom from cords: it delivers several hours of playtime depending on your Spark model and is designed to be easily swappable so sessions are not interrupted. This review focuses on real-world battery life, ease of use, and any limits a buyer should expect.

Key Features

• Model compatibility: Works with Spark LIVE, Spark 2, and Spark EDGE so players can choose the battery for multiple Positive Grid amps.
• Long playtime: Provides up to 12 hours of play for Spark 2, up to 10 hours for Spark EDGE, and up to 8 hours for Spark LIVE, letting users rehearse or busk without frequent recharging.
• Rechargeable convenience: Recharges while the amp is plugged in so you can jam and recharge at the same time without removing the battery.
• Portable power: Enables cord-free use so users can perform in locations without a power outlet or move around freely during practice and small gigs.
• Easily swappable: The battery is designed for quick swaps, minimizing downtime between sessions or when topping up charge.

Who It's For

The Positive Grid Spark Battery is best for guitarists and other musicians who use Spark LIVE, Spark 2, or Spark EDGE and need reliable portable power for rehearsals, small shows, street performances, or practice rooms. It particularly fits players who value battery life and portability over the limitations of plugged-in setups.

Players who rarely leave a powered stage or those who require extremely long continuous play beyond the quoted hours should consider staying with mains power or using larger external solutions, since this battery is optimized for convenience and moderate-duration portability rather than marathon gigs.

Cons
