Fisher Impulse AQ 49Wh Lithium-Ion Rechargeable Battery Pack with Charger

Description

Extend your detecting time with the Fisher Impulse AQ 49Wh Lithium-Ion Rechargeable Battery Pack with Charger.

Designed exclusively for the Fisher Impulse AQ, this lightweight lithium-ion battery provides approximately 5.5 to 6 hours of runtime while weighing just 13.3 ounces.

Compared with the standard NiMH battery system, the 49Wh lithium-ion pack provides significantly longer operating time, making it a practical upgrade for longer beach, surf, and shoreline detecting sessions.

A compatible charger is included and can fully recharge the battery pack in approximately 5 hours.

Designed Specifically for the Fisher Impulse AQ

This battery pack is designed exclusively for the:

Fisher Impulse AQ Metal Detector

First Texas lists the 49Wh lithium-ion battery directly in its official Impulse AQ parts and accessories catalog.

Because the Impulse AQ uses a specialized power system, this battery should not be treated as a universal Fisher rechargeable battery.

49 Watt-Hour Lithium-Ion Power

The battery uses modern lithium-ion technology with a total capacity of:

49 Watt-Hours

This provides substantially more usable runtime than the standard Impulse AQ NiMH battery configuration.

5.5 to 6 Hours of Runtime

First Texas rates the 49Wh battery pack for approximately:

5.5 to 6 hours of operating time

That makes it well suited for:

• Longer beach hunts

• Surf detecting

• Tide-cycle hunting

• Extended shoreline searches

• Travel

• Backup power

Actual runtime can vary depending on detector settings, battery condition, temperature, and operating conditions.

Lightweight 13.3 oz Design

Despite the increased runtime, the 49Wh battery weighs only:

13.3 ounces

That makes it the lighter of the two lithium-ion Impulse AQ battery options currently offered by Fisher.

For detectorists who want longer runtime without moving to the heavier 98Wh battery, the 49Wh pack provides a useful middle ground.

Charger Included

First Texas states that the lithium-ion battery pack includes the appropriate charger.

This is an important distinction from some other replacement batteries where the charger is sold separately.

The included charger can fully recharge the battery in approximately:

5 hours

NiMH vs. 49Wh Lithium-Ion

The 49Wh lithium-ion battery is a significant runtime upgrade from the standard Impulse AQ NiMH system.

The 49Wh battery is ideal for users who want longer detecting time while keeping battery weight relatively low.

Ideal as an Upgrade or Spare

This battery can be used as:

• A runtime upgrade from the original NiMH pack

• A replacement lithium-ion battery

• A spare charged battery for longer hunts

• A travel backup

• A secondary power source for demanding detecting sessions

Keeping a spare charged battery can help minimize downtime in the field.

• 1 × Compatible Battery Charger

BATTERY PACK AND CHARGER ONLY.

Fisher Impulse AQ detector, power cable, search coil, headphones, and other accessories are not included unless specifically stated with the offer.

Why Choose the Fisher 49Wh Lithium-Ion Battery?

The standard Impulse AQ NiMH battery provides approximately 3.5 hours of runtime. For serious beach and surf hunters, that can be limiting during longer sessions.

The Fisher 49Wh Lithium-Ion Battery Pack extends runtime to approximately 5.5 to 6 hours while weighing only 13.3 ounces.

That makes it a strong upgrade for detectorists who want more time in the field without moving to the larger 98Wh battery.

With an included charger, approximately 5-hour recharge time, and direct Impulse AQ compatibility, it is a complete manufacturer-designed power upgrade for the detector.
