Minelab Replaceable Alkaline Battery Pack for CTX 3030 and GPZ 7000

Forgot to charge your lithium-ion pack before a hunt? This Minelab replaceable alkaline battery pack gives you a field-ready backup that runs on 8 AA cells. Compatible with both the Minelab CTX 3030 and GPZ 7000 detectors, it drops into the same battery compartment as your rechargeable pack. The slim, lightweight design adds minimal bulk to your kit, and AA cells are available at any convenience store or gas station when you need them.

Why detectorists choose this battery pack

• Field backup when lithium runs low: swap in 8 AA cells without ending your hunt early.
• Dual-detector compatibility: fits both the Minelab CTX 3030 and GPZ 7000 Standard and Starter Pack models.
• Slim, lightweight design: carries easily in a pouch or pack without adding noticeable weight.
• Universal cell availability: AA batteries are sold everywhere, so you're never stranded without power.

How it works in the field

The pack slides into the same battery compartment that holds your detector's lithium-ion pack. When your rechargeable runs out mid-hunt, pull it and drop in the alkaline pack loaded with 8 fresh AA cells. Detectorists hunting remote sites or multi-day trips keep one of these in the truck as insurance.

Compatibility and use cases

This pack works with every CTX 3030 and GPZ 7000 configuration: Standard, Starter Pack, and any aftermarket coil setup. Detectorists hunting beaches, parks, and gold fields use it as a hot-swap solution when they forget to charge overnight or when a hunt runs longer than expected. The GPZ 7000 and CTX 3030 both benefit from the alkaline backup when lithium isn't an option. Keep the pack in your vehicle or gear bag, load it with name-brand AAs before you head out, and you'll never cut a hunt short because of a dead battery.

What detectorists say

The pack is a popular choice for detectorists who hunt off-grid or travel internationally where charging infrastructure is limited. It's also a backup for competition hunters who can't afford downtime during an event.
