The JET spare battery is a 14.4 V, 3.0 Ah Li-ion cell pack made for the JET 12–16 mm battery strapping tool. When your operation depends on a single battery, every charge cycle means the tool is out of action. Adding a second battery closes that gap.
Why One JET Spare Battery Is Not Enough
A battery strapping tool shipped with one battery ties your throughput to the charger. Every time the pack runs flat, the tool sits on the bench. On a loading dock or packing station, the pause stalls operators, queues pallets and pushes dispatch times back. The tool itself is ready; it is the empty battery that stops the work.

How a JET Spare Battery Keeps You Strapping
A second battery lets you rotate between two packs. While one charges, the other runs the tool. Swapping takes seconds: release the flat pack, slide in the charged one, continue strapping. Specifications of this battery:
- Voltage: 14.4 V
- Capacity: 3.0 Ah
- Chemistry: Li-ion
- Compatible tool: JET 12–16 mm battery strapping tool only
This 14.4 V, 3.0 Ah Li-ion pack is made for the JET 12–16 mm battery strapping tool. It charges with the charger supplied with your JET tool, so you need no additional charger to keep both packs in rotation.
Where a Spare Battery for the JET Fits and Where It Does Not
This battery is designed for the JET 12–16 mm battery strapping tool. It will not fit other tool models or brands. Before ordering, check the model printed on your tool’s label.
A second battery is worth considering when:
- One charge cycle does not cover your working period.
- Several operators share the same JET tool across shifts.
- Your battery has degraded and you need a 14.4 V, 3.0 Ah replacement for the JET tool.
What to Check Before You Order Your JET Spare Battery
This listing is for one Li-ion battery only. No charger is included. Use the charger that came with your JET 12–16 mm tool. If that charger is missing or faulty, it must be sourced separately.
- Contents: one 14.4 V, 3.0 Ah Li-ion battery.
- No charger, no strap, no seals, no carry case.
- Fits the JET 12–16 mm battery strapping tool only.
Confirm your tool model before placing an order. Other battery strapping tools use different batteries and connectors.
