Questions about this item

Does the 18 V lithium pack deliver the full 108.0 Wh rating in daily use?

The pack is rated at 18.0 V and 6000 mAh, giving a nominal 108.0 Wh; actual delivered energy depends on load, temperature and the tool’s cut-off voltage.

Will the 134.3 × 79.2 × 89.5 mm case fit my Fromm P328 strapping tool?

Yes, the battery is built to the original Fromm P328/P329/P327/P318/P326 dimensions, so it slides into the tool’s battery bay without modification.

How do I install the replacement pack, and what step do users often miss?

Slide the pack into the tool until the latch clicks, then run a full charge cycle before first use; skipping that initial charge is the most common mistake.
