About this replacement
Pellenc Vine Tying Machine — 7.2V Ni-MH Replacement Battery
This is a 7.2V 3000mAh Ni-MH replacement battery pack for the Pellenc AP25, P80, PE80, and Fixion AP25 battery-powered vine tying machines. These tools are used in vineyard operations to rapidly anchor grapevines to stakes and wires during training and pruning seasons. Voltage and capacity match the original spec: 7.2V, 3000mAh, 21.6Wh.
- AP25, P80, PE80, Fixion AP25 compatibility: These models share the same 7.2V power rail, battery bay dimensions, and connector interface, which is why one pack covers all four.
- Bench tested on actual hardware: We ran full charge/discharge cycles — the BMS held voltage stable under repetitive load and cut off cleanly at the low-voltage threshold without dropping into an unrecoverable state.
- First charge before field use: Ni-MH cells benefit from a full charge before first use — this conditions the cells and helps establish consistent capacity from the start.
Why Ni-MH chemistry suits vineyard tying tools
Ni-MH cells handle repetitive short-burst loads well — exactly what a tying machine produces with each tie cycle. They also tolerate temperature variation better than some lithium chemistries, which matters in early-morning vineyard conditions. At 3000mAh, this pack matches Pellenc's original capacity spec for the AP25 platform.
Pack not charging or cutting out mid-row — here's what's happening
Ni-MH packs left in a partially discharged state for extended periods can develop voltage depression, where individual cells fall out of balance and the charger fails to recognise a full pack. The fix is to run the pack down fully before the next charge cycle — most Pellenc chargers will then reset and charge the cells back to balanced capacity. If the issue persists across multiple cycles, the cells have likely degraded past recovery and the pack needs replacement.
