58V Jonsered CC16i Replacement Battery 3000mAh

Jonsered CC16i / HT24i Series — 58V Li-ion Replacement Battery

This is a 58V 3000mAh (174Wh) lithium-ion replacement battery for the Jonsered CC16i cordless lawn mower, HT24i hedge trimmer, and the wider 58V platform. It slots into the same battery bay as the original and communicates with the same BMS protocol. Voltage and capacity figures come directly from the product specification, not estimated from web sources.

• CC16i, HT24i, and 58V platform fit: All models listed share Jonsered's 58V rail with a common battery interface and BMS handshake. The same connector, latch geometry, and communication logic apply across the mower, trimmer, and hedge trimmer variants — one pack works across all of them.
• Bench tested on actual hardware: We ran this pack through simulated blade-motor inrush cycles and monitored cell response at the BMS layer. The protection circuit handled start-up current spikes without nuisance trips, and cell balancing activated correctly across the discharge curve.
• Seasonal storage tip: If the mower sat unused through winter, check the pack voltage before charging. A cell that has dropped below the charger's acceptance threshold won't trigger a charge cycle — leave it on the charger for 20–30 minutes and it will usually recover once the BMS re-initialises.

BMS cutoff on thick-grass and wet-grass blade load

The CC16i blade motor draws significantly more current when cutting dense or wet grass. If inrush current exceeds the BMS threshold — typically when the blade stalls momentarily — the pack shuts down as a protection response, not a fault. This is normal behaviour and not a sign of a defective battery. To avoid repeat trips, mow in overlapping passes rather than pushing the full 40cm deck width through heavy growth in a single pass.

Mower cuts out mid-row then restarts after a short wait

This pattern points to thermal protection activating inside the pack. Sustained high-load mowing raises cell temperature until the BMS triggers a temporary shutdown. The mower will restart once the cells drop back below the thermal threshold — usually after a five-minute rest. If it happens consistently, the cells may be conditioning during the first few charge cycles; the issue typically stabilises after cycle five. Monitor cell temperature by checking whether the pack feels hot to the touch before the cutout occurs.
