Wolf Garten Power 60 plus 3.7V Hedge Shear Replacement Battery

My Wolf Garten hedge shear cuts fine for a few passes then the blades slow down and it feels like it's struggling — new battery fitted yesterday

This is voltage sag under load — common in single-cell 3.7V Li-ion packs when the cell hasn't been through a full conditioning cycle after replacement. The tool's motor draws a brief current spike each time the blades engage, and a new cell that's never been fully discharged and recharged will drop voltage faster than a settled one. Run the shear until it cuts out naturally, charge it fully, and repeat that cycle twice before judging performance. After two full cycles, check resting voltage with a multimeter — a healthy 3.7V cell should sit between 4.1V and 4.2V fully charged.

Replaced the battery in my Wolf Garten Power 60 plus and now the charger just blinks and won't go to solid green — never finishes charging

A blinking charge light that won't resolve usually means the charger is detecting a cell voltage below its recovery threshold — this happens when a new Li-ion cell has self-discharged during storage to the point the charger treats it as a fault rather than a depleted pack. Leave the battery connected for 20–30 minutes anyway — some chargers will attempt a trickle pre-charge to bring the cell up before switching to normal charge mode. If the light stays blinking past that point, check that the battery contacts are seated cleanly and free of debris, since a poor connection at the 66mm pack's terminal face mimics the same fault signal. If resting cell voltage reads below 2.5V on a multimeter, the cell has over-discharged and the charger won't recover it.

My hedge shear worked great last autumn, sat in the shed all winter with the battery in, now it won't turn on at all

Li-ion cells at 3.7V nominal self-discharge at roughly 2–3% per month, so after five or six months in an unheated shed the cell will have dropped below the protection circuit's cutoff — the pack's built-in BMS locks it out to prevent damage and the tool shows no signs of life. This is one of the most common issues with single-cell garden tools left stored with a partial charge. Put it on charge immediately and leave it for a full uninterrupted cycle — if the charger accepts it, the BMS may reset as voltage climbs back into range. If there's no charge indicator activity at all after 30 minutes, measure voltage at the battery terminals — anything below 2.5V means the cell is outside recoverable range and the pack needs replacing.
