## Questions & Answers

**Q: This battery looks identical to my Swift 40v battery. Do you know if they are compatible?**
A: I'm afraid it is NOT compatible. Each OEM tends to make a form-factor unique to it's range of tools (no surprise there!!)

**Q: Does this fit the Qualcast lawnmower?**
A: Only green. Works appliances of the same voltage and ah

**Q: How long to charge at first?**
A: Hi Gary, not too long. About 1 - 2 hours. When you're mowing/strimming etc., and you exhaust the battery, it will be quite warm and won't charge until it has cooled down (generally after about 30 mins). Hope this helps

**Q: When battery is fitted to charger both lights immediately go out, with no battery in place charger power light stays on what needs replacing ?**
A: Under normal conditions, a flashing LED indicates that the battery is faulty - remove for 1 minute, unplug the charger and retry. If LED still flashes, replace the battery. If both lights go out, the battery is less than 10% charged - leave it in the charger and check the progress by pressing the BCI button. If the BCI remains unlit, then replace the battery.
