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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Definitely worth getting the bigger battery *by M***A on 21 November 2024* Much better battery as I don't have to charge up so often, the smaller one I was charging all the time I can use this one and don't worry about getting it stuck in field while sorting horses as battery lasts a good 30 mins more.... ### ⭐⭐⭐⭐⭐ Greenworks battery *by S***E on 26 September 2024* Excellent battery pack.
