Good quality and holds charge well

Great battery, great charger, does exactly as it should efficiently. Good value for money.

Got this for the Einhell brad nailer I got that came without a battery or charger. I was going to get a second battery but this lasts longer than I expected, in fact I haven't needed to recharge it yet.

I am really a Makita fan but Makita didn't make the tool I was looking for at a price I was prepared to pay. So I investigated the Einhell range and decided to commit to a second battery platform to run alongside my Makita LXT platform. I duspythis will prove a sensible move from what I have seen. The battery feels and appears well made but only time will tell.

I have quickly discovered that the expensive part of battery-powered tools is the battery. It's sometimes cheapest to get a starter set with a drill, charger and batteries, even if you already have a drill! That's the route I decided to take, but my drill only had the 2AH batteries, and I wanted a bigger one for the circular saw I just bought. I didn't actually NEED a bigger battery as it turned out - these batteries are all pretty powerful, and I was able to cut through solid oak kitchen counter tops with the smaller 2AH batteries. The size has nothing to do with the available power, the only difference is that the bigger ones last longer. Nevertheless, it's useful to have plenty of batteries available. For jobs like kitchen fitting I've found that three is a good number - one in the drill, one in the impact screwdriver and one in the circular saw. Ideally another one in the charger... It gets expensive, which is why I made sure I got this in the sale. £40 for the battery and charger is not bad at all. I now have two chargers, which is always useful because I can have one in the workshop and one wherever I am working. From the older reviews it seems some came with an EU plug, but that seems to have been resolved now. My charger came with a UK plug on, so I was able to use it immediately. The battery had about 75% charge, so it didn't take long to fully charge it up. The charger has the usual lights to tell you if it's discharged, charging or full. The battery also has lights to tell you the charge status, which is handy. You just press a button next to the release catch. The battery only fits Einhell tools, officially. However, Einhell also make some of the tools sold by Lidl and Aldi, so you might find the batteries are interchangeable. The battery does NOT fit Makita, Bosch or Stanley Fatmax tools (old or new). You can get adapters... This 4AH battery is quite a lot heavier than the 2AH, which is worth remembering if you have to hold the thing over your head for any length of time. I guess that's why they make different sizes - use the right one for the job.
