As a budget DIYer and gardner, I've just started adding a few Parkside tools to my Einhell collection. I think both ranges are great value for money. I had heard that not only do 4Ah batteries last longer but also deliver a bit more power. Until this video however I didn't realise how big a difference. Will definately buy this saw without the 2Ah batteries and use my own 4Ah. Dzięki bardzo.

Interesting test. I remember the last test you did with the Parkside saw. On that test, you concluded that the saw was underpowered for the tasks you set it. Most of us would be using that small cordless saw to rip sheet material up to 19mm, rather than a stack of 6x2s or fence posts. However, you are quite correct: using the 4ah battery does give longer run time and more power. I've heard people complain about the 1.5 and 2.0ah batteries before, but if you are using a cordless drill or impact driver, the lower powered - and lighter - batteries are more than adequate for the task, not to mention more comfortable to work with.

You cannot beat real world proof before your eyes.Great video.👌👍

My parkside circular saw died the other day after 3 years of DIY use but only after a hit a deck screw. Only got one 4amp battery that mainly gets used in the saw but occasionally if only cutting 11mm OSB for short lengths the 2amp battery will manage whilst other is charging. I enjoyed your video Tomas . Thanks for sharing

I found this with the 20v angle grinder I have from Parkside. The 2ah batteries would just stop very quickly. I've started buying the 4ah batteries to improve performance and power delivery. I'm going to be buying the circular saw next and that will be on the 4ah batteries permanently.

Fantastic testing, Tomasz! Thanks! 😃 The 4AH battery should also have a more powerful BMS, otherwise it would work exactly the same. It definitely needs to give more current! Anyway, stay safe there with your family! 🖖😊

I have two of the 8ah batteries and for the most demanding machines (leaf blower, angle grinder) you can see a significant jump in performance compared to the 4ah. On the parkside performance angle grinder specifically, 2ah are basically unusable. If using a flap grinding disc you press even a bit the machine slows down and stops. The 4ah is adequate, but you can't press firmly. With the 8ah doesn't care, you have to actively try to stall the disk pressing strongly to get it to stop.

Congratulations on what you do !!!

Interesting test 👍 You failed to mention if both of the batteries the were the same age with the same usage, or if one was older/used more! In both cases, when cutting the fence post the result was absolutely pathetic ... even at full depth cut (it's a small blade) I'd have expected it to cut the length of the post without issue ... you've convinced me never to buy one of these saws 😀

When I bought mine people were really slating it as being poor. Granted I probably wouldn't use it to cut fence posts but for sheet materials its really great. Last weekend I was using it on 18mm chipboard and it was like a hot knife though butter (4Ah battery used). My only issue I've experienced is the initial movement of the guard when it hits the material is awkward, feels like it sticks and can put your cut off. Keep meaning to have a look at that.

Keep the channel going, you are a sweet guy :) Try the new smart batteries PARKSIDE PERFORMANCE Smart accu 20 V, 8 Ah »PAPS 208 A1« these are powerful batteries

Interesting as usual Tomasz but I'm not sure if I'm convinced by your verdict. Obviously, the 4AH will last longer than the 2AH battery but what makes you also believe that it delivers more power,? To me, it delivers the same power to the saw but for a longer period. My main takeaway is to never consider buying a 2AH battery for a power tool.

Corded is probably better then, or the 40v version.

Hi, I bought a parkside cordless hand held circular saw and made about 5-6 cuts and then it stopped working but the laser works and the battery is fine. Please don't know what to do with it?

Try 8Ah with Bluetooth 😉
