After market AEG OEM battery. Does not seem as robust as those that came with the original tools. No rubber impact corners and feels lighter in construction. Does the job so will see how things go.

Bought as my current batteries were not holding their charge. Impressed. What used to take me three batteries to do my pruning, whipper snipping and leave blowing I did with one 4ah and still had plenty of juice in reserve.

Good battery. Lighter battery. Smaller battery. Excellent performance. Better than the original AEG ones and smaller and lighter than the original Force battery.Yay I’m up to the minimum amount of words now.

I have invested heavily in AEG cordless products because of the improved quality of batteries and great reliability. A few points bother me. Sometimes the battery fit is too tight to easily remove it from the tool. Also AEG should make available a service to take back and recycle dead batteries and tools. But great warranty and range of tools.
I recently recieved the 4Ah battery pack for my power tools and I am extremely impressed with its performance. The battery provides a long runtime, allowing me to complete multiple projects without having to recharge. The battery is also lightweight and compact, making it easy to carry and store.One of the standout features of this battery pack is its quick charging time. I can fully charge the battery in around an hours, which is a great convenience. I also appreciate that the battery pack has a built-in fuel gauge with 4 indecators (25% each), so I always know how much power is left.Overall, I highly recommend the 4Ah battery pack for anyone in need of a reliable and high-performance power tool battery. The battery provides long runtime, quick charging, and ... MoreI recently recieved the 4Ah battery pack for my power tools and I am extremely impressed with its performance.

They are good overall, I would love more grip on the bottom and more over all stability for the tool like their predecessors. Once had a battery that was displaying 4 bars go down to 1 bar and flashing in less then 2 mins not even being used that full 2 mins just went down for some reason and stopped working till being recharged
I have both 6.0ah and 4.0ah batteries, and I use 4.0ah more often than the other. The major point is that 4.0ah is lighter especially when I use drills or impact driver. These type of tools don't need high capacity of battery. A 4.0ah would probably last for a day.
I was a bit concerned at first that the battery gauge wasn’t working. I had done a lot of work with it and it had only lost one bar! You certainly get the full 4 amps out the battery. I find it easier to put in and pull out using the two tabs.
Purchased the line trimmer as we have a very large verge outside a large fence so cord was not an option. Going from a standard black and decker weed eater as a comparison and moved to an AEG to match my hand tools and share the batteries. Line trimmer it self does what it says on the tin well, good construction, nice long neck meaning you dont have to lean over, not too heavy even with the battery on and easy to spool out more cord when needed. To have a well rounded feedback there must be some draw backs... Having such a large area to cover the unit came with 4ah batteries which it sucks through very quickly. I have 6ah batteries in my set that were far more suited to the job and lasted more than what is required to do the area.As a second reason this product ... MorePurchased the line trimmer as we have a very large verge outside a large fence so cord was not an option.

I have 6ah batteries in my set that were far more suited to the job and lasted more than what is required to do the area.As a second reason this product works well (and why I purchased) was the adjustable hedge trimmer extension that was available on a deal by redemption. This arrived quickly and when connected to the motor half of the line trimmer gives a really long reach to trim the top of those pesky hedges. Having a tool that have multiple attachment really spreads the "cost per use" across a few function and makes the original outlay seem like much more like a bit of steal.All in all, I would say another good quality, strong offering from AEG. So far having bought a number of their products I would say this is well in line with them and will continue to purchase further items.
Love the extra power with the 6ah battery. Definitely last a lot longer. All my batteries have been 2ah & 4ah until now. So glad I went that bit higher with the 6ah... Mostly use it with the 18v Fusion Jet Blower & 18v Line Trimmer with Edger Attachment...
