About the  Black and Decker LSTE523 String Trimmer

With a LB2X3020 20V MAX Lithium Battery and charger the Black and Decker LSTE523 is a battery powered weed eater.

It uses their Power Drive Transmission system which increases the torque as you approach heavier areas of grass or weeds to give your more power to cut through them.

Taking a closer look:

It also has a two speed control which allows you to choose between 5500 and 7200 rpm. At 5500 rpm you get longer runtime and at 7200 rpm you get more power.

It converts from a trimmer to a wheeled edger by twisting the shaft and is part of the Black and Decker Power Command family of tools.

What does this mean for you?

It means you can swap the head that comes with it and replace it with the Power Command Hedge Trimmer and Power Command Sweeper accessories (that have to be bought separately).

It uses a single line manual feed system that advances your line with the push of a button. The line diameter is 0.065inches and the cutting diameter is 12 inches. It also has an adjustable shaft and handle.

What about the battery I hear you say?

Well the 1.5Ah battery takes around 3 hours and 45 minutes to fully charge, which means a 4Ah battery would take around ten hours to charge!

The length of use you get from the 1.5Ah battery depends upon the intensity you use it at, but it is around 20 to 40 minutes.

The Good

What sets the Black and Decker LSTE523 apart from many of its competitors is the push button string release function.

Does it work? You bet your bottom dollar it does!

It works perfectly and is head and shoulders above most of the auto feed systems other models use – which usually don’t work very well!

Simply push the button on the handle when the line is getting short and more string is let out, no tangling, no problems, just a great trimmer experience.

Good news:

It also uses the same spools (AF-100 pre-wound) that their other models that use 0.065inch line use.

For suburban moderate sized yards this generates easily enough power to handle thick weeds and tall overgrown grass – you won’t be disappointed.

Above: The Black and Decker LSTE523 has a great manual feed line.

Hands up:

I am a big fan of the dual speed option you get with the LSTE523. You can switch between the 5500 rpm mode and the 7200 rpm mode by flicking a button.

The 5500 rpm mode is okay for light grass and will give you a longer run time, however it struggles a bit on tougher weeds.

That is when you can switch to the 7200 rpm mode, which takes care of the tougher weeds but will run down the battery more quickly.

Taking it even further:

It is relatively lightweight and has one of the most comfortable handle grips I’ve used, with the soft material intelligently contoured to fit your hand, making it ultra comfortable to use.

There is also a safety catch on the handle that you need to hold down with your thumb before you can power it up. It is conveniently placed and makes the unit more secure.

This is neat:

It has a flip-to-edge collar, that means you can switch between trimming and edging without worrying about adjusting the shaft length as you might usually have to do.

This makes flipping between the two modes really simple – so less time mucking about doing that, meaning you will get your lawn looking shipshape more quickly.

The construction is solid – that isn’t to say there aren’t plastic pieces – there are quite a few, but the plastic parts do not feel flimsy or easily breakable.

To top it all off:

As mentioned before it is part of the Power Command line of tools, so you can buy a hedge trimmer and sweeper/leaf blower accessory to use with it (simply remove the trimmer head). This offers a good value for money option.

The Not So Good

The big problem with this string trimmer is the battery and the charger.

To be frank:

The 1.5Ah battery runs out pretty quickly, even on smaller yards. It lasts around 20 minutes on the high setting and about 40 minutes on the lower setting. If you order it with the 1.5Ah battery, you actually get two batteries, which does help a bit. Or you can order a higher capacity battery which would be more expensive but last longer.

The batteries also don’t have a gauge or an indicator of how much battery life is left, which is also an annoyance.

And this compounds the problem:

The charger you get with this is pretty poor. It takes around 3 hours and 45 minutes to fully charge a 1.5Ah battery. Compared to the EGO Power String Trimmer, which takes 40 minutes to fully charge a 2.0Ah battery you can see the problem!

I am not sure why Black and Decker don’t utilise the normal lithium ion techniques used by the likes of EGO Power and Makita, etc. It means you really have to plan your weed whacking sessions!

That would make much more sense!

You can set the handle to one of three lock points but they do sometimes come loose. It just vibrates out of the lock and drops to the next one. Not a game changer, just annoying.

Even though the shaft is adjustable, it is a touch short even at the longest setting, which might give you a big of a backache when you are trimming.

Finally:

The ergonomics of the edger mean it is more uncomfortable to use than the trimmer. You will probably need to break occasionally to save fatigue on the back and arms.

There is also no metal edge guide which makes it more difficult to stay on track, and it inevitably takes longer as you have to go slower.

FAQs

What is the advantage of having two 1.5Ah batteries rather than one 3.0Ah battery?
The main thing is the 3.0Ah battery weighs about twice that of 1.5Ah battery so it would be top heavy.
Can you load your own line or should you use the preloaded spools?
There are instructions in the manual that show you how to reload the spool, but I think the preloaded spools are much better.
Can a thicker line be used?
No it only takes the specified line.

There are some fantastic weed eaters on the market right now and for what it is worth this is one of them!

My favourite is the Ego Power String Trimmer – it is battery powered and it is great! Another good option is the WORX WG154. To the right are a list of general resources that maybe be of use.

Conclusion

My Verdict

91%

Summary All in all this is an excellent purchase and one of the few weed eaters that can offer a virtually flaw free line feed system, which is almost worth the money alone!

Aside from that it is plenty good enough if you have a standard suburban yard and don’t want the hassle or restrictions of gas or a cord. As long as you aren’t tackling anything out of the ordinary it will certainly will have enough power for you and the dual power system is good for taking care if you are trimming around a more delicate area of your lawn.

You need to weigh up the cons of the battery and charger before you decide whether to get this, but if your yard isn’t too big it will be absolutely fine - in fact it will be better than that it will be great!

    I’ve had several Black and Decker power tools. They have been good, but not great tools. Of course the great tools cost quite a bit more. My current trimmer requires an extension cord, which a bigger pain than a short life battery. Next time I’m going to get a battery powered trimmer. Maybe a Black and Decker, it will depend on price and my budget. Thanks for your post.

      I think you are right Grant. They are good, some bordering on great, and reliable, but there are better brands on the market. If you want a good battery power string trimmer go for the EGO Power+ ST1500 it is great!

    We have a collection of trimmers at our house. Some are corded and are no longer used. We have a Gas trimmer that my husband uses from time to time but it’s a pain to mix the fuel for it and then never mind handle it. I would love a battery powered one like this one, but would definitely want two batteries. I doubt we could get our trimming jobs done in 20 minutes, not with 4 acres. I like the features of this one and it looks easy to handle as well.

      I understand what you mean re the Gas trimmer – it can be a pain mixing fuel. Depending on your budget my favourite weed eater is the EGO Power+ ST1500, but the WORX WG154 is also a good option and a bit cheaper.
