Battery with satisfactory duration compared to the slightly smaller 4 Ah ones. If you can find them on discount, they are much more worth it.

Good and with long battery life but quite heavy for prolonged use, especially if used in pairs. Recommended only for professionals...

I bought it for longer duration on an Ingo 1200 grinder that I have and it really makes a big difference compared to the 4Ah. So far, very good

Very good. It lasts for quite a long time in most of the tools I have, without having to stop to recharge.

I bought it together with the handheld vacuum from the same company... It may lack finesse and design... I charge it once a month with daily use... and the vacuum cleaner works like crazy...

The battery in the pruning chainsaw for pruning olive trees with a diameter of less than 10 centimeters lasts about two hours. I consider it a very good purchase.

Very good battery, a bit heavy, but I use it in a modeling wheel and it lasts 3 days on a single charge

Good battery with quite a long duration in Total's electric vacuum cleaner and in other tools (blower, chainsaw). I have charged it about 10 times so far and its performance has not dropped. No complaints so far

I am satisfied. The battery lasts a long time and has met my needs for small tasks around the house.

In terms of money quality, the battery is quite good; it has worked with the vacuum cleaner, the wheel, and the drill. It lasts for many hours.

Very good performance. For a screwdriver, I forget to charge it. On a wheel, it holds about 20 minutes of continuous use

I bought two 1.5 A batteries a year ago instead of one with a larger capacity for less weight. I am satisfied so far with their performance and considering their price, I think it is a very good purchase. I have bought a drill and an eccentric sander. For amateur use, they are excellent and again I mention the very good price compared to the corresponding branded ones. Although it is a relatively new company in Greece, I highly recommend Total tools.

It lasts a long time (4Ah, 5Ah), especially if you consider its cost, it is comparable to the most famous brands (Bosch, Makita, Dewalt). Total is value for money in everything it offers.

Awesome battery. long duration of use. I use it on a polisher and I believe it easily shines 2 large cars before needing a refill

With this battery, the chainsaw worked continuously for 1.5 hours, cutting branches and trunks ranging from 3 to 17 cm in diameter, while there was no indication that the battery was even close to running out... I stopped because I finished the job...

It is okay despite the weight in hand tools that we need more usage time (for the saw and the pruning tool of the 20V series)

Very good quality and durability...
Having similar ones from Bosch and Stanley, I can say that it is just one click lower in all aspects...
Having the 5ah and testing it on a Total Brushless garden blower on the large ladder, it lasts about 20-22 minutes...
Also, it has a very good lock on the 20+ tools and the risk of it falling or any other kind of carelessness is very small...
I give it 4 stars because I don't know how it will perform for professional use (multiple charges)...
I recommend it anyway...

Edit:
I also bought the 7.5ah... despite its weight (850g), it has a very long duration...
On a large garden blower, it lasts 30-35 minutes on a large ladder...
On a small blower, it lasts about 45 minutes on the large one...

When using the paint gun, it doesn't hold up to paint more than 15 boards of 4 meters. The painting was done in 1 hour with breaks.

It lasts at least 1 hour in use for the angle grinder that I bought. Continuous use. It would be good to have the large charger instead of the small one because if it is for professional use, it takes a long time for the battery to charge due to its size. If you don't care about charging time, then the small one does the job just fine.

For use in a drill driver, it easily handles mounting a large wardrobe and bedroom with one charge (tested). Anyway, I had a second one just in case, but it wasn't needed.
