Im done with buying cheap Chinese rip offs from eBay or Allie. Latest item was a remote control for Amazon Firestick. Lasted all of 48 hours. Given the risk of lithium batteries, they are the last on the list of items Id buy from knock off vendors.

 Same here... I use Milwaukee and OEM battery are $150 and last about 2-3 years of daily use... The $65 knock off from ebay, the lasting charge is about 2/3 and the life of the battery is about 6-8 months... They always die without a warning...

So after all, if you do the maths, you pay nearly the same either way you go, but the knock off battery have definitely less power/charge available even if the box says otherwise... When they die I normally keep the shell just in case one of the good battery shell breaks apart... If you also own a soldering iron, you can replace just the guts of most power tools batteries with new Li-Ion 18650 (most common size). Plenty of youtube video to show you how..

I too have had an Ozito drill fail after a couple of months use, now use Bosch gear. If you are happy that's all that matters. It's your money Dicko.

 Yes, rightly so. Especially with a no quibble 5 year exchange warranty.

I must be the odd one out here. I heard that down the back.

I use Ryobi 18v one+ and have a selection of their range and very happy with them all. I have a 5ah and a 2ah battery and just work with those. I live in an aluminium tent so don't need other expensive ones.



Keep Safe on the roads and out there.

Ive been using Ozito Batteries for some years and never had one fail. I have even got some adapters so I can use them as spares for some of my other 18v tools, Good value for money in my opinion.

 Same.  For roughly $100 you can buy 2 x 4Ah Ozito battieries and a double charger.  Compares very favourably with Makita batteries!

My issue isnt with Ozito, its with knock off battery copies from china that carry a risk.

So far, no problems encountered with "knock off battery copies" (photos provided) for my Ozito tools.

Which is the reason I originally posted here for other Ozito users.

The "genuine" Ozito batteries are three times the cost.

Do the sums regarding the "risk".

I have mostly dewalt power tools and I bought one of the no-name lithium batteries from ebay last year. It was noticeably lighter than the genuine battery. It provided power for approx 20% of the time that the genuine battery did despite claiming to be the same 5AH. It also lost charge if sitting unused for a week or two. Adding to this was the fact that I wasn't game to trust it to charge unless I was in the room (who knows how safe theses cheapies are?) so I disposed of it at the appropriate battery recycling place.

I ended up buying another dewalt power tool which came with another battery and charger. Because it was on sale, it wasn't much more than the cost of buying a battery on it's own.

I found a Milwaukee 18v vacuum in the bin. It was stuffed full. But it seemed to work as there was a battery in it, but almost flat.

I only have Bosch so bridged the Milwaukee battery in parallel with a Bosch. Both at the same level of charge, fairly flat.

I kept a close eye on the charging, abate twice as long to charge.

Tested the vacuum & it seemed to be fine.

 

Anyway, I gave it to my neighbour who has a bit of Milwaukee stuff. I said I don't want to start up another system. He was very grateful, more so having a second battery.

A few weeks later he said the battery with the vacuum was an original. But he had a copy battery for his tools. He said the original battery performed much better than his copy battery.

Thanks, but I still couldn't be bothered. The only time I needed all my 18v batteries, 2 x 8AH & 4 x 5AH was cutting up a decent size tree with the Bosch chain saw. Might get a 12AH battery or two.

I think the comments are fair enough about certain cheap Chinese batteries.

As an alternative for the Ozito DIY'er you can get a case only for about $20 and 10 x Eve or Molicel 18650 3500mah batteries for about $65.

As I understand, these are regarded as quality batteries according to Internet opinions. This arrangement should result in true 6-7ah battery packs.

You would require a hand held spot welder and soldering iron. I have a spot welder that cost $70. I think everyone has a soldering iron.

So $140 for a genuine Ozito 6ah battery or knock one up yourself for $85 knowing the batteries are of good quality.

Also, a 3ah Ozito battery is $80. If the 6ah cheap knock off is equivalent to 3ah and costs $45 you are still ahead.

I will be testing a 6ah "cheapie" this week and will post results.

 

Not bad for $20.

I've tried cheapies and had poor results,   but I do remember being told a quote by a rep when I went into business. 

"Quality is remembered,  long after price is forgotten" 

It still holds true.

 

Thanks Dicko , A good review.

Tested neighbors 6ah "cheapie" battery for Ozito power exchange tools.

Firstly, although the sellers claim 6Ah capacity it appears that 6Wh (see battery pics) calculation has been used, which can be viewed as misinformation, as we would normally calculate electrical charge capacity in Amp Hours.

So, the sellers are actually claiming around twice the actual capacity.

The battery I tested had a bank of 10 x 1800Mah x 3.7V batteries providing 3.6Ah at 18V. The discharge test seemed to support this result. Fyi, the batteries are IMR chemistry.

I used an Ozito heat gun for the test, charging and discharging the battery 15 times. It was also a good test for the Ozito heat gun, which performed well.

The genuine Ozito (4Ah) battery took precisely 17 minutes to discharge from fully charged.

The "cheapie" (3.6Ah) battery took 15 minutes to discharge from fully charged and repeated the same result on 15 occasions.

The test results seem to show that the "cheapie" and genuine batteries have similar discharge rates.

The genuine Ozito battery (4Ah) costs $69 currently at Bunnings. The "cheapie" battery costs $44.50 including freight. A saving of $24.50.

The test shows that, in my opinion, the saving is justified. Make your own conclusions.

In addition, I have provided a tear-down of the "cheapie", and again in my opinion, the build appears of a high quality. How long the batteries last time will tell, however, 15 recharges and discharges did show the same results.

I am looking at other alternatives (more of a DIY nature) to save costs and will report on those soon.

 Perhaps I misunderstood your post, but I would say that you tested two batteries that are both "cheapie"... The main difference here is that, for one you also have paid for Bunnings commission (the extra $24.50)...

I think that a real test would include an expensive Brand battery (Bosch, DeWalt, Milwaukee, Makita, Festool, (you know... the brands used by workshops and tradies)), against the cheaper brands like Ozito, Ryobi, Rockwell, the new gen Black & Decker, the new Stanley, the old GMC...

It is then that I know you will see the difference, as we did in the workshop, where the expensive brand batteries just leave the cheap brand (same name but less than half the cost from Ebay, Aliexpress....), in the dust on both power, discharge time and tool performance...

Now, don't get me wrong here... I think it is good that we have a choice... If I used a drill only 50-100 times per year I wouldn't want to pay $600, but I would be more than happy to go with a Ryobi for $99 or an Ozito for $49...

But when your income depends on your tools working every day and perform the same every day, that's when you need a battery that does last... Batteries is a big business, and we need to compare apple for apple... There are so many variations of chemicals and electronic board components inside those little powerhouses, that just because two battery quotes the same Voltage/Ah, it still doesn't mean that they will perform the same...

In my personal experience (we are a workshop of 12 people) the cheap brand batteries and tools, simply don't last if used every day... However, they are a great option for the occasional user...

When in my first reply, I mentioned cheap batteries not holding up against the expensive one, this is what I meant... If you want to make a comparison try between a $160 battery and a $50 battery even if the same brand...

Thank you for the input.

My post refers to DIY users, like myself, who Ozito brand users would be.

If Ozito branded batteries are regarded as "cheapies" then all I can say is that my batteries have performed admirably well over the years and continue to do so.

I have an extensive range of cordless tools and decided from the beginning to go with a particular brand for the sake of common batteries.

The tools are used, as required, for the occasional purposes in garden and DIY projects. The quality of the product is not what I have focused upon here.

What I have been concerned about is the actual cost of original batteries compared to alternative available batteries.

What I have realised is one needs to be aware of misleading advertising, as I have already mentioned earlier. My tests revealed actual half capacity of what you get when not being able to view the internal batteries.

However, so far, the batteries themselves actually performed well at their proper rated capacities. It's the advertising that is misleading.

I have taken this to the next level, whereby, I will have a clearer view of what I am seeking with the associated cost savings. It will involve DIY on my part.

I will post my test results when completed.

 I was just going by your first post... You mentioned an Ozito 6Ah for $139.. My 6Ah Milwaukee sell for $259.. That's a big difference in price for the same Ah... The Ozito 8Ah sell for $179 Again we pay $389 for an 8Ah... I can buy online the 5Ah for around the $60... These are the cheapie battery I was referring too... The one from Ebay of the Milwaukee brand...

Another suggestion I got, would be to feel the weight of the battery.. Not always, but the brand batteries tend to be heavier than the cheapie on ebay... I still buy occasionally the cheap from Ebay to get the shell for my good ones that tend to crack very often due to operator abuse...

 

Edit:

I was just looking at Bunnings prices for Ozito batteries... I think the two 5.2Ah pack for $179 is even a better deal than the single 6/4Ah for $139.. That's an extra 4Ah for only $30...

On a different matter, they also sell a Ryobi angle grinder for less than $6
