Hi I've been doing some testing with the battery triple a sleeve and if you've been following me on the EEV blog forum thread or on Twitter or or on my second channel, you would have seen us and testing of this as you recently did some live stuff. but a lot of people I think would be interested in seeing this. hence I'm putting on my main channels just an unnumbered video. I'll be doing more detailed videos in the future, but I Just thought this is important enough now.

Battery have separated their claims now into the difference between active loads and passive loads and okay, fair enough. So I thought we died. This video is to do with testing the passive loads. Now they claim that you can get increased performance on passive loads and you'll see that's kind of true here in the results that we're going to get.

So I'm going to use this. Imaginarium Triple A Powered Train engine which I got from the local Were Toys R Us store is very representative of a passive load. Here's a look inside. it's just a basic DC motor with a reversing switch on I can go forward and reverse and a light bulb on the front.

so just purely passive load motor and a light bulb. that's basically it. So a classic example of a toy that people would use this batteries ER in. So let's have a look to see if we actually get increase performance out of this thing now.

I'll do the full testing video at the end so that you can watch it, but let's just discuss the results up front. now. they were about about two and a half thousand people who actually watch me do this live test on the Eevblog main channel. So I'll link that in down below if you want to watch it.

but let's have a look here. I've actually glued the track down to the base here so that it doesn't move and I've set up my event counter I did a previous video on that or a lap counter here so I'll count some number of laps and I've got a basic timer there. so I shot these two are separately in a single take as you saw as you'll see in the full video which is over on my second channel. I've gotten the full, uninterrupted unedited thing We're using two Duracell Copper Top Standard Duracell Copper top triple-a batteries and I ran one test without the batteries and one test with the batteries ER and now I've edited those clips, sync them up, put them side-by-side and we can see the result, and we're off and running on the left hand side, we've got the train without the batteries.

On the right hand side, we've got the trained with the batteries ER and Spoiler alert the one without the battery. so it runs for a greater amount of time and a greater number of laps. But hey, battery claim that it's all about the performance, right? So that in the case of a train, performance would be that train runs faster. Well, okay, we can get some quantitative data on that.

What I've done has gone through the time line in the video at regular time intervals. this is sped up ten times by the way, and I got the number of laps counted the number of laps at each point linear point during that period and we can graph the result and it's very interesting. What we've got here is the number of laps on our Y-axis versus the minutes in run time on our X-axis and the orange curve there is with the batter Iser and the blue one is without the batter Iser and you can see that both of them are fairly linear sort of. You know there's not much in it at all.

which means that they're basically both got a constant velocity. But yes, you'll note that the train with the batter Iser has a faster, constant velocity. And of course, you'd expect this because it's putting out a fixed 1.5 volts for the entire virtually the entire run time. That's its job.

it's a boost converter, so hence it does actually maximize their the performance of this train here right up until the point where it dies at a 94 minute mark. And of course, the other one without the batter Iser just keeps on going. It actually goes for 169 minutes before it dies. Now the interesting thing about this is okay.

it might have increased performance, but how much? Well, we can get some quantitative data on that. If you actually plot the difference between the two which is the relative velocity, you'll see that you know there's only like a 10 odd percent faster velocity for the train with the batter, and it's that's mostly the same over the performance. You know it goes up a bit, but it's sort of, you know Peaks around that value. So it's not like it's drastically faster.

So imagine you're a you know, five-year-old kid and you've got this toy chain for Christmas What would you rather have a toy train that's basically in perceivably faster five to ten percent? Or would you rather have one that does runs for an extra 75 minutes and 157 laps or 80 percent more run time and 44 percent more laps? I Think the answers obvious and if you think this is just an anomaly with the particular train I'm using, well. Frank Bus from the EEV blog forum. He also has a triple A battery so from exactly the same source as I got mine from and he ran it on a Brio brand battery-powered engine, it is a different one Once again, single triple-a and he only got 59 minutes run time with the battery. so compared to a hundred and twenty seven minutes without the battery, So so that's actually worse than my one.

And just in case you're about to say Dave you're not supposed to put the batteries er on The a brand new battery in a product. Well, let's go to the website and have a look. Does the battery need to be dead before I can start to use on the battery boost? No, you can start using battery boost at any time, even a brand new battery and you'll get the benefits of extended battery life. So that's what we just tested.

and they've been saying this from day one as well. Nothing different, but hey, it's a reasonable question. How much extra battery life do we get on a passive product like this? from that battery that we just did with the train without the batterer Iser it drained down. it was dead.

How much will extra life? How many extra laps will we get out of it if we whack the batter eyes are on. Let's find out it has stopped at one hour and 35 minutes. so that was with the batteries at 350 one laps so it failed on two different metrics. One was a the time, it was nowhere near the other one and nowhere near the number of laps.

Got over 500 laps. This was only three hundred and fifty-one laps. So that is a complete and utter fail of the better. Iser So there you go.

Um, let's actually measure that. Let me get my multimeter measure that it just came out fresh. Sammis Quiz? Oh sorry. Um yeah No.

I Still got the batteries a sleeve on right? It's Still giving out 1.5 The battery is still working, but um, course the battery. So let's take the better as a sleeve off one point one eight volts. What we'll do now is we will take the number one battery that we got before. Okay, so this is the dead battery that we were that we had in the train before and we'll put it back in and we'll see how many extra laps it will get on that.

Okay, so battery number one in the battery's a sleeve into the Train Yes. Okay, so we'll reset our count. so we got 350 one there and we'll go one plus plus and we'll restart that. So an hour and 36 minutes it went for with the battery.

So that was a complete and utter fail. So we'll whack it on and oh no way we go. Start. Alright, we are back up and running.

So this is the better riser on the already discharged battery in the train so we'll see how much extra time it gives us. but hey, it's already a fail. The batteries err in a passive train toy like this. Just a passive motor, nothing else.

There's no active circuitry inside this thing. It is driving a LED as well. There's a little LED light on the the thing and we'll see how many laps and how much extra time it gives us on this, but it's already failed. You work it on a new battery and it is.

thumbs down. You who picked it, who won the pool? Will it make it to the center? Will it make it to the sensor? It made 10 laps. It made double digits. but that is it.

It's still going. It might. we might get an extra lap out of it. But babe.

Basically that's dead. No kids gonna be happy. Had no kids gonna be happy with that. Not a chance they're gonna toss that better.

Iser Right outs. Lasted jaunt in like three and a half minutes or something. You saw it slow down there and it only got an extra ten laps out of that dead battery. So so much for that.

That is another aspect of the better Iser that has failed on this passive toy. So that actually fails on three different metrics on the new battery, both the number of laps and the minutes. It completely fails on that compared to a regular battery. And also it only gives you an extra or might just under two percent extra laps on a dead battery and 1.8 percent extra time.

That's a triple failure. Hey, that's a triple. Lindy Lindy That's impossible. So that's not eight times longer.

It's not eight hundred percent longer. It's not tapping into that eighty percent unused energy. What is it? What do we get here? Ah, 0.02 times longer? That's not point. O Two don't But hang on.

Surely the batteries err squeezes every last drop of energy out of that battery. right? right? Hmm, Now what I'm going to do as a bonus: I'm going to take the discharged battery that we number two that we discharged in the Bad: Arizer I'm going to so it should because the better Iser is got special whoo-whoo in it that uses all of the capacity in a battery, right? So we're going to put that back in the batteries a sleeve. So we've left it out for like ten minutes and we'll see if it gets any extra time on. the already better eyes are discharged Here we go.

So let's see how many extra laps our gets on the already discharged battery from the batteries up. The better Eyes are supposed to use all the energy from a battery. Apparently it doesn't. Who would have thought electrochemistry beats marketing Every day of the week, You and there you have it.

it is eking to a stop after almost one and a half minutes. we got an extra five laps with the battery that we had already discharged with the better. Iser We got half as many laps again as we did for the UM battery that was discharged battery without the battery. So this is laughable.

This is absolutely laughable. That arises, claims are like busted. Absolutely busted. That's number two battery.

Both of them are discharged and by the way, this one has been discharged twice with a better. Iser What I've got here is my lumen top tool triple-a That's the model the tool. So I'm going to take the battery which has been discharged twice in the batter Iser Now in the product in the product with the batter Iser and then again with the batter Iser I'm going to whack it in here without the batter Iser And it's look at that that's low eight, full brightness. Fulbright Nee can go into full brightness mode which is 110 lumens or something like that and that will run up if I put that on like medium or low mode low mode.

It'll last for hours and hours and hours still giving out usable light. So the batter: Iser It's busted. It is useless in a kid's toy training. I Did not select this toy train.

Similar results to what Frank Bus got on his toy train. It doesn't work with the mp3 player, it's it's hopeless act. Even passive devices both busted. Thumbs down.

It's going to be two thumbs down, surely. So there you go I Hope you enjoy to look at that data there and there is not any real benefit to be had on these particular are to toy trains that we've used here. In fact, the batteries er is to its detriment and that's really to be expected I Wouldn't expect it a massive velocity increase, that's you know that odd ten odd percent is kind of what I would expect although expected the one without the batter Iser to slow down a bit more, but it didn't so that was a rather interesting result which makes it even worse for the batter Iser But that is too passive toys and nope, it's not stacking up anywhere close to being worthwhile to use on these toy trains in it is kind of to be expected because of the power it's outputting a fixed 1.5 volts because it's a boost converter that's going to run the motor at that constant current as the battery voltage drops is going to draw more and more current from the battery and we need to go into the technical details in future videos and I certainly will. but of course it's going to increase more and more power from the battery and to basically not give you much increased velocity performance as batteries are out, calls it battery call it at all.

So really, it's yeah, it's a bit of a loser in these are passive devices. More testing to come but it ain't looking pretty and spoiler alert I Have done testing on an active load device in Mp3 player as has Frank bus once again two different ones and note the performance on an active device like a little portable single triple-a Mp3 player is no better so it ain't looking pretty. But anyway, look forward to future videos on this as I get more time because it takes a lot of time to do this sort of extensive testing and data gathering and editing and stuff like that anyway I will now leave you with like 10-15 minutes of the full train footage. Enjoy! Catch you next time you you the you.
