I’m using the standard charger on all my batteries 2.0-12.0. I can wait and they will last much longer
@RowanHay-q5l3 ай бұрын
Excellent and informative video. Like others who have commented, I quite like a more modest charge rate when time allows. So the standard charger gets the most use with the smaller capacity batteries I tend to use. I own standard and rapid chargers. Thanks again.

Always had the understanding that slower charging will prolong the life of the battery
@BatteryTestChannel2 жыл бұрын
True, to an extent. There is such a thing as too slow! You can’t go wrong with a 1C charge for the most part. What that means is - if you have a 3000mAh battery, charge it at 3000mA, or 3A at the correct voltage. For a Li Ion, that’s around 3.7V average, or 12W. This is why the 12W USB charger makes a lot of sense for phones.

@@BatteryTestChannel Honest question: What about phones that have batteries around 4,000-5,000mah and have 30w or even 45w fast charging. Like the new Galaxy s23 Ultra? Is that harmful to the battery at that point?
@BatteryTestChannel Жыл бұрын
@@DarkestofTimes I don’t think they’re harmful, but they very much act like the V3 supercharger that Tesla uses. They charge at 45W for a short amount of time, and simply dive down to 25W for the rest. They’re 45W in name only in my opinion, and many of the tests prove it. Now what really scares me is the Realme phones that charge at 200W+ How the heck they do that is beyond me.

It's better to slow charge your batteries, super chargering isn't good for the cells. If you want your costly battery to last longer, don't rush the charge only if you absolutely need the juice.
@BatteryTestChannel2 жыл бұрын
Agreed! However, defining a “slow charge” depends on the physical size of the battery. If the battery chemistry is the same, a larger battery will charge at the same rate, at a higher current. Many modern chargers put out a standard charge rate, so while a supercharger charges a 12.0Ah at a “standard charge” speed, it definitely fast-charges the smaller battery. I hope that helps. Thank you for watching.

I did monitor temps and did not find an appreciable difference. I even charged the batteries “naked” and did time lapse testing with IR cameras but it really wasn’t much to report on so I just skipped it. The smaller batteries do heat up a lot more and warrants a video… eventually!

The regular charger eik take 4 long hours!! 2 hours with rapid and 1 hour with super. You got those perfectly. It’s actually around 55 minutes with the supercharger. The max power is very telling. ~80W, ~150W, ~335W.

so is it better to use a faster charger for the higher output batteries? i have the rapid charger and the standard charger but my thinking was a faster charger wouldn't do the batteries very good? i just try to alternate between the 2 with all my batteries
@BatteryTestChannel2 жыл бұрын
I would not use the Supercharger with 1.5 and 2.0Ah batteries. Otherwise, you’re safe to mix and match. The larger the battery, the more impact you’ll see overall as you pointed out. So yes, use the Rapid charger for the bigger pack, since there is lower stress that way. Also, use the standard charger if you can spare the time on the small packs.
@ericklein5097 Жыл бұрын
Once you know the current output each charger will have for each battery then use this formula 0.5C=preferred slow charging for power cells 1C=standard charging for power cells 2C=absolute limit for charging power cells and not all support a full 2C Charger Output (Amps)/Battery Capacity (Amp Hours) 13.5A/12Ah= just over 1C 6A/2Ah=3C no no no no bad I know the rapid charger can detect battery size from a BMS signal to prevent the smaller batteries from getting 13.5A but 6A is still quite a bit for medium batteries and too much for the smallest guys

Voltage does NOT represent state of charge. Its honestly besides the point anyways. Apples to Apples for this test is will be very minuscule to the end result. They are both 18 volt batteries. So the apples to apples analogy doesn't even apply either. Comparing apples to oranges would be like comparing M12 and M18. But you have two M18 batteries... so two apples. I bought two M18 5.0 batteries brand new and they both came blinking red. Put both of them on a dual rapid charger. And they literally finished within 5 seconds of eachother. I did not test the voltages or anything like that. This just goes to show that blinking red IS blinking red. Yeah maybe one is measuring slightly less voltage than the other but so what. Its really not even a big enough variable to even be considered inaccurate to the test. A good multimeter (like the true RMS Fluke meter you have) is displaying an average on the screen. That voltage number is not the exact number either. Its compiling the averages.
@BatteryTestChannel2 жыл бұрын
At the very end, the voltage curve falls off a cliff and is therefore meaningless. Perhaps I shouldn’t have mentioned this blinking since - as you said - they will finish within seconds of each other. I was just curious about the blinking behavior. While I agree that you cannot glean SoC purely from voltage, there absolutely is a correlation. It’s just a poor predictor due to a flat discharge curve. So it’s possible to get a ballpark curve. I just can’t tell you if its 40% or 60% because the curve is not linear. A rise from 3.2V to 3.7V is much less significant than 3.8V to 3.9V for example.

But you do a test on the supercharger versus the dual rapid M18 charger?
@enriquecardenas1335 Жыл бұрын
You missed the current, the super charger only supercharges the HO 6.0, 8.0 and 12 at 12 Amps and the rapid charges all M18 at 6 amps that’s the difference, the down of the SC is that over time it will degrade your batteries faster than the rapid, but not that much really, at 200 cycles it is expected to hold 80% of its capacity so it depends on what’s you do or what you want
@BatteryTestChannel Жыл бұрын
Yes, you’re right that the extra power only helps the HO batteries, except it also seems to pass a ton of current to the 1.5Ah and 2.0Ah M18 batteries!

Hi Bob. I'm using generic power meter off Amazon. If you simply search for "US Power meter" on Amazon (or ebay) - they will come up. They're reasonably accurate, I tested them with a 10x clamp accessory and it was within a couple of watts. I'm not giving you a direct link because it changes by the day - as you can tell by the two meters I have looking similar, yet being different with no label.

I think the reason for the blinking and non blinking is due to the chip inside the battery. It knows how much power it needs to do the next job so bottom battery is saying "no I can't drill that next hole" and the top battery has been reset so it's ready to try something. EVEN though it won't go

@@nightmareinaction629 Good idea! I do have two M18 lights. I can measure current draw and confirm that they are equivalent and use them as a load. I’m also into RC, and do have a SkyRC B6 i could use. I’d need to wire up a balance charge connector to the battery, which will get a little dicey… It’d be a lot easier with an M12 battery, since it’s 3D instead of 5S.

Wrong, that is a feature unique to LiFePO4. NMC/NCA lithium ion can be reliably correlated to State of Charge with an Open Circuit Voltage after the cell has rested without a load for at least an hour.
