UltraSmartCharger Forum

More info on burping - seems it has a history going back to the late 1960 s - and a bit of a sordid history it is. I might just be posting a link to fake news but here is the link - Burp Charging History After the patent was awarded he took it to General Electric, then the leading Ni-Cd manufacturer...

http://www.mpoweruk.com/chargers.htm Burp charging Also called Reflex or Negative Pulse Charging Used in conjunction with pulse charging, it applies a very short discharge pulse, typically 2 to 3 times the charging current for 5 milliseconds, during the charging rest period to depolarise the cell. T...

Reading around on CPF, I found one of Paul's early threads on the USC (ultra smart...). The voltage is measured both during charging and like yours, during a "brief off-charge", or in my case a 1.5 seconds discharge So it does use discharge during charge. I don't recall reading that in the...

The UltraSmartCharger already does a lot of those things. I realize :D - just trying to be feature complete. To be honest with you, I'm dubious about a lot of the things that you're suggesting that the charger doesn't already do. Do you have anything that you can point me to that indicates a benefi...

Discharging a regular Nicad battery below 0.9 at a very low discharge rate was determined to "renew" the cell capacity. Something on the order of C/40 or C/50. This is the article on BatteryUniversity . So...that goes for NiCad. But the article's title is "How to Restore Nickel-based ...

As I see it the charger should try to keep the battery as healthy as possible, to allow for the maximum number of cycles. The end user charger has no control of how a battery is drained, or how long it is left drained - so that is beyond its scope. Charging then, breaks down into five phases. ⋅...

Any progress? Also, it might be interesting to find the testing criteria established by International Electrotechnical Commission for battery testing. *charge capacity and mAh estimates based on Panasonic internal IEC 61951-2(7.3.2) testing. **Recharge cycles based on testing method established by ...

So, I'm not on the kickstarter list...are the units shipping to regular purchasers yet?
If so, what is the backlog time please?

Found someone who had performed some testing on the new LADDA batteries. Only test for discharge graph (single) and capacity just out of wrapper and after a few cycles. It is a google translate from Russian..so the language is 'non optimal' :roll: Russian "Se7en solution" LADDA 2450 & ...

Got a PDF from a trade show. Blah-blah blah Panasonic, Eneloop etc. However their new "smart" charger the BQ-CC55 claims it does NOT used Delta V but instead a "Peak Sensing Technology". They have a graphic of the charge cycle along with a blow-up of one part of the cycle. Check ...
