My eight.4V 180mA (9 volt PP3 replacements) reach a final voltage of around 10 volts at a 0.1C (18mA) charge rate. A final voltage setting of 9V shall be too low for an 8.4V nominal NiMH to charge greater than about 20% most. Jim you don’t have a (nominal) 9V NiMH battery, because the nominal voltage will be a a number of of 1.2. So you've a NiMH in the kind issue of a 9V (PP3) battery, however the precise nominal voltage will most likely be both 7.2 volts or eight.four volts.

If your charger charges at a high charge fee, do a temperature verify. Lukewarm indicates that the batteries may be full. It is healthier to take away the batteries early and recharge earlier than each use than to leave them in the charger for eventual use.

In everything I’ve learn it seems that the worst enemy of Ni-MH is over-charging. My interest is in the long run well being of the cell. Would the cell undergo any negative side affects if it was repeatedly charged to solely 90% of charge each cycle, maybe by charging at .2C and terminating when deltaT simply starts to extend. Consumer chargers don't always terminate the charge accurately. Discontinue utilizing a charger that “cooks” batteries.

The Floureon 7.4V 5200mAh 2S Hard Case Lipo is a popular selection in the RC community. The battery will get combined reviews, though, depending on the fashions it’s used for.

I’ve bought several dozen from totally different closeout places hoping they’re okay. How many Ni/Cd cells (failure) can be changed per used battery? Is any specified limit for changing the cell per aircraft NiCd battery. I am unsure if the batteries are damaged or the charger don't cost the batteries since you damaged the safety?
