I have a 12v 25 Ah lead acid battery used in a ups. The ups has 14v between the pos. And neg. Terminals. Would 10 nicad battery in series be a good substitute for the lead acid battery using the built in charger in the ups?

A good quality NiCd can last over 20 years. I know because I have some from the mid 90s that still work. Most good quality NiCd are ruined from over charging with too much charge current, which can rupture the vent and cause the cell to dry out, or from over discharge in packs, which causes cells to develop high a high self discharge rate and lose capacity from reverse charging. NiMH deteriorate with time, and they deteriorate faster when discharged, so they should be charged before storage. Lithium ion are good but like NiMH, they deteriorate with time and also especially with high temperature. Most lithium are also permanently damaged when fast charged in freezing temperatures.

I am going to buy a cordless impact wrench for wheel nuts etc for personal use ie it will only be used occasionally. It will be supplied with two new uncharged NiCd 24V 1.7 amp battery packs and I only intend using one of them. Long term storage of the other – would it be better to keep it in a fridge or a freezer?

thanks

to determine the minimum charging current of rated Ah

HEEEEEEEEEEELLLLLLLLPPPPP

I have a wheelchair battery pack with 168 sub-c ni-cads. 76 volts 7.5 amp hours What should each sub-c’s specs be if I make a new one? voltage of each cell? mah of each cell?

How long will a fully charged Ni-Cad battery maintain its charge when not in use, i.e. will the battery drain on its own?

One thing that bugs me is, IF its not going to be used for some time, and you want to use it now, like an Impact wrench, how often do you use these? one must charge it before using it. Now there is a wait time that must be encountered of 4-5 hrs. Inconvenient…..So do you keep it charged or not?

One thing that should never be done is to try running to completely dead in a multicell application, especially in a power tool, as cell reversal can happen. It is best to charge when the power tool suddenly loses some, but not all of its power. Trying to use it further is likely to cause the dendrites via metallic conductive hairs forming in the cells that went empty 1st, by the ones still having charge left in them.
