Technician a says that maintenance-free batteries use a large amount of water. technician b says that maintenance-free batteries use materials that reduce the amount of water used by the battery. which technician is correct
a. technician a
b. technician b
c. both a and b
d. neither a nor b

Option B

Explanation:

Maintenance-free battery uses Recom­bination Electrolyte in order to limit   the oxygen and hydrogen formation during charging.

Each plate of the battery uses a glass micro-fiber separator that absorbs the whole liquid electrolyte in its pore thus resulting in no free acid.

As the battery charges to its fullest, the oxygen produced at the positive plate moves via the pores of the separator to the negative plate.

Initially it reacts and forms , i.e., Lead Sulphate, then on further charging it gets converted to Pb, i.e., lead.

Due to this, the negative plate is not able to reach the correct potential in order to liberate hydrogen, and hence no water formation takes place.

Thus technician B is correct.

jupiter

explanation:

it is so massive and has such a strong gravitational pull its likely prevented the formation of a planet between itself and mars in the asteroid belt
