Advantages |
Disadvantages |
| Lead
and Oxide electrodes |
Very
cheap |
Deteriorates
quickly |
| |
Widespread
maintenance, Supplies high output, under emergency overload
easy to repair or rebuild, good scrap value |
Fumes
during charging and corrosive and explosive needs frequent
water, freezes readily when discharged, vibration shortens
life |
| Nickle
Oxide, Iron |
Long
life, little maintenance |
Requires
lot of place |
| Nickle
Oxide |
Withstands
neglect |
Very
costly, short life |
| Cadmium
electrodes and KOH electrolytes |
Maintenance needs little water, does not freeze, withstands
vibration |
Very
small market |
| Silver
oxide, zinc and KOH |
Very
high energy / unit volume |
Very
very costly, short life |
| Silver
oxide, cadmium and KOH |
High energy / vol., withstands free cycling |
Costliest
than above, limited operating life |
