This battery will also likely deliver its full rated capacity after 25 years of operation. Maintenance, especially watering, is low and the Plante battery can tolerate operation at high temperatures better than the various lead acid alloyed types, i.e., calcium, antimony, etc. Because this type of battery generates hydrogen gas when charging and because the sulfuric acid electrolyte does evaporate to some extent, these batteries must be used in a room which is well ventilated to the outside and kept away from delicate electronic equipment. This battery is manufactured by utilizing a lead antimony allow in the grid construction which increases the strength of the plates. Thus, special and expensive mechanical construction is not necessary.
Adequate ventilation becomes more important.
The frequency of maintenance, water addition, also increases. There is also a need for periodic monthly equalization. This battery may be selected where frequent discharging is expected. As with most UPS applications, the battery will be floating on the charger most of the time, and even when discharged, may not normally be fully discharged. This battery offers an excellent cost versus service reliability advantage.
