temperature and/or install a temperature compensation device
that adjusts rectifier float voltages in response to high battery
temperature.
Battery temperatures above 77°F (25°C) decrease battery life
while increasing battery capacity. For battery temperatures
lower than 77°F (25°C) the capacity will decrease, but battery
life will not be adversely affected. Battery temperatures within
the same string must be maintained uniformly.
When batteries are installed where they will be exposed to heat
radiation or direct sunlight, provide shields for the radiators or
blinds for the windows to maintain a low battery temperature. In
particular, the top row of a multi-tiered stand is apt to have a
higher environmental temperature than the bottom. Where
necessary, use fans or other means of ventilation to minimize the
temperature variation.
Mixing
Batteries in a
String
As batteries age, their characteristics change. As a general
practice it is not recommended to mix new batteries with older
batteries in a string. A weak battery in a string can cause the
entire string to fail prematurely.
Note
Lucent Technologies strongly recommends a temperature
compensation device in high-temperature environments.
Failure to use such a device may result in high battery
temperature that can cause premature battery failure and may
reduce or void the warranty.
Caution
Operating Lucent Technologies Enhanced VR batteries for
any significant interval of time outside the recommended
voltages and/or temperatures will cause reduced performance
and premature failure and may reduce or void the warranty.
Note
To insure maximum battery performance, do not mix
Enhanced VR Series batteries and non-VR batteries in a
string.
