Figure 6 Battery Voltage and Current During Recharge
If the ALM 12V7 s-Series battery has entered an Under Voltage Protection (UVP) state, the
battery disconnects from the load. Connecting a charger to the battery resumes normal
operation based on replenished energy.
NOTE
New batteries may be used as received. However, to ensure that all cells are balanced and fully
charged before their first use, individual batteries should be charged for 4 to 24 hours with a float
charge. Charging is particularly necessary prior to performing capacity tests. After initially balancing
the batteries, normal use should maintain the cells in a proper state.
REMARQUE
Les nouvelles batteries peuvent être utilisees tels que reçuss. Cependant, our s'assurer que tous les
elements de la pile sont équilibrés et pleinement chargés avant leur première utilisation, les
batteries individuelles devraient être chargées pendant 4 à 24 heures avec une charge de maintien.
La charge est particulièrement nécessaire avant de procéder à des tests de capacité. Après
équilibrage d'abord des piles, l'utilisation normale devrait maintenir les elements de la pile en bon
état
.
Charge Limits and Temperatures
At room temperature and above, ALM 12V7 s-Series batteries can accept full rated charge.
As with all battery technologies, charge acceptance is limited at low temperatures. A
permanent loss of capacity over time may be observed if charge rates are not reduced at low
cell temperatures. As the cells’ temperature rises during the charging process, they can
gradually accept higher currents.

maximize battery life.
