FIAMM AGM Valve Regulated Recombination Batteries: FLX Series- Engineering Manual

Connection of the battery to the rectifier/load

The end positive terminal of each string of batteries should be connected to the positive terminal of the

charger, and the battery negative to the charger negative. Same procedure needs to be used for load

connections. A proper selection in cables and connectors should be used to avoid excessive voltage

drop, as well as overheating in case of high rate discharge. If a large section of cables are used their

weight should not stress cell/block terminals. A good method to use is to affix cables on the rack or the

nearby wall.

3 CHARGING

Introduction

After installation, in order to ensure the best protection against power failures, it is necessary that

batteries are kept in the following conditions:

• float charged throughout their standby period;

• fully recharged soon after a discharge.

Recharging process can be performed in several ways, depending on the site and equipment

conditions, but there are two main methods:

• float voltage recharge

• boost charge

The IU recharge method, also known as the modified constant voltage recharge, has been used for

many years and in a variety of applications. This method combines the need to have the battery quickly

recharged while ensuring maximum battery life. With this method, recharge starts at a constant current

rate. The voltage increases up to a pre-set value. The pre-set voltage is maintained and the current

then decreases to a minimum defined value. Finally, the recharge is completed at a final constant

voltage value equal to or less than that defined for float charge with the current decreasing to the value

used in float.

•

For UPS systems that do not utilize a constant float voltage charging profile or use an

Advanced Battery Management charging profile please set the charging parameters per

table 3.

Recommended procedure for initial charging

For a safe installation of FIAMM FLX batteries only constant voltage chargers should be used.

The best charging method operates with a preset constant voltage value supplying an automatically

limited charging current. It is called constant voltage charging with current limit and automatic

crossover.

An initial charge of 2.35 to 2.40 volts per cell for at least 24 hours (at 77° F) is suggested during

commissioning or before a capacity test in order to be sure that the battery is in fully charged condition.
