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

Ventilation in battery room

Under normal operating conditions, the gassing rate of FIAMM FLX Series batteries is extremely low.

However, the battery room should have sufficient ventilation to avoid temperature rise in the event of

unexpected circumstances such as overcharge due to a charger malfunction. As accelerated

recombination reaction generates heat, it is important that there allowances in ventilation to dissipated

excess heat through ventilation or air conditioning.

Temperature control in battery room

Battery life and performance are optimal at a temperature of 77° F. Operation at lower temperature will

reduce available capacity (for the period of time that the battery remains at low temperature). Higher

operating temperatures affect battery performances and will shorten the battery service life. Air

circulation within the battery room must be sufficient to avoid hot or cold spots. The total temperature

spread between the hottest and the coldest cell of the same string should be maintained inside a

window of +/- 5° F.

Racks

Battery racks should be grounded and made of acid resistant and insulated material. For safety reasons

they should be installed as level as possible. The depth and the height of the racks, along with servicing

headroom, should allow both adequate ventilation and a satisfactory servicing.

Cabinets

Good ventilation is extremely important for battery cabinets. Ventilation openings should be both at the

bottom of the cabinet, and as close as possible to the top, to prevent any hydrogen accumulation in an

abusive situation. Cabinets should be placed/fastened steadily to the floor.

Installation procedure

For a proper installation clean the blocks with a soft dry antistatic cloth or soft water-moistened cloth.

Place each cell/block at their correct position according to the electrical layout. Start with the lowest

shelf to ensure stability. Inter-tier and inter-row connections should be applied only once all blocks have

been connected properly. For proper ventilation and airflow maintain a distance of .25" or greater

between all battery blocks.

Interblock connecting procedure

It is extremely important to ensure proper surface contact between battery terminal posts and cables

(recommended) or solid connectors used to complete each string. Each connecting surface must be

clean and without oxidation. If required use very fine grit abrasive paper to remove any dirt on each

surface. Do not use wire brushes or similar tools that may damage the plating film around terminals' and

connectors' copper. Then apply a light coating of No-Ox grease to the terminals and connectors prior to

installation of the connection hardware.

Terminal torque settings

To ensure a proper electrical connection between the flat surface of each terminal and the connector a

calibrated torque wrench must be used. Torque the electrical connections to the settings in Table 2.

Final checking of connections

To perform a final check of the connections it is advisable to measure the overall battery voltage and

make sure that this value is equal to the open circuit voltage of an individual block multiplied by the

number of blocks.

Paste a sticker with a progressive number to each block, making sure that the surfaces are dry and

clean. It is a good practice to number the blocks beginning with #1 at the positive end of each string.
