4.4.1 Temperature

Avoid placing batteries in areas of high temperature or

in direct sunlight. The optimal temperature range for

performance and service life of the Genesis

battery is

20ºC to 25ºC. These batteries can, however be used at

temperatures ranging from -40ºC to 80ºC when fitted

with a metal jacket.

4.4.2 Ventilation

As stated before, under normal operating conditions

the gas emission from Genesis batteries is very low.

Natural ventilation is adequate for cooling and to

prevent buildup of hydrogen gas. This is why Genesis

batteries may be used safely in offices, hospitals and

other occupied environments.

When installing batteries in cabinets or other

enclosures, care must be taken to ensure they are not

sealed enclosures. UNDER NO CIRCUMSTANCES

SHOULD THESE BATTERIES BE CHARGED IN A

SEALED CONTAINER.

All installations and ventilation must comply with

BS 6133 or EN 50272.

4.4.3 Mounting

Check that all contact surfaces are clean before

making the interbattery connections.

Tighten the screws to the recommended torque value

using insulated tools only and follow the polarities of

individual batteries to avoid short circuits. Finally,

connect the battery end terminals.

Since the Genesis battery has all of its electrolyte

immobilised in its separators, it can be mounted on its

sides without any performance degradation.

Note: The safety standards of EN 50272.

4.4.4 Torque

The recommended terminal torque for the full range is

given in Table 4.4.5.1. A loose connector can cause

problems in charger performance, erratic battery

performance, possible damage to the battery and even

personal injuries.

Only use insulated tools when working on batteries.

Table 4.4.5.1: Terminal torque values

4.5 Parallel strings

While there are no theoretical limits on the number of

parallel battery strings, we recommend no more than

6 parallel strings per system, particularly for cyclic

applications.

4.6 Discharging

It is strongly recommended that a low voltage cutoff be

included in the battery load circuit to protect the battery

from overdischarges. The setting for end of discharge

voltage (EODV) is dependent on the rate of discharge,

as shown in Table 4.6.1. For optimum battery life, we

recommend that the battery be disconnected from the

load when the appropriate voltage is reached and put

back on charge as soon as possible after a discharge.

Table 4.6.1: Suggested battery cutoff voltages

Note:

Discharging the Genesis battery below these

low voltage cutoff levels or leaving the battery

connected to a load in a discharged state may impair

the battery’s ability to accept a charge.
