4.3. Ripple

Residual AC ripple is usually present in the output

voltage of chargers; amplitude and frequency depends on

charger design and it can affect negatively the battery

life.

Ripple

could

temperature and accelerate corrosion with a result to

reduce the battery life. It is recommended therefore, that

voltage regulation across the system including the load,

but without the battery connected, under steady state

conditions, shall be better than ± 1 through 5% to l00%

load. Transient and other ripple type excursions can be

accommodated

provided

disconnected but the load connected, the system peak to

peak voltage, including the regulation limits, falls

within 2.5% of the recommended float voltage of the

battery. Under no circumstances should the current

flowing through the battery when it is operating under

float conditions, reverse into the discharge mode.

4.4. Battery room requirements

 The battery room should be dry, well ventilated and

have its temperature as moderate as the climate will

allow, preferably between 10°C and 30°C.

 DO NOT permit smoking or the use of open

flames in the battery room.

 Adequate ventilation to change the air in the battery

room is essential to prevent an accumulation of the

gases given off during charge (for further information

please refer to "VENTILATION" paragraph).

 The battery will give the best results and life when

working in a room temperature of 20°C (FHT range

can satisfactory operate at higher temperatures). High

temperatures increase the performance, but decrease

the life of the cells; low temperatures reduce the

performance.

 Do not allow direct sunlight to fall on any part of the

battery.

 If a rack is not supplied by FET, suitable racks should

be provided to support the cells. These should be

arranged to provide easy access to each cell for

inspection and general maintenance. Suitable racks

may be made of wood or metal with a coating of acid

resistant paint. If metal racks are used, they must be

fitted with rubber or plastic insulators to prevent the

cells coming into contact with the metal.



To facilitate proper battery operation, maintenance,

and care, post a battery data card/ instruction table in

a conspicuous place near the battery to provide the

attendant with service information and data.

SAFETY

It is recommended that full precautions be taken at all

times when working on batteries. The safety

standards of the country of installation must be risk,

explosives gasses, heavy components,

5.1. Protective Equipment

Make sure that the following equipment is available to

personnel working with batteries:



Instructions manual.



Tools with insulated handles.



Fire extinguisher.



PPE (Personal Protective Equipment) must be worn

(glasses, gloves, aprons etc ...). To avoid static

electricity when handling batteries, material of

clothing, safety boots and gloves are required to have

a surface resistance ≤ 10

resistance ≥ 10



First aid equipment must be available

5.2. Safety Precautions

Observe the following precautions at all times:

 Batteries are no more dangerous than any other

equipment when handled correctly



Do not allow metal objects to rest on the battery or

fall across the terminals (even when disconnected, a

battery remain charged!).



Never wear rings or metal wrist bands when working

on batteries.



Do not smoke or permit open flames near batteries or

do anything to cause sparks.



Do not try to remove the battery cap to add water or

acid into the cell(s).



Never lift or pull up the battery at the terminals.

 Air exchange must be provided to prevent the

formation of explosive hydrogen concentration.

 For further information please refer to EN 50272-2

Safety requirements for secondary batteries and

battery installations Part 2: Stationary batteries.

5.3. Battery Disposal

Lead acid batteries must be disposed according to the

country law. It is strongly recommended to send batteries

for recycling to a lead smelter. Please refer to the local

Standards for any further information; these batteries

need to be collected separately for waste disposal. As of

the 31

December 1994, all Valve Regulated Lead Acid

(VRLA) battery has to have the following symbols

present in conformance to EG-guideline 93/86/EWG

Edition 03/2018 Rev.7
