Reliability of an engine depends also on battery efficiency. The most reliable battery is the one which works incessantly giving the maximum of its performances accordingly to the vehicle demands.
Co. NBA satisfies more and more numerous customers requirements, producing batteries with first-quality materials and using advanced assembling process.
In this way, batteries we produce are able to meet all needs of up-to-date cars, even in hardest conditions.
NBA complete range of batteries includes all various applications: motorbikes, cars, trucks, tractors, buses, vehicles for ground movement, fishing-boats, but also forklifts, industrial scrubbers, sweepers, etc.
These are the reasons for which most people choose our products.


Storage rules
Batteries must be kept in dry places and, if possible, with no changes of temperature.
They don't have to be exposed in shop-windows at sunlight.
Although up-to-date construction technologies have reduced self-discharge, it's always advisable avoid long warehouse stocks for wet batteries.
Before to set a battery on vehicles, it's better carry out a "refreshing" charge (to obtain better efficiency from battery).
Dry charged batteries can be stored for long periods, without any danger of damaging. Longer will be the storing period, longer should be the activation charge.

Activation of dry charged batteries
Remove caps and fill all cells with electrolyte till about 10 mm on separators edge (see the higher level stamped
on box).
Electrolyte is a solution of sulfuric acid for batteries, which gravity is 1,275 gr/lt + 31 Bè.
To obtain a good activation, acid and battery should have a temperature higher than 15 °C.
Let the battery rest for about 30 minutes, check acid level and - if necessary - fill up with some more electrolyte.
Replace caps and clean the battery cover.



Before to set battery on vehicle, make sure that battery is well charged. Fix correctly the battery in its spot on the vehicle, avoiding to screw too much and damage the box.
the clips and tighten them deeply on the poles, strewing them clean with vaseline or other neutral products.
Removing the old battery, first unscrew the eartn clip. Setting the new one, last connect the eartn clip.

State of charge
Battery state of charge can be verified by checking electrolyte gravity.

State of charge
Electrolyte gravity
gr/lt 1.275
gr/lt 1.240
gr/lt 1.210
31 Bè + o more
28 Bè
25 Bè

Batteries which gravity is less of 1,210 gr/lt + 25 Bè have to be charged immediately.

Do not use fast chargers. Connect correctly battery with charger, so to avoid damages to the equipment.
Charge with current of 1/10 capacity in Ah (i.e. Battery of 50 Ah has to be charged with 5 Ah).
Charge can be considered ended when there will be a lively gasification inside electrolyte and gravity will be at 1,275 gr/lt + 31 Bè, these two last conditions will remain the same for at least 2 hours.

Safety warning
To prevent danger of incidents, it's necessary pay attention to the following points:
A - Electrolyte contained inside batteries is a sulfuric acid solution, therefore a corrosive material. In case of contact with skin, eyes, clothes or painted surfaces wash immediately with abundant water. Concerning eyes, medical cares are useful. Keep out from children's reach.
B - Batteries generate explosive gas. In order to prevent danger of explosion, do not approach batteries with flames, cigarettes, and do not generate sparks during operations of setting, removing, checking and starting with false connections through batteries or auxiliary equipments. When a battery have to be charged, pay attention to the correct connection of polarity with charger, carrying out safe connections which avoid sparks and avoiding to use too high currents of charge.
If charge process takes place in narrow places, provide a suitable ventilation.
