Battery problems – Manufacturing Faults

Brief circuit/dead cell

Typically seen in a battery with a short (less than 12 months) lifespan. A single cell will show a drastically lower specific gravity (SG) reading than the others. The afflicted cell will boil visibly under a high rate discharge test. In some cases it may also be obvious as a sulphated cellular. 26650 battery

The remaining cells shows a good SG reading of 1. 26 or over.

Internal Break 

The battery will have good SG readings but no voltage.


Provided the right battery, in the right condition is employed for the right application, the amount of battery problems encountered will be minimum. All power packs have a finite expected life, which is governed by the conditions under which the battery operates. Battery pack failures caused by sulphation, wear and tear, or deep cycling are not manufacturing faults and are not have the company.

Battery problems – Non-manufacturing faults


When an electric battery is allowed to hold out in a discharged express for an excessive amount of time, a response takes place, which can permanently impair performance – this is sulphation. Sulphation is visible as a fine white/grey coating on the plates. Generally this indicates irreversible damage and the battery are not serviceable. This kind of damage can happen either in storage or if the battery is installed in a vehicle (or equipment) that is not used for a period of time, for example a tractor, motorcycle, or boat. Even a car or truck that is stored with the battery pack linked can still destruction the battery in this way. This is because there may be a long lasting drain on the battery from the clock, alarm etc. Seeing as a result the level of charge in a battery falls, and after a time frame sulphation will build up on the plates. The sulphation (lead sulphate) hinders the chemical reaction involving the acidity (electrolyte) and the working mass (lead compound) in the plates and inhibits the battery from functioning as normal. This is simply not a manufacturing fault.

Incorrect app

The batteries recommended are those equal to or above the original equipment specification. Fitting a smaller or less powerful power supply will cause a not as long service life and previous failure, which will generally present itself as deep cycling/premature damage. This is not a manufacturing problem.

Wear and Tear

During the charge and relieve cycle, material from the battery plates (active mass) is in motion, through the electrochemical reaction that produces electricity. Every time the battery goes through a charge and relieve cycle, a tiny amount of the active mass is lost from the china. Because the ultimate life of a battery is determined by so many factors, it is impossible to state a minimum/maximum life span. This technique of normal maturing through the charge and discharge cycle will eventually cause the battery to lose capacity, and it will come to the point where the battery pack can no longer start the vehicle/equipment. This is not a manufacturing mistake.

A battery only has a finite volume of periods (x) it might be through before it loses it is capacity to perform. Automobiles with high use such as taxi’s, minicabs, pickup trucks, and buses will often subject the battery to its x number of cycles but over a much shorter time. Seeing as a result, batteries on these vehicles can screen the above symptoms after 12-24 months. This is simply not a manufacturing fault.

Deep bicycling

As mentioned above, each and every time a battery goes through a charge and relieve cycle a tiny amount of the material from the plates is lost. In the event a battery is exposed to deep discharging (i. electronic. over 40%) and then rapid charging, this process is accelerated. Additionally, if throughout the recharge the battery pack is not adequately paid for the discharge pattern, the battery will quickly exhibit lack of performance. Including after recharging the volt quality will be low (under 12. 4v) but the cells will generally give even readings. This is simply not a manufacturing fault.
