We want car enthusiasts who buy batteries for their cars from us to be satisfied with their purchase for as long as possible.

And we know how to extend the life of starter batteries. Our experience helps us in this, because we have been working with car batteries for a quarter of a century.

We were the first in St. Petersburg to set up a workshop for warranty service and repair of car starter batteries.

Today every customer, purchasing a rechargeable battery with a guarantee from the company “Katod”, can count on qualified warranty and post-warranty service.

Corporate Service Center of the Katod chain of stores offers the following services:

To make it even more convenient for you to purchase from us:

  • Free* installation of batteries purchased from Cathode stores .

To save you trouble:

  • Free battery diagnostics
  • Battery charger
  • Removing and/or installing batteries
  • Battery rental
  • Replacing battery wire terminals
  • Correction of electrolyte level in batteries
  • Filling dry motorcycle batteries (preparation for commissioning)

Warranty service

We work only with manufacturers of high quality products. Therefore, the share of factory defects, as a rule, does not exceed one percent of the total number of batteries sold.

An examination to identify the causes of a malfunction takes an average of 5 to 10 days, depending on the workload of the Service Center, but no more than 21 days. At this time, the owner of the faulty battery is given a replacement (if available).

The task of the Service Center is not only to assess the condition of the battery and determine the cause that led to the failure, but also, if possible, to return the battery to working condition.

Post-warranty service

It is known from experience that the most common causes of battery malfunctions are:

  • improper use, including: prolonged use or storage of the battery in a discharged state
  • battery aging and failure due to normal wear and tear
  • mechanical damage

Approximately half of the cases of complaints about battery malfunctions are identified as the cause of a discharged condition. In this case, we can take a dead battery to recharge and rent a replacement so that the owner does not remain without a car.

The most demanded is the pre-season (before the onset of winter) control of the battery condition and restoration of its parameters to the nominal values ​​in order to avoid problems with starting during the winter cold.

And here is an interesting article on the maintenance and care of the battery, we recommend that you read it.


* The battery installation service is free for most car models. The exceptions are individual cases that require complex long-term work. A more detailed list of exclusions can be found here and checked with the service center masters.

UPS batteries. Classification


Content:

  • UPS battery – the main part of the UPS
  • Batteries for uninterruptible power supplies. Classification by type of electrolyte

UPS battery – the main part of the UPS

A very important part of any uninterruptible power supply is the battery. All the main parameters of the uninterruptible power supply depend on the technical characteristics of the battery for the UPS. It is the UPS battery that ultimately determines both the power of the source and the duration of the uninterruptible backup. That is why it is necessary to correctly approach the issue of choosing a battery for an uninterruptible power supply.

Batteries for uninterruptible power supplies. Type classification

Nowadays, various types of batteries are produced in the world. Here is a far from complete list: lead-acid, copper-lithium, nickel-cadmium, nickel-metal hydride, iron-nickel, sodium sulfur, silver-zinc, silver-cadmium, lithium-ion, lithium-polymer, nickel-hydrogen, manganese-zinc. All types of rechargeable batteries have different designs, different properties and different prices.
Consider the main types of batteries used for uninterruptible power supplies.

UPS Lead Acid Batteries

Lead-acid (from English Sealed Lead Acid) batteries are the most widely used. The positive properties of include: low cost, low self-discharge, high reliability, voltage stability, operation in a wide temperature range, duration of operation cycles, the ability to perform up to a thousand charge / discharge cycles. The negative properties of include: large weight and dimensions, small specific capacity, they lose their performance during deep discharges.

Nickel Cadmium UPS Batteries

Nickel-cadmium (Ni-Cd) batteries have gained great popularity in recent years due to their light weight and size, and are widely used in various electronic devices. To positive properties include: high energy density, the ability to carry out up to 1500 recharges, low self-discharge (less than 20% per month), not expensive price, high reliability, ease of operation, good resistance to temperature extremes. The negative properties of include: the presence of a “memory effect”, a gradual decrease in battery capacity, uses a highly toxic substance, high cost of processing and disposal.

Nickel-metal hydride batteries for UPS

Nickel-metal hydride (Ni-MH) batteries have been known for a long time and have a number of improved characteristics, but they are not widely used, primarily because of the difficulties in operation. The positive properties of include: high specific capacity, stable operation, high energy density, does not reduce the level of capacity. The negative properties of include: a small number of charge / discharge cycles, high battery price, a narrower temperature regime, low load capacity, does not tolerate deep discharges, a high level of self-discharge, the complexity of the charging process, high operating costs.

Li-Ion UPS batteries

Lithium-ion (Li-Ion) batteries were invented in the first half of the 20th century, but their mass production began only in the 90s. Today they are the most promising for use in electronic devices. Such batteries have a large specific capacity and can provide a powerful consumer with a small dead weight and size. To positive properties include: high reliability, high energy density (about 100 Wh / kg), very low self-discharge rate (about five percent per month), the battery does not lose capacity during operation, low maintenance costs. The negative properties of include: high price, not a sufficiently wide operating temperature range, the battery must be stored in a charged form, there is an aging effect, it is necessary to use special chargers.

Currently, the most common lead-acid batteries for UPS. The main reasons are the high reliability of batteries, low acquisition cost, ease of maintenance, performance in harsh climatic conditions, and the possibility of multiple charging procedures.

Batteries for uninterruptible power supplies. Classification by type of electrolyte

According to the type of electrolyte used, all batteries can be divided into three main groups: batteries with liquid electrolyte, batteries using GEL technology, batteries using AGM technology. Consider the main characteristics of these types of batteries.

Batteries for uninterruptible power supply with liquid electrolyte

Liquid electrolyte batteries are the most widely used. This technology involves the use of a sulfuric acid solution as the electrolyte. This type includes conventional car batteries. Their main disadvantage is that they are not airtight. During operation, such batteries emit hydrogen and sulfuric acid vapor, which negatively affects their environmental friendliness. Leaky batteries require complex maintenance, a special room for charging and maintenance work. The positive properties include the low cost of acquiring a battery. Such batteries are rarely used for uninterruptible power supplies, however, they can be used in the case of an external connection of the battery and the presence of a special non-residential premises.

GEL batteries for uninterruptible power supply

GEL batteries (gel batteries) are manufactured using GEL-Electrolite technology. To obtain the desired jelly-like state, a special thickener is added to the composition of the battery electrolyte. Batteries created using this technology do not emit gases. Therefore, they are sealed. Sealed UPS batteries are safe and require no special maintenance. GEL batteries are highly reliable, operate in a wide temperature range, have a high capacity and a long service life. However, their cost is higher than that of leaky batteries. It is also necessary to prevent deep discharge of such batteries.

AGM Batteries for Uninterruptible Power Supply

AGM (Absorptive Glass Mat) technology batteries are state of the art. In fact, they are a modernization of the GEL type battery. As an electrolyte in such batteries, a liquid electrolyte absorbed by special porous fibers is used. This technology allows you to make batteries sealed. No harmful fumes are emitted during their operation. At the same time, the electrical resistance of such batteries is lower, which significantly improves performance.
