Traction batteries

Panzer Batteries Type PzS The Pzs batteries have the typical positive plate structure – a grid structure whose metal parts are each encased in a plastic tubular separator, into which the active material is supercharged under high pressure. This new structure significantly increases the battery life and enhances its technical performance. The Pzs batteries are manufactured in different versions:

- The Pzs battery components are joined with bolt type or flexible connectors

- The central collection of gases, as well as the electrolyte charging is done according to the requirements of the user.

Advantages of the “ISKRA” battery:
– Low price and high technical performance
- Battery life up to 1500 charge/discharge cycles .

Panzer Batteries Type PzSL – this is a new type of traction batteries which is manufactured in full compliance with the EU standards and is in accordance with the world trends for increasing the capacity of batteries while at the same time decreasing their overall dimensions. If the overall dimensions are preserved the same, the battery capacity increases by at least 10% due to the new structure of a 2 V PzSL element, in which the positive plates constitute a grid structure, each component of which is encased in a new type of special tubular separator, which allows for increased active mass/substance, which in turn increases the battery capacity. The PzSl elements connected in a series are encased in a metal box with anticorrosive or ebonite coating. The increased capacity PzSL traction batteries are manufactured and delivered in several different versions:

- PzSL elements joined with bolt type or flexible connectors

- The central release of gases, as well as the electrolyte charging is done according to the requirements of the user

Advantages of the increased capacity PzSL traction batteries “Iskra” battery:
- Low price and high technical performance.
- Battery life up to 1600 charge/discharge cycles, longer operation times between chargings

Increased capacity Panzer Batteries Type PzSH – a third type of traction batteries. Similar to the PzSl type, here again the capacity is increased although the overall dimensions remain the same, this time by at least 20%, due to the special structure of the 2 V elements. This additionally increases the battery life and the operation periods between chargings. Analagous to the PzSL type, the PzSH batteries are also available in different versions.

  • During the entire technological process of production of each of the semi-manufactured goods, the necessary parameters are strictly monitored by up-to-date technology and highly qualified staff
  • The traction batteries are incased in metal cases with a unique plastic coating, specially designed for "Elhim-Iskra" JSC, which withstands all aggressive impact under heavy-duty applications.

Designation of the Panzer battery types

A two- 40-V-cell battery with 210 Ah capacity

2 40V x 3 PzS 210 -b:

  • 2 – number of cells
  • 40 – voltage in one cell (V)
  • 3 – number of positive plates (еlectrodes) in the battery
  • PzS – type of element (tubular positive electrode/coated positive plates)
  • 210 – nominal power(Ah)
  • -b – flexible connector


Main characteristics of traction batteries

Battery warranty: 18 m
Run time: 1500 cycles for a charge

The lead-acid batteries/accumulator batteries/ consist of lead traction elements joined in a series and encased in a metal case with acid-resistant coating. The batteries are manufactured in two versions depending on the type of attachment to the transport vehicle: with 2 or 4 pole terminals with the designation “+” or “-”.

The following types of batteries can be manufactured on demand:

1. With conical terminals in compliance with BDS БДС 3974-73;

2. With terminals in compliance with DIN 43596;

3. With another type of terminals /as required by the customer/

The metal cases are designed with suitable openings for loading and unloading operations, and some have special grooves for attaching the battery to the electric truck or fork lift truck. The volume of the traction battery depends on the volume of the traction elements which constitute it

The ISKRA traction batteries have a capacity of 165 - 960 Ah and comply with BDS EN 60245-

1. The nominal capacity is the battery’s capacity in 5-hour discharge mode Аh - С5. The discharge current is IR=0.2*С5(А). All traction accumulators consist of a set of positive and negative plates divided with separators. The set is assembled in a plastic box sealed with a lid. The traction batteries are manufactured in two versions, the difference being that the pole terminals are connected with a flexible or bolt connection in the battery. The terminals coming out of the lid are sealed with rubber seals and special screws. In the middle of the lid there is a ventilation lid which ensures the free escape of gases during work and prevents the direct release of sulphuric acid aerosols. The ISKRA battery structure allows for replacing faulty elements with new ones of the same type.
