We offer a wide selection of modern lead-acid batteries of the VRLA (Valve Regulated Lead Acid) type, using the technology of self-regulating safety valves and internal recombination of gases. The use of valves allows for complete sealing of the battery casing and, as a result, protection against electrolyte leakage to the outside. The VRLA line includes min. VPRO, OPTI, DEEP CYCLE, GEL (gel).
AGM OPTI VRLA and AGM VRPO VRLA batteries are AGM (Absorbing Glass Matt) models where the electrolyte is completely bound in the glass fiber mat, thus protecting the battery against electrolyte stratification.
DEEP CYCLE VPRO SOLAR VRLA series batteries are built, among others, by high-density lead plates for deeper discharge and greater cycle times than standard AGM batteries. The GEL VPRO PREMIUM VRLA (gel) models with a dense gel electrolyte are very shock-resistant and achieve deep discharge without significantly affecting the battery nominal capacity.
Our batteries are widely used in, among others, photovoltaic installations, emergency power supply of central heating installations, pumps, stoves, alarm and fire installations, motorhomes and caravans, boats, yachts, etc. If you are looking for a battery that will allow you to maintain the operation of your devices as long in the event of a power failure, an AGM battery will be the best solution. In the case of cyclic operation, e.g. in photovoltaic installations, we recommend the use of DEEP CYCLE VPRO SOLAR VRLA and GEL VPRO PREMIUM VRLA series batteries. Due to their high resistance to temperature conditions, shocks and high cyclicality of operation, GEL VPRO PREMIUM VRLA batteries are the best solution for photovoltaic installations and cyclic operation systems.
In addition, we also offer an outstanding series of LiFePO4 (lithium-iron-phosphate) batteries, which are characterized by a very large number of cycles (practically 3-4 times more than with AGM / GEL batteries), long service times and low weight. An additional advantage is the built-in BMS, ensuring long-term storage of the battery without losing nominal capacity and controlling the charging and discharging processes of the battery. These batteries are best for installations where many years of trouble-free operation is required and where the batteries are exposed to longer storage by work (they have very low self-discharge). These batteries must be charged with the appropriate chargers, which we also offer (10A and 20A).
If you are looking for fast and effective charging of 6V, 12V or 24V car and motorcycle batteries, in our offer you will find a wide selection of automatic chargers of different power, among others. SMART series (with 4-stage charging cycle, multi-stage battery protection), MOBI and rectifiers with LCD display.
The small size AKU PROTECT balancers will help you maintain equal voltage on batteries connected in series for 24V OR 48V (AGM, gel). The balancer is a must in photovoltaic installations where the customer wants to maintain the efficiency of his battery bank for many years. The balancers will equalize the voltage of the batteries when they detect that the difference between the batteries is 20 mV (24V model) or 10 mV (48V model).
