Batteries can be used as both a buffer and an independent power source
Deep Cycle batteries, also known as deep discharge batteries, are an indispensable solution in many fields. Their versatility makes them applicable in various areas where reliable and long-lasting energy supply is needed.
The first application is in backup power systems: from UPS power supplies to alarm systems.
Another area of their use is in the marine industry: motorboats, electric boats, sailing yachts, and others.
Next, we have:
- photovoltaic systems,
- campers, caravans, forklifts,
- large toys.
What distinguishes Deep Cycle gel batteries is their ability to undergo multiple deep discharges and recharges without loss of performance or durability. To provide you with a stable and safe power source, we offer Qoltec Deep Cycle Gel batteries, so choose the variant that best suits your needs.

Deep Cycle technology allows for deep discharge of the battery
The battery is designed according to the latest Deep Cycle technology, which allows for deep discharge of the battery before the recharging process.
This is possible thanks to the combination of the advantages of the solution, such as gel electrolyte and thicker battery plates. This provides greater capacity, durability, and stability of the battery.
High-quality lead and sturdy ABS casing ensure long battery life
An additional advantage of our batteries is their maintenance-free designed lifespan of 10 years under optimal operating conditions!
This is possible thanks to the use of the highest quality components, including pure (non-recycled) lead. It is free from any impurities that could reduce the battery's capacity. Meanwhile, the housing designed with high-quality ABS plastic aims to maximize the battery's lifespan by protecting its interior.
However, to maintain their optimal condition, it's important to adhere to appropriate charging and storage practices. After all, when reliability and durability matter, there's no better choice than Deep Cycle batteries.
No compromises in designing our batteries with concern for the environment
Someone might ask: how do batteries containing large amounts of heavy metals, such as lead, contribute to environmental protection? There is a simple answer to this. The more we focus on creating high-quality products, the longer their lifespan becomes. Consequently, you will replace them less frequently.
In certain matters, compromise is simply not an option.
The construction advantages include maintenance-free, tightness, and shock resistance
Feel safe – the unquestionable advantage of Deep Cycle gel batteries is their complete maintenance-free operation, and their reliability is maintained for a long time. This is possible thanks to the construction characterized by:
- housing tightness,
- shock resistance,
- possibility of mounting in different positions.
By purchasing a 150Ah Deep Cycle Gel battery, you receive full reliability guarantee. Do you want your equipment to work at full throttle without limitations? Now you can be sure that it will receive the necessary energy without compromises.
Proper battery usage requires correct charging and storage
Remember that proper usage and care for Deep Cycle Gel batteries are crucial for their lifespan. To enjoy their long life, try to:
- maintain proper charging,
- avoid very low temperatures or prolonged exposure to high temperatures,
- use a charger suitable for the specific type of battery.
It is recommended to use a dedicated charger for the battery
Deep Cycle batteries require charging using the so-called constant voltage method, initially with direct current, and then maintaining a constant voltage.
This way, you can avoid the risk of damaging it due to improper charging.
Product covered by a 24-month warranty
You care about the quality of the product you're purchasing, which is why our designs and solutions are aimed at meeting your expectations. Each battery offered by us is covered by a warranty for 24 months from the date of purchase.
Complaints will be considered only if accompanied by a usage protocol, which is an essential element for the proper analysis of the report and the assessment of the claim's validity.
