## Overview

The 1250 Watt Ultimate Car Audio Charge Tank is a 12V 50Ah AGM battery engineered for high performance and durability. Featuring heavy-duty lead-tin alloy grids and advanced gas recombination technology, it offers leak-proof, maintenance-free operation with an 8-10 year lifespan. Its ultra-low self-discharge rate and safety valves make it a reliable, safe choice for powering demanding vehicle audio systems and accessories.

## Description

The heart of the VMAX is the unique physical and chemical structure of its plates. The special treatment and manufacturing process they undergo gains them unique reliability, strength and high performance far exceeding those of other BP-Ca plates used in similar looking products. Using our specially designed Absorbed Glass Matt (AGM) between the VMAX plates, adds to it many physical and electrical advantages that make it superior to the Wet Lead Acid Batteries. This also maximizes the VMAX resistance to shocks and vibrations. Since the electrolyte is totally absorbed by the AGM, the VMAX is classified as "non-spill able and non-hazardous". A tough Tank seals and protects the tightly packed plates delivering the VMAX in a 100% maintenance-free package. Though VMAXTANKS are best known for their long life span, their capability to recover after repeated deep discharges is what makes them the favorite choice for any application. VMAXTANKS have an expected life span of 8 to 10 years in float service applications. The self discharge rate of the new VMAX tanks at room temperature is approximately 1-2% of rated capacity per month (compared to 2-3% for most other AGM batteries and 15-20% for Lead Acid batteries). VMAXTANKS Ultra Low Resistance make it up to 99% efficient (compared to 85-95% as in Lead Acid Batteries and 97% in most other GEL and AGM batteries).

## Features

- Heavy duty lead tin alloy grids provide an extra margin of performance and service life in all applications, even after repeated over discharges. VMAX delivers the highest number of discharge/recharge cycles.
- The unique construction and sealing techniques of VMAX tanks guarantee leak proof operation with no adverse effect to capacity or service life. VMAX tanks are classified as non-spill able, non-hazardous, dry batteries.
- VMAX tanks incorporate a built-in design that controls gas generation and induces recombination of more than 99% of gases generated during usage. Completely Maintenance Free Operation.
- All VMAXTANKS are equipped with safety release valves, designed to operate between 0.98-196.1kpa and automatically reseal. Hence, there is never an excessive accumulation of gas within the battery.
- VMAX tanks utilize an electrolyte suspension system consisting AGM (Absorbed Glass Matt) of a high porosity that totally absorb and contain the electrolyte. No silica gels or any other contaminants are used.
