Maximize Battery Charger

MAXIMIZE YOUR LIFT’S BATTERY CHARGE PROFILE

In the same way, that different deep-cycle battery designs vary in capacity and overall performance, charging the battery can be as unique as the battery itself. Because deep-cycle batteries in various vehicles and machinery can differ in their work environment, the battery’s capacity and performance are susceptible to how they are charged and maintained. Battery manufacturers like U.S. Battery work with charger manufacturers such as Delta-Q to develop various charging profiles for particular battery sizes and designs to maximize your lift’s battery performance. Ultimately, the overall performance of any work platform comes down to how well the batteries are maintained, the depth of discharge, and the “charge quality” during each recharging session.

According to Delta-Q, the manufacturer has more than 50 charge algorithms on hand for a variety of batteries. To determine how to give your equipment’s battery the best charge, you need to understand what charge algorithms are. There are different charge algorithms available on many battery chargers, but to understand this, you first need to know that there are basically three stages of battery charging. The first is a Bulk Stage, where the charger uses constant current at full charger output to bring the battery to approximately 80% state of charge. The second stage is Absorption Charge using constant voltage where the charge current tapers from full charger output to a lower level that depends on battery conditions. The charger allows the battery to control the charge rate at which it can accept a charge until 100% of the amp-hours removed on the previous discharge are returned. At this point, the battery is not quite fully charged and requires a controlled overcharge. The third stage is the Finish Charge, where the charger gives the battery a lower constant current charge at a charge rate that is proportional to the design capacity of the battery. Assuring the battery is fully charged and provides enough gassing to mix the electrolyte to prevent electrolyte stratification.

During these three charge stages, charge algorithms can differ in current, voltage, time, and amount of overcharge. Charge algorithms are adapted to optimize charging for specific battery models and chemistries. To begin with, there are three primary types of algorithms. SPECIFIC charge algorithms that are custom designed in collaboration between the charger manufacturer and the battery manufacturer and are used by most Original Equipment Manufacturers (OEM) of access lifts and machinery. For performance and warranty reasons, lift OEM’s use a specific battery and therefore require a particular charge algorithm to maximize the battery life for the performance and use environment of the equipment. Depending on the battery chemistry and its use, the charge time and current applied during these three stages can vary to provide the best possible balance between cycle life, runtime, and overall battery life.

Some charger manufacturers use GENERIC charge algorithms designed for particular battery chemistries (such as flooded lead-acid, AGM or Gel) and a wide range of amp-hour capacities. Each chemistry requires a different charge algorithm and amount of overcharge. According to charger manufacturer Delta-Q, a generic charge algorithm will provide a reasonable compromise between battery life and performance. Generic algorithms provide greater flexibility between battery makes and models, especially if the owner decides to change to a different battery when it’s time for the battery to be replaced.

Some charger manufacturers offer UNIVERSAL charge algorithms that can be used for all types of batteries, and most battery manufacturers do not recommend the use of these algorithms. If used, battery state of charge and temperature should be carefully monitored to prevent undercharge or overcharge that could severely decrease battery performance and life.

Ultimately, the best way to get the most out of your batteries, and your lift equipment, is to consult with the manufacturer and/or look up the charge algorithm they have for the specific battery in your equipment. The battery charger should use that specific charge algorithm; allowing you to get the most out of your batteries and ultimately your equipment.

5 Benefits To Using A Single Point Watering System

Anyone using deep-cycle flooded lead-acid batteries in their electric vehicle or other equipment knows the importance of routinely watering the batteries. During charging, the water content of the electrolyte will decrease due to the electrolysis of water into hydrogen and oxygen gases. If left unchecked, the electrodes inside each cell can become exposed, resulting in a loss of battery performance. Regular watering is essential to the continued life and performance of any flooded deep cycle battery.

Electric vehicles and other equipment using deep cycle batteries typically have from four to eight individual batteries – each with multiple cells. Watering each cell can take a significant amount of time, especially if you are maintaining a fleet of vehicles. Battery packs are often located in areas that are not easily accessible, increasing the time required for watering.U.S. Battery offers two single-point watering systems (SPWS), Battery Watering Technologies and Flow-Rite, which can make battery maintenance quick and easy while offering several other benefits.

  1. You Can Fill All Your Batteries At Once
    A SPWS connects to all of the cells in each of the batteries within the pack allowing you to fill them with water from a single point.
  2. Save Time During Regular Maintenance
    On a single battery-powered vehicle, you can water all of the batteries in about a minute, versus what would normally take 45-60 minutes per vehicle.
  3. No Chance Of Over Watering
    With an SPWS, the battery cells fill up to the proper level and shut off to prevent overfilling.
  4. Monitoring Systems Can Tell You When To Water
    Some SPWS offer a sensor that can monitor water levels in the battery and indicate when they need watering.
  5. Extended Battery Life
    Frequent maintenance extends the life of your batteries which in turn lowers your annual operating costs.

Ladder/Stool fall injuries, in the U.S., requiring medical treatment in 2017

Ensuring employee safety is an ongoing concern, causing many employers to look at the use of traditional ladders and scaffolding in the workplace. These growing concerns have in turn led to an increase in demand for compact vertical lifts and smaller scissor lifts. An article in the May-June 2018 issue of Access, Lift & Handlers Magazine reported that vehicle manufacturers such as JLG, Skyjack and, Snorkel are making smaller, more compact vertical mast lifts and scissor lifts in response to the industry’s call for greater safety for workers who would normally use ladders and scaffolding on jobs of 18 to 25 feet.

These low-level lifts feature smaller footprints, tighter turning radiuses, and are lighter than typical Aerial Work Platforms. They are available in manually operated or self-propelled models, allowing them to access areas that would be difficult or impossible for other lifts. The Skyjack SJ12 & SJ16, for instance, have a zero inside turn radius and only weigh 1,720lbs. and 2,130lbs, respectively. And, they only need four 6v deep cycle batteries, like the US2200 XC2, to supply the necessary 24V for operation. Due to their versatility and stability, construction crews, facility managers, and consumers are quickly adopting vertical mast lifts; as a way to reduce the risk of injury on the job.[/vc_column_text][/vc_column][/vc_row]

Getting More Power From Your Aerial Lift

Replacement Batteries For Aerial Lifts

When working on a job site it is necessary for equipment operators to get the most battery life out of your scissor lifts.  High-quality Deep Cycle batteries can provide you with years of reliable cost efficient power.  Choosing the right batteries and properly maintaining them is crucial to get the most out of your lift.

Picking the Correct Battery

When selecting a replacement battery it is important to refer to the lift manufacturer’s specifications.  Most lifts use either 6V or 12V batteries, but not all batteries are able to supply sufficient power for every lift. The size of the lift, its lift capacity, and the lift’s intended application help determine its power requirements.

For Example:

  • JLG’s ES Series and R Series scissor lifts utilize a 24V system requiring four 6V batteries with a minimum rating of 220 amp-hours. Batteries like the U.S. Battery  US 2000 XC2 or US 2200 XC2 are ideal for these power requirements.
  • While the JLG LE Series scissor lifts are a 48V system and require eight 6V batteries with a minimum rating of 370 amp-hours. Making our US L16 XC2 the perfect fit for this series of lifts.
