Extend Battery Life with Multiple Battery Tenders

Extend battery life:

Extended battery life is usually twice the capacity of a regular battery. There are some steps to follow,  then extend your battery life.

  • Don’t keep your display too long
  • Reducing your display timeout to 30 seconds is ideal for reducing battery usage
  • Don’t let your battery completely drain
  • Don’t overcharge the battery
  • Don’t overload the equipment
  • Don’t share batteries in extreme conditions
  • Do keep the battery clean

Multiple Battery Tenders

A battery tender is a product for maintaining a car battery charge generically known as a trickle charger. A trickle charger delivers a low and steady energy stream to maintain a car battery charge during storage. Maintaining a charger helps prevent damage caused by depleting a car battery. Battery tenders release a slow trickle of energy into the battery to keep the charge up and maintain the charging capacity of the battery without overcharging

. A battery tender helps to extend the life of your battery by preventing damage to it In most cases, this charge maintenance will extend the battery’s useful life by at least 50%. some customers have reported a battery life increase of more than double what they had before using the battery tender plus or battery tender junior battery charger.

Working of Multiple battery tenders:

Connect to a heavy gauge metal part of the frame or engine block. for a positive grounded vehicle connect the negative black clip from the battery charger to the negative (NEG N,-) ungrounded post of the battery connect the positive red clip to the vehicle chassis or engine block away from the battery Battery tender bank chargers fully automatically switch their output voltage to a safe storage or float level eliminating the need to constantly check the conditions of the battery and provide zero to minimal current draw.

Maintaining optimal charge level of Multiple battery tenders:

Most battery tenders battery chargers have float voltages between 13.3 and 133.5 volts. Your Path to Enhanced 12 AA Battery Efficiency The important this is that the float voltage should be higher than the fully charged rest state battery voltage and it should be lower than the gassing voltage which is about 13.8 8 volts. it is best to charge your battery to 80% to 90%. Aim to keep the battery level between 20% and 80% whenever possible.

This is because the charge level corresponds to the number of moveable lithium ions in the graphite and lithium cobalt oxide layers of the cell. The battery will take 6 to 8 hours for the green light to come on. the battery tender plus can continue to supply its full current even after it has switched over to the lower float maintenance charge voltage of 13.2 volts. Applying a top-up charge also referred to as a maintenance charge will help prevent sulfation building up. Sulfation is the number one reason you should not store your lead acid without charge.

This process causes the degradation of the battery, which shortens its useful life based on the efficiency of the process that more than then70% of batteries discarded are due to sulfation. The effect of insulation is the accumulation of crystal of lead sulfate PbSO4 which implies battery usage time is reduced


Mukti-Bank Charger: A multi-bank battery charger is specifically designed to connect and charge multiple batteries at once. This allows the user to charge up to 10 batteries simultaneously, depending on which model they get. Multi-battery charger areas in commercial and industrial businesses with many applications requiring scheduled charging and consistent charger use. Here are some names of multi-bank chargers:

  • PRO-LOGIX 6/12V 4*5A battery
  • Dual pro sentinel 10 charger and maintainer
  • Dual Pro Real PRO 12 volt 2 Amp battery charger
  • NOCO GENPRO 10*2 12 Volt 20 Amp Genius 2 bank battery charger
  • Battery tender 12 volt 1.25 Amp battery charger.

Smart Battery Tenders: A smart battery or a smart battery pack is a rechargeable battery pack with a built-in battery management system usually designed for the use of portable computers such as laptops.

A smart charger is designed to observe your battery status and provide a charge when necessary to maintain your battery keeping it healthy and energized. This ensures your vehicle is ready to go and prevents internal damage caused by running your battery down when not in use.

Smart battery chargers powered by Optimate in the 1990s constantly monitor the battery topping it up when necessary so it is always fully charged. Smart charger technology ensures the correct level of power is sent to the battery at all times.

The smart battery charger is programmed with multiple automated steps and variations to provide the best environment for the battery to accept a full charge. the atypically smart charge can have up to 8 or 9 different steps to get the best performance from a battery Solar Battery Tender:

Solar battery tender keeps your batteries in optimum condition. Solar tenders look after your batteries when they are not being used. They prolong your battery’s lifespan and keep them safe by maintaining maximum charge avoiding overcharging or discharging.

Benefits of using Multiple Battery Tenders:

Once your batteries reach full charge it automatically switches to afloat mode to prevent overcharging and maintain optimal battery levels. This smart charging process helps prolong battery life and ensures your batteries are always ready for action.

Maintenance of extended battery life with multiple battery tenders:

  • Check the battery state charge. Most batteries have a state of charge indicator on top of the battery that will give you a spot diagnosis of the battery’s condition.
  • Ensure the battery top is clean dry and dirt-free or grime. A dirty battery can discharge across the grime on top of the battery casing.
  • Inspect the terminal screws clamps and cables for breakage damage or loose connection. These should be clean tight and free of added protection.
  • Inspect the battery case for obvious signs of physical damage or warpage. This usually indicates the battery has been overheated or has been overcharged
  • If you have a maintainable battery, it is important to check if the battery has sufficient electrolyte covering the battery plates.
  • When servicing a sealed maintenance-free battery, check the state of the charge indicator. if the state the charge indicator advises replacing the battery as the electrolyte levels may be below the plates which can lead to an internal explosion
  • For batteries used in seasonal applications and stored long-term, fully recharge the battery before storing. Check the state of charge or voltage regularly. Should the voltage drop below12.5 V recharge the battery completely before reconnecting the electrical device

Real-world Applications of extending battery life with multiple battery tenders:

Several criteria may be used to classify the countless applications of batteries reported. three major categories have been considered: portable industrial and traction/ automotive.

  • Automotive Batteries: An automotive battery is a rechargeable battery that is used to start a motor vehicle. Its main purpose is to provide an electrical current to the electric-powered starting motor which in turn starts the chemically powered internal combustion engine that propels the vehicle
  • Marine batteries: Marine batteries are designed specifically for use boats with heavier plates and robust construction designed to withstand the vibration and pounding that can occur on board any powerboat
  • RV batteries:  Recreational Vehicles ( RV) are one of the most important things you take with you on the road when you on the road when you travel.


  • By reducing the number of battery replacements required businesses save money and reduce the risk of lost productivity due to dead batteries
  • Extended battery life can reduce the human cost of constantly replacing batteries freeing up employees to focus on more important tasks
  • High specific energy
  • Long storage times and instant readiness


  • They are non-rechargeable
  • They are also less environment friendly than rechargeable batteries
  • These batteries have a low C rate



Does a battery tender extend the life of a battery?

Battery tender releases a slow trickle of energy into the battery to keep the charge up and maintain the charging capacity of the battery without to overcharging it

How do I choose a battery tender?

As a rule of thumb, your battery charger should be 10% to 20% of the Ah rating of the battery.
