72v Lithium-Ion Battery – The Ultimate FAQ Guide

The following FAQ Guide consists of all the important queries about a 72v Lithium ion Battery Pack.

To get answers to your questions, Have a look!

1. What does wh on a 72v lithium-ion battery means?

Wh stands for watt per hour and is a unit of energy or power that is equal to one watt in one hour of time.

This term is commonly used in electrical appliances.

The wh on a 72v lithium battery means the energy that can be stored on the battery.

The power is subjected in watt-hours and is the voltage that the battery provides which is multiplied by the amount of current a battery provides in that amount of time which is usually measured in hours only.

2. What kind of charger is used for a 72v lithium battery?

A 72 v lithium ion battery has a built-in protection system to absorb any shocks or extra current or voltage that may be delivered.

Lithium batteries require a charger that delivers constant current or constant voltage.

Some 72 v lithium batteries may require special 84V lithium battery chargers only for effective working and long term life.

The charger that comes with the 72v lithium ion battery is recommended to be used for effective working.

However, constant use of inappropriate chargers can ruin the battery’s working and effectiveness completely.

A damaged or leaked lithium ion battery pack can be extremely dangerous to be touched.

The acids of the battery can burn your skin and cause several problems if they come in direct contact with your skin.

You should not try to operate the damaged lithium battery pack as it may explode and cause severe damage.

The damaged and leaked lithium battery packs should be kept away from appliances and households and should be handed over to the recycling stations or e-disposing centers immediately.

27. How long will a 72v lithium-ion battery last if not used?

If a 72v lithium ion battery is stored or keep unused it will last for 2 to 3 years, the timeline provided by the manufacturers.

However, if a lithium ion battery is in use or not its charge capacity falls with time, and the battery self discharges.

If the battery is discharged to a level that it is drained, you should consider it dead.

The stored or unused battery should be monitored regularly for its charge level and charged when necessary to prevent it from draining completely.

28. How can you check your battery voltage?

You can easily check the voltage or battery status of your lithium ion battery using a multimeter or voltmeter.

It consists of a monitoring screen and depicts the voltage status of the battery it is connected to, on the screen.

Simply connect the terminals of the voltmeter with the battery terminals, and it will show the respective voltage of the battery.

This is the most effective and quickest method to know your battery’s accurate voltage

29. Does a 72v lithium-ion battery die if not used?

The battery discharges on itself and loses its charge capacity over time whether it is used or not.

The life expectancy of an unused 72v lithium battery ranges from two to three years when not in use or are stored.

The charge status of an unused battery should be monitored so it does not go bad before time.

30. At how much battery percentage should you store your 72v lithium battery?

The lithium ion batteries are considered to be stored while they hold 30% to 50% battery capacity because the battery has its self-discharge component which causes it to use the battery over time slowly even while stored.

A 72v lithium-ion battery should be charged at least 30% before storing it for a good storage period.

31. How can you fix your 72v lithium-ion battery if it won’t charge?

If your 72v lithium ion battery does not hold a charge and discharges extremely fast, you should discharge your battery completely and then recharge it to its full capacity.

If it still does not hold a charge it means the cells are dead and refuse to hold a charge.

The only solution to this condition is to replace your 72v lithium ion battery with a new one.

32. How can you dispose of your 72v lithium battery?

Lithium ion batteries should not be disposed of directly as they contain hazardous material.

These batteries can be recycled but only at specific places.

The damaged or dead battery should be dropped at recyclable places or e-waste collection centers so that safety is assured as well.
