For all methods of transport the U.S. legal requirements are laid down in the Code of Federal Regulations (CFR 173.159) which state: 1. Batteries should be individually wrappedso that there is no chance of the terminals coming into contact with any external material or other battery terminals in the same package –. . Non-spillable lead acid batteries (those that use Gel or Absorbent Glass Matt technology) require the same packaging as those filled with acid with the following differences: 1. No acid proof liner is required. 2. The box must. . Carriers will usually require these to be drained of acid and enclosed in an acid proof liner. Some may state that the battery is also covered. . Just because your lead acid battery won’t do what you want it to do like start and engine does not mean that it is completely dead. Shorting out the terminals could still cause over-heating, an explosion or a fire. As such, so long as the. The package should be labelled with the Hazardous Materials 8 label that also include the UN number and proper description “Batteries, Wet, Filled with acid”. [pdf]
Required on all batteries defined by the International Air Transport Association (IATA) as spill-able. See Shipping lead acid batteries. Minimum size: varies, measure the total package size and check with your carrier. Required when shipping non-spillable lead acid batteries by air and also required by some carriers.
First things first, unless there is an exception of some sort, a class 8 corrosive label and a class 8 placard would be required when shipping lead acid batteries. But when it comes to packaging, there is a bit more that needs to be discussed. Let’s take a look at the various domestic and international regulations.
Let’s take a look at the various domestic and international regulations. For the purpose of this blog, we will be examining Lead Acid Batteries classified as UN2794 which are Batteries, wet, filled with acid. Per the 49CFR 173.159, lead acid batteries must be packaged in a manner to prevent a dangerous evolution of heat and short circuits.
Per the 49CFR 173.159, lead acid batteries must be packaged in a manner to prevent a dangerous evolution of heat and short circuits. This would include, when practicable, packaging the battery in fully enclosed packaging made of non-conductive material, and ensuring terminals aren’t exposed.
See Shipping lead acid batteries. Minimum size: 100mm x 100mm. Note the purchase . Purchase link (no wording – this link is for a IATA approved label but some carriers also require the label to state the UN number and the text “Batteries, Wet, Filled with Acid” as the sample on the left shows. Check with your carrier first ).
Most Sealed Lead Acid batteries using Gel or Absorbent Glass Matt (AGM) technology is classed as non-spillable while even a ‘sealed’ standard lead acid battery with liquid electrolyte is spillable.

Myth:Lead acid batteries can have a memory effect so you should always discharge them completely before recharging. Fact:Lead acid. . Myth:Never store a battery on a concrete floor because it will suck the energy out. Fact:There was truth to that 75 years ago when batteries were built in hard-rubber cases because acid would weep through the case into the concrete. . Myth:Maintenance free batteries never require maintenance. Truth:There is no such thing as a maintenance-free battery, and IEEE recommends. [pdf]
Since that is no longer an issue (and never was an issue with lead acid batteries) there is not a need to fully discharge. By discharging a lead acid battery to below the manufacturer’s stated end of life discharge voltage you are allowing the polarity of some of the weaker cells to become reversed.
Lead acid batteries should never stay discharged for a long time, ideally not longer than a day. It's best to immediately charge a lead acid battery after a (partial) discharge to keep them from quickly deteriorating.
Myth: Lead acid batteries can have a memory effect so you should always discharge them completely before recharging. Fact: Lead acid battery design and chemistry does not support any type of memory effect.
It's best to immediately charge a lead acid battery after a (partial) discharge to keep them from quickly deteriorating. A battery that is in a discharged state for a long time (many months) will probably never recover or ever be usable again even if it was new and/or hasn't been used much.
Personally, I always make sure that anything connected to a lead acid battery is properly fused. The common rule of thumb is that a lead acid battery should not be discharged below 50% of capacity, or ideally not beyond 70% of capacity. This is because lead acid batteries age / wear out faster if you deep discharge them.
Figure 4 : Chemical Action During Discharge When a lead-acid battery is discharged, the electrolyte divides into H 2 and SO 4 combine with some of the oxygen that is formed on the positive plate to produce water (H 2 O), and thereby reduces the amount of acid in the electrolyte.
