Using a conventional battery charger on an AGM battery could cause severe damage to the electrolytes and premature failure to the battery. Conventional chargers also have the potential to cause an AGM battery to literally explode – a hazard that we never (ever) want to expose to our technicians.

What causes AGM batteries to explode?
During the final stages of charging, all lead-acid batteries break down some of the electrolyte in a battery into hydrogen and oxygen.However, if a pocket of gas forms, any spark (such as from a brushed electric motor kicking on) may set off the hydrogen, on occasion resulting in a powerful explosion.
Are AGM batteries safe?
▶ AGM batteries can be stored safely for up to a year before requiring inventory maintenance.Take precautions to ensure batteries are fully charged prior to storage, are kept clean and dry – and are protected from impact and free of any connections that may cause parasitic loads.
Do AGM batteries need venting?
Even though AGM batteries are considered to be maintenance-free, they still require venting. If you overcharge the battery or charge it too quickly for the absorption mat to keep up with, the same dangerous build-up of hydrogen gas can occur.
Can AGM batteries spill?
The glass mat technology in the AGM battery makes it spill-proof and position insensitive.However, the flooded cell battery has a liquid electrolyte, so it must always be upright to prevent spills.
What happens if you overheat an AGM battery?
If your AGM battery feels warm towards the end of its charging cycle, don’t worry. It’s normal for AGM batteries to warm up while charging, and you can still use it to charge your other electrical devices.It’s overheating while charging (and possibly being overused), so it needs a break.
Are AGM batteries flammable?
Unusual fire and explosion hazards: If AGM batteries are properly charged they will not release any flammable hydrogen gas. If they are excessively overcharged the safety relief valve can open and release flammable hydrogen gas.
What happens if you overcharge an AGM battery?
Overcharging an AGM battery can lead to reduced battery life. Many modern chargers allow you to select whether you’re charging an AGM battery or a flooded cell option.
Can you Desulfate an AGM battery?
Keeping your AGM battery charged during and before storage will help to avoid the process of sulfation. In case sulfation occurs on your AGM battery, use a desulfation charge to reverse the sulfation. You can also use the AGM battery recommended charger to lower the impact of sulfation.
What happens if you charge an AGM battery with normal charger?
You can use your regular battery charger on AGM or gel cell batteries. False. These batteries like to be charged slow and low. Many AGM/gel cell battery chargers have microprocessors that collect information from the battery and adjust the current and voltage accordingly.
Do AGM batteries need to be upright?
Because the liquid electrolyte flows freely inside conventional batteries, they must be mounted and stored upright to prevent leakage. AGM batteries, on the other hand, can be mounted in any orientation because the liquid is sealed inside the battery.
How many years do AGM batteries last?
A properly maintained AGM battery usually lasts somewhere between three and four years, but this depends on the amount that you use it. Also, the amount that you drive your vehicle plays a role in how long the battery will last.
What happens if you don’t vent a battery?
If the battery is not vented, then it can cause fire or an explosion in your vehicle. Sometimes these gases could leak from the battery and can make you sick. Although these gases don’t kill you, they can harm your health. This is not worth it, so you should ensure to vent the gases from your battery.
Can you mix flooded and AGM batteries?
You CANNOT mix and match AGM and flooded battery types on the same battery charger. You’ll need a different charger for each different type of battery or it will shorten your battery life.
What is the main disadvantage of an AGM battery?
The main disadvantage of an AGM battery is the up-front cost, when compared to a traditional flooded lead-acid battery. That’s it.
How do I know if my battery is AGM or flooded?
Basically, an AGM battery will always have a flat top, and only the negative and positive terminals of the battery will be sticking out. On the other hand, the liquid acid batteries have a removable top which is not the case with AGM batteries as they are properly sealed.
How hot can a AGM battery get?
TPPL AGM batteries, such as ODYSSEY® Extreme Series™ batteries, are designed specifically for high temperatures. They can reach up to 176°F (80°C) and not lose internal water, as the battery remains sealed during its operation.
How hot is too hot for a battery?
It really depends on the cell chemistry, but as a general rule of thumb you don’t want to go above 35°C (95°F), and you should expect permanent damage to some extent at 50°C (122°F) and above.
How hot is too hot for batteries?
How hot is too hot for the lithium-ion battery? After 45 degrees Celsius, the warm weather will be not favorable for lithium-ion batteries. It maybe takes to 50 degrees but in many cases, 45 is the maximum point.
Are AGM batteries safe to use indoors?
A.G.M. batteries do not give off any gas (hydrogen) when being charged, so there is less concern about ventilation when charging them. This allows them to be used safely inside a motorhome. 4.
Can deep cycle batteries catch fire?
In addition, deep cycle batteries can release hydrogen when they experience overcharging. This is due to electrolysis of the water in the electrolyte. Normally the gas dissipates quickly. However, this gas can ignite by a nearby spark (for example, when removing the jumper cables).
