Can I leave AGM battery on trickle charge?

Yes, you can leave an AGM battery on trickle charge. An AGM (Absorbed Glass Mat) battery is a lead-acid battery with a special design that uses special mats between the electrolyte and battery plate.

This design allows for greater efficiency in the charging process, meaning you can leave it on trickle charge for extended periods of time without any damage to the battery’s components.

Trickle charging is done by using a voltage regulator to keep the voltage level constant, usually at an average of between 13. 5 volts to 14. 4 volts. The advantage to trickle charge your AGM battery over other traditional charging methods is that it takes much longer to recharge the battery, but it is a more complete charge.

A typical charge cycle with a traditional charger may take around 8 hours, while a trickle charge may take up to 24 hours. This can help prevent battery damage, as overcharging of a battery can lead to reduced performance and lifespan.

Despite the benefits, it is still important to remember to monitor the charging process. Overcharging can still occur because of a faulty charger or excessive voltage level. It is advisable to disconnect the battery if it appears to be charging at an abnormal rate compared to its usual charge rate.

Additionally, AGM batteries should not be trickle charged in temperatures below freezing, so make sure to switch off the charger if you’re in a cold environment.

What damages AGM batteries?

AGM batteries can be damaged by a variety of factors. Overcharging the battery can cause permanent damage to the plates and shortening their lifespan. In addition, undercharging the battery can also damage it.

Deep cycling is another way to damage the battery, gradually breaking down the plates and shortening their life. In addition, temperature can also have a negative effect on how a battery will perform.
