Battery charger ?

[David H]

Hi all
Accidently charged my conventional battery with the charger set for AGM battery.
Did I damage battery too much or at all.
I googled the heck out of it and could not find an answer.
Thanks David

I doubt it.

You took a couple of years off of its life, but you won't know how many until it dies. I wouldn't worry about it. Better to charge a conventional battery in AGM mode, then charge a AGM battery in conventional mode.

Just a question what does the AGM mode do/?
More current or voltage?
Thanks David

AGM batteries shouldn't be charged as quickly as conventional LA batteries so the AGM charges the battery more slowly. so usually less amps

I seriously doubt you did any harm....
according to a Google search conv. bat is 12.70 v, agm is 12.80 v
that .1 v 'over charge' might not even have occoured.

first what 'charger' did you use ? 'smart','trickle','SCR', 'stupid' ? There's at least 11 types of 'chargers' I've designed/built/repaired over 45 years.

2nd, what DVM do you test voltage with ? EVERY DVM/DMM is +-1 digit. So if it reads '12.7' it could be 12.6 to 12.8. Nature of the beast, NO exceptions.

3rd, what battery ? capacity and age are important factors, as it room temperature where charging was done. Depending on mfr/mdl/cap/age of battery it will require different charging methods to properly recharge the battery.

This article says there is no harm done to the lead acid battery by using the AGM charger. It simply charged the battery at a low 2 volt rate. NO harm done.

Yep, no harm done at all, if anything it's a better way to charge a regular lead acid battery.

It was a harbor freight batt charger that has 2 amp 10 amp and 50 amp jump starter.
was very inexpensive but needed jump starter and old scumacher did not have that.
I do not know a great deal about the different voltages it produces.
It was about 40 deg for car and tractor batteries.
age of batt is about 3 to 4 years

Your battery will be perfectly fine. No harm done using the slower charge rate of the AGM setting. Breathe easy.
