What battery charger do you use?

[John_Mc]

AGM charges slower to a lower voltage than LA batteries. Charging AGM on LA settings with shorten the useful life of the AGM battery

I believe you are thinking of Gel batteries, They charge to a lower voltage and are very easily damaged by overcharging with a charger designed for flooded lead-acid (FLA) batteries.

There are some chargers designed for flooded lead-acid batteries that will charge at high voltages (as high as 15-17 volts). I avoid these as they are not good for regular FLA batteries or for AGM batteries.

Some AGM batteries charge using the same bulk charging and float voltages as flooded lead-acid batteries, others recommend charging at slightly higher voltages than FLA.

For the AGM brands which recommend the slightly higher voltage, using a charger designed for flooded lead-acid batteries will simply under-charge them slightly. (That’s not the greatest thing for them, but far better than leaving them more heavily discharged.)

I have an AGM battery in my Hustler Raptor X lawn mower that needs charging. I've been told that a normal battery charger (Schumacher SC-600A) can't be used. What battery charger are you using for AGM batteries? Also, the battery in my Kioti DK4510 is getting weak, and I'm thinking of replacing it with an AGM battery. Any suggestions and/or issues

NOCO GENIUS2X2 6V 12V 2-Bank 4A Battery Charger For Cars, Trucks, SUVs, RVs and Lawn Tractors – Automatic Charger, Maintainer, Trickle Charger I've been using this and like it a lot. Holds charge and maintains two 8a batteries for my john deere motor in our fire suppression room. I am sure they have single versions as well.

Anything that's competent on flooded lead acid should be fine with AGM. If you need mainly a charge maintainer, anything from CTEK is the only choice. They do everything well. CTEK has a nice plug-in assortment of accessories such as ring terminals, alligator clamps, plugs, etc. Helps if you're someone who values a near-factory appearance.

I have one AGM battery (Bosch) in a generator that's over 10yo and maintained with a CTEK 800ma charger. Still tests new. For new applications, I don't use anything other than Fullriver. Best AGM vehicular batteries made.

I purchased one from NAPA in Ontario Canada. Under $100. 2,10 and 20A. Triangular. Does the 3 types of Batteries. Trickle Chargers and Battery Maintainers are not the same animal.

AGM batteries have the same charging profile as flooded lead acid (FLA) batteries so any charger will work

Why do chargers have an agm setting?

 

[Frxdy]

Any charger that says "Smart charger".
Lithium battery note.... I never charge any lithium battery with anything except the charger it came with. Most lithium battery fires are from using the wrong charger. (or damaged batteries.)

I have a number of NOCO Genius 1 battery maintainers. Nominally only 1 amp but that is all you need to maintain a battery. Has modes for lead-acid, AGM, and lithium. One of the differences is the voltage cutoff between charging and maintaining. In lithium mode it cuts out completely because continuous low current is bad for lithium. If the battery drops to a certain threshold it resumes charge.

I have Hulkman products and like them. Good deal on their Sigma 10 charger right now. I have the Sigma 5 that does a nice job.
