I just spent $210 AGM battery for my Ford focus. It lasted almost 5 years. I has a 10 year old Dodge with the original acid battery in it before this car. So I guess AGM costs twice as much and lasts half as long. It's kinda like the florescent spiral light bulbs that were supposed to last 20 years that needed replacing every 6 months.

Jeff is there any plans on doing some installation video’s? I really enjoy the content on your channel.

Does AGM batteries require a special charge regulator unlike a lead acid battery that doesn’t, similar to that of a lithium battery?

[milkoberben]

If you want to have a great number of recharge cycles then I would suggest to read the battery manual and see how your recharge cycles deminish when going lower then 50 percent

Great video again Jeff, love the single question answer format it's brilliant many thanks Roy.

What agm battery brand do you recommend for use in golf carts? What about Optima as a choice and if so, which one?

[shoveljunk-americanpatriot]

My problem is the weight. I don’t have space for inspection or room to add fluid and they are to heavy to move once per month. I had to go with 2 100AH AGM. That equates to 100AH of usable charge. The necessities of being a CPAP user.

Thank You Jeff for all your informative and well narrated videos. Question, How do you monitor your AGM batteries to know at what %age they are? Thanks in Advance.

Do you have a video taking about upgrading from flooded to AGM and the pitfalls associated with it ? Thanks

With AGM batteries is there between a battery that is used as a starting battery as apposed to an AGM that is used for the hotel load? Your videos are a great resource. Thanks to everyone at PYS for their effort.

Hi Jeff, nicely shared!
I remember you said that we can parallel two or more identical battery charger in order to increase and maximize the charge of the battery bank. I haven’t found detailed infos about how to wire such two battery charger in parallel. Can you tell? Many thanks.

Hi Jeff. Great video. What's the difference between a gel cell battery and an AGM? Which has the most life cycles and what's the depth of discharge differences between the two? And is charging the batteries the same process? Thanks!

Great video. By the way does high temperature above 100 F 0r below zero F causes any damage to AGM battery? And if so what is the best way to protect them in a Travel Trailer?

Hi Jeff, loving the new series! I was wondering what the best way to join 2 cables in to 1 in the most safe and waterproof way. Something like where you would have 2 nav lights in parallel of a single feed from the helm. Thank you

Hi Jeff William here. I love your content. I have a 36 volt golf cart. With 6, 6 volt lead acid batteries. 1 battery is brand new 3 weeks old. Just pulled all of my batteries out of the golf cart to clean the acid off of the battery tray. So that it will mot corrode. When doing so I noticed that the the 5 older batteries from 2013 are no longer square. They are swollen on the sides. They still function for now. Thinking about just changing them out proactively to AGM. So I would just replace the 6 batteries with 3, 12 volt AGM batteries. Is that correct? Also would I still charge the batteries with my 36 volt charger that comes with the golf cart?

I have 2 agm batteries from autozone in my camper that are 7 years old and still show no signs of weakening

Good Morning Jeff, If you could point me in the correct direction on my question I would appreciate it, I have twin engines with high amp alternators (150 ea) 1 house battery bank (4 agms) 1 engine battery (31). Should I used a battery combiner to connect both alternators to both battery banks, or use a battery isolator for both banks and connect the alternators to it, or connect 1 alternator to the house bank and the other to the engine bank.
Thanks Jeff
Allen

Question: How do I size breakers and fuses for a given load?

[stormer]

Hi Jeff, could you perhaps do an instructional on crimping battery lugs and torquing of terminal bolts and whether to coat them with anything etc or not.. or one on setting up solar controllers charge parameter voltages.. Regards Stormer
