With batteries I just have a hard time justifying the cost of amps and amp hours.I am stuck with 6-8D AGM with out redoing the battery compartment. I could have gotten the same amp hours for  $.50 to $.75 per amp  instead of $3.00 per amp it came out to be under $800.00 for golf cart batteries vs $4900.00 for the AGM that is a huge difference for batteries that have about the same life span  ??? just food for thought 30 minutes every 3 months to service wet cells I could have done that for the $4100.00 difference in price   


I could make a heck of a lot of renovations to the battery compartment for $4000 savings!

Just bear in mind that you cannot check the Specific Gravity of any type of sealed battery such as AGM or gelcell.   With good ol' flooded lead-acid batteries you can easily check their SG every month, and top up with more water if needed  -  this can greatly prolong their life.

If your space constraints require AGMs they're your only option, but if you have space to access FLA batteries they will be the lowest cost per watt per year.

Jon expressed my sentiments exactly. He could also have thrown in depreciation, or devaluation if you want to call it that.   That's why I'm getting out of this silly game, too spendy for me after 25 years working on buses.  I do like them though but as they say, a want is not a need.  BTDT.

Yes AGM batteries are 2-3 times more expensive then wet batteries. And yes it is easy to check the water in the wet batteries 4 times a year-less if you use Thermoil. But AGM batteries have much more than that to offer. Since they are sealed, (as long as you don't over charge them) they don't out gas-which means your terminals will never get dirty-I didn't clean mine in the 7 years. Because they don't outgas, you can mount them inside. You can also mount them in any position-up, laying on their side-just not upside down. And because the internal workings of the AGM allow for charging twice as fast as wet batteries. Personally-they are worth the extra money. Good Luck, TomC

TomC I am not trying to give you a hard time but LifeLine has changed the way to install their batteries they now want a space around each battery and install in a well vented area and it says on my instruction sheet do not install in a confined area like living quarters you can read it on their web site,they changed the whole ball game at the end of 2015
