deep cycle battery agm vs standard which battery is better? 

But Gel behaves better in hot climates

How are the internals different from a car battery?

Regular flooded batteries don't freeze either at cold temperatures as long as they're fully charged.

Biased much? Flooded lead won't freeze if they have a reasonable charge, certainly enough to start the vehicle they were meant for, at that temperature. The performance is irrelevant otherwise, except for greater lifespan, and yet, the lifespan in dollars per year is "usually" lower. This leaves one decided advantage which is offroading, resistance to vibration, and orientation at odd angles. Frankly I think the time is near where vehicles will just move to a smaller battery combined with a supercap array. I see people using the supercaps but trying to pick one or the other instead of leveraging the strengths of both together.

It should be fine, just check the charge voltage from the bike at mid revs and make sure it doesn't go above whatever the battery specifies as the max bulk voltage (Typically 14.4V)

thanks! I'll have a look

You'll be OK, I had a 12v 20ah AGM battery in my Civic for 2 years. They cost 40 on eGay

never a good idea.. flooded and AGM charge differently, The charger may overcharge the AGM as a result.

I've done it and it works fine, as long as you satisfy the charge and discharge parameters of all batteries involved at all times.

look into lithium ion batteries

I thought those were small batteries only for cell phones, etc. Have any examples?

theses batteries are available in large size as well,iv seen them have 300ah ........do a you tube or google search lots of info on them ...heres a link whrer you can buy them but be prepared,they are expensive.......www.lithiumion-batteries.com/products/lithium-ion-solar-batteries/

I believe you are correct, from what I am told Gel is superior to AGM for deep discharge but very $$

+gonepriused A blue sky MPPT charge controller wont let you down www.blueskyenergyinc.com/

Interesting. Most likely it is a deep cycle battery. Try doing a google search on the part number for the cut sheet on capacity.

An AGM battery is capable of cycling, but it is not a true deep cycle battery. You will not get as many cycles vs a DC battery.

Correct, flooded typically have higher life cycles with proper maintenance

+Joe Rickard Always leave enough room for batteries to swell as they age. May be difficult to remove them after they swell and push together, especially the AGM

I 'believe' the life is similar, 'if' you keep up the electrolyte 'monthly' in the Flooded battery! Albeit, one can get different options, where flood acid 'should' get 5 years if taken care of, and AGM 'can' get 7 to 10 years of life!

Mike Brink yes desulfation techniques work. Do not recommend equalization unless you standby and monitor battery temp. stop charging if it gets hot

You said the magic word ... Lexus ... anything after that is uninformed/misunderstood due rhe nature of luxury car buyers. There is no way to put your comments into a real, scientific context. Luxury car buyers don't understand realities/ science, in general. They "buy" their way through life. ..and then brag........ which is of no use to anyone. Had you spoken differently, in real, scientific, logical terms..I would have considered them... A car is just a car...they all follow the same physical laws of science....not the emotional world of luxury people.

lindy2341 typical broke Whiner, lmao

How is the inside of a marine battery different than a car battery?

We have about 50 brand new flood lead acid batteries in stock and if we do not keep them maintained they will drop about .1 volts every about 10 days or so, therefore they will discharge at a rate of about half a percent a day if you do not keep them charged up on the other hand AGM batteries loose one to 3 percent a month. Nothing is wrong with Lead Acid batteries as long as you keep them up but AGM batteries are worth the money if one can afford it.This man is speaking the truth!

No, you didn't. Your alternator may not have been performing up to spec but was definitely putting charge into the battery for it to have lasted that long. A fresh/charged battery CAN start a vehicle 7 times no problem, but not do that and power the vehicle the whole time. Recognize that your battery or alternator light coming on just means the voltage dropped below optimum, not that it's doing nothing. This is fact. You obviously don't understand how much current is used driving. It's more than starting in total Ah by multiple times.

@@stinkycheese804 i have drivin 100 miles on a dead alternator at night with lights on, in a 84 subaru with a carb. and yes alternator was 100% dead. i broke down eventually the next day. carb cars dont need full power like EFI.

@@tonymemory2279 Apples and oranges, talking about a vehicle without electronic engine controls or fuel injectors. Even then, 100 miles would be atypical with lights on. The point is, don't plan on it because it is unusual then, and practically impossible with a remotely modern engine (remote meaning less than 25 years old).

I have seen people open the cells on AGM and add electrolytes but very certain will void any warranty

They perform better but are also susceptible to cold weather current reduction.

mick ladd Yes you can use AGM battery is perfectly fine

Deep Cycle Battery San Diego thanks

the result is never good

and why do you need to use them on their sides,please ? for your info, they ALL are the same tech,lead acid,and they last about the same, they do the same, just the agms cost much more, go figure

@@josepeixoto3384 For your information my motor bike has on on it's side as do NBN power back up supplies. AGM means absorbed glass mat.

@@josepeixoto3384 A quick google search would tell you. "The acronym stands for “absorbed glass mat” and that's one of many improvements made to Planté's original train light battery. Glass mats, cushioning the ultra-thin lead plates, will squish like a sponge. In turn, manufacturers can squeeze more glass mats and lead into one battery. More lead equals more power. AGM batteries are extremely resistant to vibration, are totally sealed, nonspillable and maintenance-free. AGM offers better cycling performance, minimal gassing and acid leakage when compared with conventional lead-acid batteries. The end result of all of the features of AGM technology is superior life performance. The leading advantages of AGM are a charge that is up to five times faster than the flooded version, and the ability to deep cycle. AGM offers a depth-of-discharge of 80 percent; the flooded, on the other hand, is specified at 50 percent DoD to attain the same cycle life."

In the past gel batteries would have higher life cycles current AGM by Leoch and other brands are producing higher Cycles now

@@DeepcyclebatterystoreSanDiego so I should go with agm then? I was told gel is better but from what I can see agm is better choice.

the vent allows the battery to gas, do not plug it please

Yes, no problem, it would be an upgrade

AGM is almost always heavier

lithium batteries

AGM, charge faster

That's great I already bought two of those in 100ah lol Thanks!!! But- I noticed that they don't take as much on the charger ... the trojan 12v 27 group 100ah takes a higher charge I think... maybe only .30 to .50 but ....

He’s a salesman, he sells them 🤔🇬🇧

good intel! Gel and AGM are cousins but not same

Bs

agree or use a heat shield/sleeve

@@DeepcyclebatterystoreSanDiego hi i have a burning question can i use a dcdc/s charger fed by alternator/solar to charge single battery setup

@@damienfrizzell9394 Yes, RedArc (AUS) has a cool item that does that

@@DeepcyclebatterystoreSanDiego cheers so i cant use my existing projecta one?

While flooded batteries do require maintenance, if taken care of properly this battery type will last longer than many of their counterparts. www.crownbattery.com/news/agm-vs-flooded-batteries-what-you-need-to-know

If you converted into a sleeping area do you have room underneath the bed? We have seen people lay the larger 12 volt AGM batteries on their side or on their ends to accommodate

A fantastic although expensive solution would be to drop in a battleborn 12-volt 100 amp hour lithium iron phosphate battery that meet your Dimensions. It will replace two 6 volt 200 amp hour batteries

@@DeepcyclebatterystoreSanDiego But can these batteries replace automotive starter batteries? do they have the Cold cranking amps and will they charge correctly from a 160a alternator designed for Led Acid batteries?

@@12vLife perhaps running two battery system. 1 battery starts the motor. The other battery is the house power. In-between the batteries use a sterling DC battery to battery charger
