It all depends on the battery. A standard or OEM battery is liquid lead acid battery. This type needs to be vented, mounted upright and requires water to be added periodically. They only last reliably 3 years. 4 if you're lucky and haven't pissed off the motorcycle gods. An AGM (Amalgamative Glass Mat) is a gel battery than does not need venting and can be mounted in any position. Water never has to be added. In fact, you connect it and virtually forget it. This type of battery holds a full charge just prior to discharge. You will get maximum amperage/voltage right up till full discharge. They last 7-10 years. Cost is about 50% higher than standard lead acid type. An AGM is the only type I use. A third type is a Lithium based battery that has other advantages but the cost in my opinion is not worth it - especially compared with the advantage of using an AGM battery.How long have the batteries been lasting? I'm about to replace my first one, not sure what to do.
I installed a new Yuasa YTZ14S battery in my CTX1300 and it was complete garbage in 12 months. The low 210 cranking amps were pathetic as well. Since the battery compartment measurements seemed capable of fitting a YTX20 without the L shaped spacer I considered that route, but the price was higher and it weighs a porky 13.5 pounds for only 270 Cranking Amps!How long have the batteries been lasting? I'm about to replace my first one, not sure what to do.
I researched all the options, I was looking for the highest cranking amps possible. I looked by case size to see what would fit the bike. Lithium batteries do not have the same reserve capacity of a lead acid / AGM battery, the lithiums are comparatively much lower.@HondaDreamer
I am curious how you landed on a
Antigravity Lithium battery ATX12-HD-RS
when the battery selector for a 2014 Honda CTX 1300 provided by Antigravity points a person to:

I realize there are many options, I did a lot of research and wanted to share my experience. To each his own, but sometimes it doesn’t cost any more money to go first class. After a $120 Yuasa YTZ14S that was junk in less than a year, I looked for something else. I agree a typical Yuasa can last 4-5 years or more but you missed my main point in this. I was after cranking amps.I can buy two AGM batteries for a little over $200.00 so that is why I stay with them. My original battery lasted six years. I too have heated grips but no additional lighting. No problems. The secret is buying a quality battery and they should last a long tIke.
No problem, I was just stating my experience. My CTX always fires right up. I don’t know why you feel the need for a battery with 480 cranking amps. if Honda thought you needed that much power they would have supplied one me thinks. My CTX stays on a battery maintainer battery charger while I’m not riding it as well as my other bike and riding lawn tractor and the batteries last many years. I don’t know how much current your additional lights pull, so a little extra cranking power might help, but I’m assuming they are LED lamps that do not pull the current a halogen bulb would pull. Also the weight of the battery is used to balance the bike where it is positioned In the fairing. Saving weight there might effect ride and handling. I don’t know. Just thinking out loud.I realize there are many options, I did a lot of research and wanted to share my experience. To each his own, but sometimes it doesn’t cost any more money to go first class.

•There is no AGM battery that fits the battery box that has 480 CRANKING AMPS
•The Antigravity lithium weighs 3.5 pounds.
•There is no AGM with a “Restart” feature that protects itself from discharging below the point that it won’t start the bike.
The Antigravity was my choice, you don’t have to agree, I’m fine with that, I just wanted to share what I found that worked for me.
I cannot help but wonder about the point of diminishing return on going for more cranking amps on this bike. The starter will, after all, ONLY use as many amps as it is designed for and no more. So if the max amps the starter circuit can possibly use is, say, 250 or 275 amps then 480 ca will not be fully utilized. I'm not saying that the starter is only rated for those amps. I really haven't looked into it. But I'd be surprised if the starter circuit on this bike will make better use of much more than 275 cranking amps. And I will admit to putting in a battery rated for 275 ca to replace the stock battery. But I'm with Gary in that my CTX1300 would start right up, even in sub-zero F temps. Usually it would turn over 4 times and no more... ever. But that's the nature of a fuel injected engine. It will turn over a few more times than an engine with a carburetor. My ST1100 had a carburetor and could start on 1-2 turns, but not during those sub-zero F temps. Then it was at least 4 turns. If your bike is very slow to start there is something else going on.
And, yes, the location of the battery per the Honda technology information that was published when the bike was first out. It stated that since the stock ST1300 engine was shifted to the right a little to enable the drive shaft to clear the wider rear tire (to avoid very costly redesign of the transmission) the battery was placed high and to the left to restore weight balance. Though I doubt a very slightly lighter or heavier battery there would make much of an impact. It would have to be a rather significant weight difference to be noticed.
I’m sorry if I somehow offended the CTX experts by choosing a battery that is not the one Honda specified.. I came here hoping to learn and share.
