The battery in my 2007 Sportster 883 is not holding the charge. I am thinking of replacing it either with an AGM or lithium battery. Any suggestions?

 

..agm...

 

I have a lithium one in my Glide, but that is a custom application and I wanted a high performance battery to go into a confined space. They are coming down in price and are remarkably lightweight, but for a stock application I also would chose AGM. They are also high performance, though not to the same degree as some lithium ones. I suspect you will find that a new AGM battery will have higher performance than your original stock one did, so you'll be better off anyway.

 

AGM, don't fiddle around with Lithium, the extra expense not worth the weight savings for a stock application. I just installed a Duracell AGM in my Heritage, so far, so good...

 

On my bike, the weight savings and price of lithium were well worth it. If my old heavy battery cracked the oil tank mount, big expense! Not having to use a tender or check fluid, priceless. I have not even touched it since install four years ago.

Shorai lithium for me.

I have a custom Yamaha Warrior 1700cc that i put the Shorai lithium battery in about 4 years ago. I have gone as long as 1 1/2 months without starting in the winter, and it will turn over like it's fully charged. I have never used a charger on it since new and it is holding up great. I don't think i will put one in my 2013 Road Glide because of how much they cost and i ride it most of the time so it stays charged without having to use the battery tender. I will probably go with the AGM battery if i have to replace it.

 

I have seen enough problems with lithium batteries. I don't want one going into melt down under my *** at 75 mph on the freeway

 

I have both and the lithium battery give me more problems then its worth i am sticking with a AGM from here on.

 

Yuasa AGM here

 

Your original battery just gave up the ghost? That's 11 years. Seems like that fact alone would be enough to tell where you might want to look when it comes to replacing it. The OEM HD AGM batteries are made by Deka. I would skip buying an HD replacement and save some money by buying a Deka. It's essentially the same battery but for far less. Last I checked the Deka ETX14L was going for ~$70 on Amazon. Compare that to the HD's price of $115 for essentially the same battery.
