Lithium Motorcycle Battery LiFePO4 YTX20L-BS 12.8V 10Ah 580-750CCA Powersports Battery For Motorcycle Compatible ATV, UTV, Jet Ski, 4 wheeler, Scooter, PWC, Seadoo, Polaris and Generator Battery

I bought this new battery in July, I wanted to return it because it quit holding a charge. I bought two. The other one is still fine instead of me being able to just have a new battery sent to me they refunded it. I gave $137. They charge me $24 restocking fee for their bad battery $6.44 promotional discount, which returned me $106 when I seen that I decided I wouldn’t buy another from them. I run a business myself, if I run it that way I wouldn’t have any customers left.

Battery is super low quality. Didn't even last 8 months. And that's with a high quality smart Lithium charger. I've only used this battery to try to hook up turn signals. I bought it because of the high CCA's. I put this in a HD ultra classic. Worked great for about 5 months. After that, stopped taking full charge. Went from a normal 13.4v full charge, to only getting as high as 12.4v..... then went down from there. If there's sibe sort of warranty, I'd take the refund and replace this with a better quality battery.

I have a 2012 Dyna 103 with Andrews 54H cams and needed more crank power in cold 40f or below weather to turn over. Installed new HD battery in spring and now needed to jump in 50f or lower morning weather. ACR's good and wanted to try lith. Batt. After 5 minutes of charging stright out of box with lithium charger it indicated full and had a resting voltage of 13.66v on Fluke meter. installed it this morning at 50f and cranked faster rhen HD batt did when new ever even when hot. Battery arrived yesterday and put on my multi mode charcer in li mode and showed full charce in 5 minutes and resting voltage of 13.6v, after fully charging old AGM batt it restef at 12.5. As of most of my 16 bikes other I have. After the fastest cranking speed it has ever had even when warm and instant start, the he charging voltage was at 14.51v at idle at 1000rpm and at 14.83v 3000rpm. After a +50 mile ride and several starts all good first day. Day 2- Checked resting voltage with Fluke meter 13.62v. Cranked and started instantly, also didn't have to reset gear position/RPM display as I almost always had to do before. The only issue I had is was I needed to shim between the top of battery and the battery box to keep the battery display button from inadvertently being pressed.

Great battery would by again

I purchased originally for my personal watercraft but winded up using it in my honda civic when the lead acid battery went bad. It works great in my car snd actually has almost double the cca for about the same price.

I bought the battery in November worked fine plenty of starting power, then in January, the battery was dead would not take a charge. Seller has not gotten back to me on reimbursement or issuing a new battery as this one is defective. Amazon is refusing to do the same after three days of continuous contact, they refused to do anything.

arrived quickly -installed and worked perfectly

You'll notice the difference in the extra 100 cold cranking amps... it's a perfect fit that replaces the stock one on my 2022 Harley Tri Glide which has a rather high compression ratio. I got tired of hearing the stock battery lug when it tried to crank it over this one gives it better power. It was a perfect fit in every way note the positive and negative are reversed on the Harleys as is this one the height width and depth were perfect as if it was made for it
