TPE Lithium Motorcycle Powersport Battery YTX20L-BS 12.8V 9AH 620CCA with BMS - Engine Start Battery with 2500-8000 Life Cycles - Ideal for Starting Batteries

This battery is awesome it starts my harley with ease seemed to stay charged for a long time after sitting the only thing I would change would be terminal screw location needs to be a little further towards the front was a little difficult to put positive termanel on but after relocating it hooked up fine came 13.2 votes out of the box and is ultra light weight I was very satisfied with overall fitment and its cranking ability gave it a A+.

I’ve bought 3 of these the last couple of years for my Micro sprint race carsThey have performed flawlesslyA bit of advise, make sure your charger has an AGM setting, traditional charging systems will cause the battery to swell and quit working….. ask me how I know!All in all a great little battery

I purchases in November of 23, it made it through the winter on my ATV, it was pretty much full voltage all winter, about a week ago I unhooked it because for some reason I could not get my starter to work and I thought it was a bad solenoid, the battery has been unhooked from everything for a week and now it is absolutely dead and will not take a charge at all. Very disappointed, I think any manufacturer that won't put a warranty behind your battery and you have to pay for an additional warranty should be looked at with scrutiny. If you're not willing to stand behind your products maybe they're not worth the purchase price. $200 for a battery that I get to throw away after it's hardly been used is not my idea of a value. I gave it two stars because it did hold full voltage for just over 6 months but then simply died and went completely dead. I did note that the negative post seems to be loose on the external but internally seems to be solid so I'm not sure if that was the factor or there's actually something shorting out inside. Will look at a different brand to replace, have never seen an AGM battery fail like this.PURCHASED 2ND OF SAME TYPE, FAILED JUST AFTER 30 DAY RETURN LIMIT. NO ONE SHOULD BE SELLING THIS CRAP! WOULD GIVE IT A ZERO IF POSSIBLE!

I've been changing batteries in autos, trucks and motorcycles since I was 10 years old. Honestly, this feels like an empty display for a battery. After having a lithium powered drill for a few years, I replaced eight lead acid batteries in my golf cart with two lithium units. When my 600RR needed a new battery, I decided to try a lithium in it. Weight wise, it couldn't possibly do the job. But man, does it ever spin the motor over. No issues with charging, or cranking, even after sitting for weeks. Dropped right in with the included spacer. Absolute great bang for the buck.

I was willing to pay the high price of the battery to upgrade my can am. On attempting to install, I realized the factory bracket and + cable setup did not work without modification. After reading the manual I decided this did not seem like the right application for this battery. First flag was the mention of avoiding shock - not good for an off road toy. Second was the switch and display on the top - simply didn't appear waterproof. My conclusion was the battery management is the weak part of the battery. Sure would like to see them make this more robust and change the top shape to match a 30L class battery.

Battery is quite a bit lighter than the lead-acid unit that was in there before, and it seems to deal better with surge currents and/or situations (such as being at idle), where the lead-acid battery I had in the bike had voltage rails that'd sag just a bit. This battery doesn't seem to have that extra output impedance, and as a consequence, the ignition system (and I have an aftermarket electronic ignition where breaker points used to be) seems not to stumble. The result is that I have the idle set quite low and the bike runs just fine. With the old lead-acid battery, I frequently found myself revving the bike at a stop because I'd get the occasional low-voltage warning.So far a stock alternator on a relatively old (1972) Norton Commando seems to charge it properly. I should note that I can't speak to cranking current, since the bike itself doesn't have a starter motor and has to be kicked. But it tends to roll over on the first or second kick consistently, which the old lead-acid unit never allowed it to do.In future, this will probably be my battery of choice.UPDATE, 12/20/2021:I'm concluding that the regulator in my bike is probably putting out a little more voltage than this battery wants to see. It's still healthy, but to be on the safe side, as I swap in a higher-output alternator, I'm changing the regulator to something I know is going to top out at no more than 14.5V. Older bipolar transistor regulators can hit 15V or more, and although this battery's protection circuits would probably kick in, that's not the ideal solution.

i LIKED THE SIZE OF THIS BATERY IT WORKED GREAT FOR STSRTING MY 21 HP MOWER/ The only problem I had was finding some small blocks to keeo it in my battery box on my mower

Battery had plenty of cranking power but only lasted 22 miles then went dead and now won’t take a charge
