Fire Power HJTZ7S-FP Featherweight Lithium Battery

I switched from a lead acid battery on my 2013 Yamaha FZ1 to a full-size lithium battery 5 years ago. The difference in weight was astounding.I moved across the country and did not ride for 3 years so the lithium battery died and I could not recharge it. I went online to find another battery and saw this one at a super low price, it had good ratings so I went for it. When it arrived I thought it was a joke,​ the battery is so tiny and light I thought there's no way this could work!I installed it and the bike fired up instantly, with amazing cranking amps. I keep it plugged into a battery tender now I was just off it for a month and got back on,​ it fired right up with no problem. You won't believe how small, light, and how strong it is.​Don't hesitate, buy this one now​

Fit my 2016 Yz450fx fine With use of foam provided. Super light!!! Much cheaper than other battery brand options. It’ll do the job for a few years I’m sure.Update: As of 5-25-18 battery still functions as it did new.Update: 5/04/19 still cranking strong11/15/19- over two years now! Not one problem. Still strong crank. I have never used a tender on it. Sometimes sits for weeks at a time. I was here looking at this again to possibly buy another as a preventative measure. My bike has no kick starter. So I don’t want to be stranded. But it’s hard to spend money on something that is not broke.10-29-20- 3 Years!!! And still going strong. I even crashed and didn’t ride for 2 months. Fired right up after getting back on the bike. Once again, I’ve never used a charger for this. I am hoping to buy a 2021 Yz450fx in a few months. So this battery will never get replaced. If not I’ll update if it dies.Nov 2020, sold the 2016 fx with battery still working great.Nov. 2022, I’m here buying a battery for my 2021 yz450f, figured I’d make a note.

The media could not be loaded. Great battery! Expensive. But compared to other lithium battery it is a bargain. I put this super small and lite battery under my cafe seat. I even used it in my enviro management class to show just how far technology has come. It is working great on my CX500. Cranks right up. Is recharging with the 1981 technology on my bike. I did not make any mods to my honda cx500 charging system. I have put 91 miles on it plus lots idle time. I discharged it while troubleshooting and installing my lights, then tried to charge it with my very old deep cycle charger. It would only half charge and I was worried it would damage the battery. So I went and bought the "battery tender plus" for lithium batteries from walmart. Wow! It fully charged in like 8 minutes! See my pix and listen to it crank. I would but again.

This went into a Honda Big Ruckus. So far it seems excellent for that application. I will know more about longevity as time passesKen Carman

Bought this for my 2016 Ninja 300 to replace the stock 135cca acid battery, as I was sick of tinkering with it, replacing it, etc.The included foam pads were 100% required, as the battery is so much smaller (and lighter) than the OEM size. The battery level indicator (located on top of the battery) showed the battery as fully charged on arrival, and upon testing with a multimeter, I could confirm that it was at about 90% charge and within required voltages.Battery installed simply enough, though the included screws had smaller heads than I would've liked, they still worked fine. Bike started up instantly with 0 issues, rode fine, powered my installed phone charger, as well as aftermarket HID headlights, halos, and aftermarket horn with no sign of power drop.

14 month update (original review below)My warranty expired in September. The battery died in November. Even though lithium batteries hold their charge for far longer than a year, I still use my battery chargers (specific for Lithium batteries) to maintain them, rotating them from one bike to another each month that they've not been run. It was this battery's turn. Connected the charger, got error message. Checked for voltage across terminals: zero volts. I probably won't be purchasing this brand any more.--------------------------------I've been replacing the lead acid (conventional and AGM) in my motorcycles with Lithium batteries gradually, over the past 3 years. I started with Shorai with the first one and was happy with it, but they got much more expensive. Then, the next 2 bikes got Battery Tender LiFePo batteries, but they then became much more expensive. So, I went with FirePower after seeing the competitive price and good reviews. So far, so good. So far, so good. I still like the Battery Tender brand, these come with enough foam blocks to fit any air box and terminals on both sides of the battery, but not worth the $30 additional that they cost. We'll see in the long run....

These batteries are Great , very very light ,very well made ( sealed ) and very high. poweroutput and very little power loss during periodsof storage. I have two small 250cc motorcycleson my ranch and after I bought this battery forone of the bikes as a ‘test’ , I went ahead a boughtanother for the other bike just to get rid of its old heavy , wet lead acid battery . So far , I am very happy with the two batteries I have. They evenhave a small LED strip of 4 small blue lights andyou can press the small button on the strip and it will tell you what charge state the battery has .( 25% 50% 75% & 100% )
