Description

LiFeP04 batteries are maintenance-free batteries, If you need them all the time, Then lead-acid becomes too unreliable and laborious, The battery's lithium-ion properties reduce the weight of traditional lead-acid batteries to less than half, While significantly improving performance and capacity, Traditional lead-acid batteries contain large amounts of lead, After disposal if not properly disposed of, Will pollute the environment, While lithium materials without any toxic or hazardous substances, Recognized by the world as a green battery, Its great durability allows you to easily use them at home and at work, Or safe outdoor needs , The environment is most important. Recommend using a professional LiFePO4 charger to charge the battery so that it can be charged to its full capacity (existing lead-acid battery chargers (wet, AGM or gel) will also work fine) Lithium ion batteries can be discharged up to 100% without causing damage. Make sure to charge the battery immediately after discharge. We recommend limiting the discharge to 80-90% depth of discharge (DOD) to avoid disconnection of the battery by the BMS. 12V LiFePO4 battery have no liquid inside.

    • Great upgrade over SLA batteries
Size: 12V 7Ah
I purchased this battery to replace the worn-out SLA battery in the small UPS (uninterruptable power supply) I use to back up my desktop PC. The decision to switch from SLA to Lithium-iron-phosphate battery chemistry was easy as LiFePO4 batteries cost about the same as SLA batteries but are much lighter and last much longer than SLA batteries. My UPS is over ten years old and, at the time I purchased it, SLA batteries were considered the battery of choice. If purchased today, it’s highly likely the battery would be LiFePO4 technology. LiFePO4 batteries are easily confused with Li-ion batteries commonly used with portable power tools. LiFePO4 batteries are more reliable, have longer lifespans, and are safer than Li-ion batteries. The battery easily fits into the same space as the SLA battery it replaced. I haven’t needed to find out if the battery works as well in a power out scenario, however, my UPS runs a test program several times a week so I’m certain I can rely on it should the need arise. ... show more

    • Great replacement for lead-acid battery in an automatic deer feeder
Size: 12V 7Ah
I purchased this battery to replace a 12v sealed lead-acid (traditional) battery in an automated deer feeder. This particular feeder throws three times per day on a timer, for a total of about 35 seconds dispensing feed using a spinner plate/motor. There is a solar panel to keep the battery charged on sunny days. The feeder was basically killing a battery per year using the traditional lead-acid units. This was my first experiment with lithium batteries in this application, but I have a lot of experience with them more generally. I waited four months to write this review, and so far I cannot lodge any complaints with this unit. The battery has performed perfectly. If anything, the feeder now throws much more strongly than it ever did with the lead-acid battery -- we have nicknamed it the "corn cannon" with its new power source. The battery has been zero-maintenance since it was installed, and I haven't touched it in four months. All status indicators are fine. NOTE: My only concern will be winter time, as it is very bad for lithium-based batteries to charge at below-freezing temperatures. Luckily this is a very unusual situation where I live -- only the few coldest days of winter are freezing during any daylight hours, and it's often overcast when it's that cold. If we have any "arctic fronts," I'll probably just disconnect the solar panel to keep the battery from charging during a weather snap. Discharging lithium-based batteries below freezing is not nearly as bad for them as charging them when it's that cold out. Those in colder climates might consider this issue if you plan to deploy this battery in an outdoor environment. ... show more

    • DO NOT BUY, CHEAP CHEAP CHEAP
Size: 12V 7Ah
Battery initially worked great. Recharged with no issues. 3 months later and battery is dead and won’t recharge. Had local battery shop check battery and they said it’s bad. Definitely won’t buy again. Guess that’s what I get for buying a battery from Amazon.

    • Saved my string trimmer.
Size: 12V 7Ah
I was ready to throw away my battery string trimmer cause the lead acid batteries died after a year and never would trim my whole yard without a recharge. I decided to try this battery as a last resort to buying a gas powered one. I just trimmed the whole yard (about half hour) and when I put it on the charger it indicates an almost full charge left. Not sure if I needed the special charger but I got one anyway. ... show more

    • After 3 uses it stopped working on my Garmin Fish Finder
Size: 12V 7Ah
After using it 3 times, it just doesn't power on my fish finder anymore. It's fully charged. My fish finder will power on if I connect the charger to the battery terminals; it's as if it needs a jump start. But this isn't feasible when I'm on a kayak. I've checked the connections, and it's fine. Update: About a week afterwards, the company reached out and refunded my money. The Customer Service at this company is good. So, I'm revising my 1 star review to 4, cause they made it right. ... show more
