12V 9Ah Lithium Battery, Deep Cycles Rechargeable LiFePO4 Battery with 4000+ Cycles and Smart 15A BMS for Small UPS, Alarm System, Fish Finder, Lighting, Power Wheels and Ride-on Toy etc

This battery replaced an old, failed sealed lead-acid battery in my home alarm's electronics box. The old battery lasted 5.5 years and said on its case "replace every 3 to 5 years". I expect that the new battery will last 10 years or more in standby usage, but only time will tell! The installation was easy with the included adapters that enabled the alarm wires to plug onto the battery's blade terminals. The key thing is that the battery seems to work. The previous low voltage alarm (for the dead lead-acid battery) has stopped and all seems to be working properly. I am happy with my purchase - a theoretical doubling of battery life for a 25% price premium over a lead-acid battery. Good deal.

replaced my kids toy ride with this. worked well for the first 5 chargers then 0v. life too shortUPDATE: I was reached out by the customer service and they have resolved my issue with a new battery. so far its been on week 3 and still going strong after charge. great customer service.

Upgrade your battery-surge protector-back-up units with these Lithium batteries for longer life and much lighter weight! Far more cycling times rated compared to typical sealed types. Just unplug your unit, open the panel or unscrew the cover , unplug the battery-remove old battery-drop in new replacement, re-plug the red/black clips and close cover or screw back together and you have an upgraded and improved surge/battery backup unit! More expensive than conventional batteries but well worth the improvement-Highly Recommended!

I have a Liebert UPS that uses 8 of these batteries and they are supposed to be a direct drop in for the Sealed Lead Acid (SLA )ones they replaced. I ordered this particular Lithium Iron Phosphate battery because the BMS was rated for 15 amps. During testing, it cycled twice and then they would not hold a charge. I returned all of them. I never drew more than 4.5 amps during the test and the unit works fine with SLA batteries.

Replaced bad battery in kids power wheels

I use these for all of our grandkids ride-on toys that take 12v batteries. They are a good value for the money, most are drop-in replacements meaning no wiring to perform or changing of pig-tails and they hold charges great.

I have an APC ES 550 that I use to back up my router & cable modem for home internet. It goes thru an SLA battery every 2-3 years. The LiFePO4 battery fit perfectly and was much lighter. If it approaches the expected lifetime, it will be money well spent!

Great replacement for my vexlar, Definitely recomend
