    • Update - failed within 1 day
Style: 12V 18Ah
Review Image by RCAddiction RCAddiction
Update 4 days later, 10/11/2024 Well...this did not work out. The battery arrived and was installed on Monday, just before Hurricane Milton struck Wednesday night. After a1/2 second test crank (which was fine), the battery was connected to a new LiFePo4 battery charger designed for this battery chemistry. The charger itself may be suspect, as the battery would not accept a charge. The charger displayed a fault mode after a few hours. I then connected it to a known good charger. After a charge of several hours at 2amps, the charger had to be disconnected as we prepped for the storm. A quick check on Tuesday (the next day) found that the generator would not start. Did not have time to do diagnostics with the storm coming. Had to pull-start the generator after we lost power Wednesday evening. Did diagnostics today, Friday 10/11. No problem with the starter motor, as it started immediately with my portable jumper pack. The Nermark battery showed less than 10V on my DVM. Both chargers displayed a battery fault, and were unable to charge the battery above 10.3V. It's possible there was an issue with the built-in BMS (Battery Management System), but I don't know. It's getting returned once Whole Foods is open again. Original Review 10/7/2024 Very simple installation to remove the old sealed lead acid 12-18 battery and replace it with this one. I have been using LiFePo4 batteries in my RC aircraft for over 20 years and I'm glad that this battery is available to replace the typical unreliable lead acid battery that is used as a starter in portable equipment. I took the opportunity to install the terminal rings and cable for the appropriate 3 amp charger and even without completing the charge, did a quick test start on my generator. I hope it will last several years, as this generator is only used for hurricane emergencies. However, I have batteries of this chemistry that are over 20 years old and still hold 80% or more of their charge. I will report back and update this review in the event that there are any failures, or possibly great news to continue to report years from now. ... show more

    • Didn't last long...
Style: 12V 20Ah
Worked great while it lasted. Had it hooked up to a chicken coop door and 30W solar panel. After about 4 months (just outside support window) it stopped taking a charge from either the solar panel or a battery charger after I hooked it up. Eventually just degraded down to 1V. Maybe I got a dud... *** Seller contacted me and offered a full refund which is generous since product is outside return and support window. I’d already replaced the battery but I’d give it another shot especially since they backup their product. I upped to 4 stars based on product support. ... show more

    • More amp hours and lighter than traditional lead batteries
Style: 12V 10Ah-2PACK
I purchased these to replace old batteries in three of my Furman F1000-UPS systems. They came fully charged. These solid state alternative batteries have more amp hours than the original batteries (10Ah vs 6Ah) and their lifespan should be longer than the typical 2 years for UPS batteries. They're also a bit lighter than traditional lead acid batteris. So far I am very happy with them. ... show more

    • Toddler Torque on a Budget
Style: 12V 10Ah-2PACK
Ladies and gentlemen, start your engines! Or rather, start your Power Wheels—because we're diving into the electrifying world of toddler transportation with the 12V battery. Buckle up (if your Power Wheels has seatbelts), because this review is about to take you on a wild ride through battery-powered bliss. Let's start with the design: it's a chunky block of power that looks like it could jump-start a monster truck or launch a rocket (okay, maybe not that last part, but let's dream big). With wires sticking out like enthusiastic spaghetti strands, it's the epitome of childhood adventure waiting to happen. Performance-wise, this bad boy delivers. Need to outrun your neighbor's dog on four legs? Done. Want to impress your playdate with your speed demon skills? You got it. The 12V battery turns your miniature vehicle into a race car that Vin Diesel would envy (okay, maybe not Vin, but definitely someone in a go-kart). But wait, there's more! It's not just about speed; it's about endurance. This battery will keep your Power Wheels zooming around the backyard long after you've lost track of time and your parents start wondering if they should bring out the search party (hint: they won't need to). And the charging time? Prepare for the patience of a saint because waiting for this bad boy to juice up is like waiting for your avocado to ripen—agonizingly slow but oh-so-worth it when you finally get to indulge in the green goodness. In conclusion, the 12V Battery for Power Wheels isn't just a battery; it's a ticket to toddler paradise. Whether you're cruising at a blistering 5 mph or pretending you're in a high-speed chase with imaginary villains, this battery powers your imagination as much as it powers your wheels. So, grab one today, strap in (or hold on tight), and let the adventure begin! ... show more

    • Good portable LiFePo4 battery for POTA activations
Style: 12V 20Ah
Bought this LiFePo4 battery to do POTA activations. Very lightweight and can run several hours drawing ~20A and putting out 100W. Charges in about 3 hours. Good so far. I would only suggest slightly larger terminals.. connecting terminals from a radio or from my charger takes some careful effort due to these small screw terminals. Slightly larger terminals would make things better. ... show more
