Review: Not a lead-acid drop in - This is a remarkable product. The listing on desertcart and the product manual does not do it justice. Unfortunately many buyers will have an unsatisfactory experience because they are expecting it to work like their familiar 12V, 7AH gel-cell / absorbed mat batteries. 1) because LiPO technology is dangerous when abused, these batteries have internal charge management and cell protection circuitry. Best to have a charger that supplies 15 ( or 14.7 ) Volts: the internal management will terminate the charge cycle at the correct internal cell voltage. The may accept a charge rate of 4A, but a current limit of 2A would be more reasonable and likely to make the battery last longer. I use a microprocessor controlled charger. 2) Discharge Current claimed up to 8A ( ? tolerates instantaneous 3C or 21A ? ) again is abusive to the battery chemistry. 2 to 4 Amperes would be more reasonable. Better yet: less than 1 A. From the listing - buyers might expect good performance in kid mini-cars, a variety of motorized appliances or tools, even starting motorcycles / lawn tractors or trolling motors. And charging the battery from the wall-wart that came with the toy. It might work, it might work for a short time, it very likely will not be satisfactory. This isn't the product's fault and no reason to leave a bad review. The special qualities of LiPO / LiFePO4 chemistry are very light weight, low self-discharge, good cold weather performance, long lifetime / many charge cycles, stability at partial charge states. Ideal for communication and data link equipment, alarms, low-draw LED lighting on a small sailboat or cart ( like a tourist rickshaw ), a very small UPS, certain camera equipment, some medical equipment ( like a portable oxygen concentrator or medical telemetry IF APPROVED FOR THAT USE BY THE MANUFACTURER and/or FDA ) In overload or over-heat conditions, expect the internal battery protective and management circuitry to kick in and the battery to "stop working" These are great, long-lived 12V batteries, but they aren't like lead-acid technology and will probably disappoint as drop-in replacements using some chargers - especially vehicle charging systems. I'm buying more - these are at a good price - to power various electronics. If I am a "five star" user ... these will give me "five star value". Hopefully this review will save you some disappointment and inconvenience.
Review: Good UPS replacement battery - This was a drop-in replacement for a lead acid battery on a UPS - CyberPower CB650 VA Although the chemistry is different, it works because power management is built in. On top of that it is remarkably lighter, has much longer life, and for my low power Dell system provides more than 3 hours of run time. (an enhanced Dell OptiPlex 3070 Desktop Computer - Intel Core i5-9500T)
