EEMB 12V 9AH Deep Cycle Rechargeable Lithium Ion Battery Replace SLA Lead Acid Battery Built-in BMS for Kayak Fish Finder (with Charger)

It works, but I can't speak to how long it lasts compared to the original battery. I knocked one star because I can't seem to get a full reading from the battery no matter how long it charges for. This means I never no if it's full or could use a charge till it's low or dead. My device only has 4 lights to represent battery status and it only ever lights 3.I will update if I have any long term issues.

I couldn't believe how light this battery was in comparison to a standard battery. I used this to replace the batter in a large bluetooth party speaker. It fit well and powered the speaker just as it should. I am looking forward to the weight reduction as well.

So far, these are great! I used them for a powered dolly that climbs stairs, Power Mate. It used two of these. They are working and are much lighter and slightly smaller than the original acid type battery’s. I recommend these.

I bought this to replace a sealed 7Ah lead acid battery I use in my kayak for a fish finder. This has more capacity and is a small fraction of the weight. The battery box feel empty. I'm stoked that lithium batteries are down to reasonably acceptable prices now!

I bought this to replace the terrible lead-acid battery in a portable speaker I bought and I've used it many times and it still has plenty of juice. Very satisfied.

Used in a 24v pair for uninterruptible power supply. Super and superior battery replacement solution.

Battery does NOT charge. I’ve had it plugged in for DAYS and it doesn’t read fully charged. It does work but I have no idea how much charge it’s carrying. I tried emailing the manufacturer and received no response.

This batter looks USED!!!! $68 for a second hand product. This battery loses charge when not in use and nothing is connected. I know know I have to test everything the day it arrives. Save your money for a real battery.
