I actually put this battery in my Honda generator Work Great!

I was a bit skeptical about the LiFePO4 batteries because I used to have bad luck with older versions of Lithium Ion technology. But I'll have to say that these newer batteries made me a true believer. They might cost a little bit more, but rest assured that the price is worth it, in threefold. Not only are these batteries lighter, but they also pack an extra punch, they are able to handle high demands. Not only do they charge faster, but the charge lasts longer, and even if the battery is depleted, also has a great recovery rate. Onboard technology makes sure that overcharging, undercharging, and overheating is not an issue. You really can't go wrong with these batteries as an upgrade for your device.

So far, very satisfied with the the form factor and performance of this item. It fit the cabinet correctly, and has the exact same dimensions as the lead-acid battery it was bought to replace. (Installed it this morning in a home security system.) The battery only fell short in one minor aspect: the terminal blades that connect it to the slide-on clips of the security system were a bit too wide, and did not fit without my altering them with a pair of high leverage electrician's side cutting pliers. After that, everything seems to have gone smoothly; the system is not complaining about the battery, and it seems to function perfectly. We'll see how well it holds up has the months of service accumulate!

I replaced the SLA battery in my camping shower and it worked perfectly. Since it went into a camping shower the weight reduction was a huge plus for remote locations and my back. You will want to check the specifications on your device's charging voltage, but if it meets the requirements this should be a great replacement for an SLA battery. I just used it on a trip and there were four of us taking showers every day (three days total), washing our hands, and washing dishes, it never ran out of power.

Even though charging is not ideal for LiPo from my control box it is very close. So far with about 6 months in the field all the batteries that I've put out there have test clean. Will need more time to see if these will hold up, but they should way out perform the old seal lead batteries!

Great investment for power on my kayak. This sits inside a latched console on my kayak and is wired to a project/connector box. I used heavy-duty Velcro to keep it in place. 12Ah will run my current setup all week. I got the extra capacity for future use when I upgrade my fish finder/GPS. Being a sealed battery, you have many mounting/placement options. I never even see it - the space it is in was not reachable while fishing and, when I get home I just plug the charger in to the project box. I can go on several day trips without needing to charge it. Also, it can sit for weeks or a few months without a trickle charge. Be sure to use a Lithium specific charger.

Easy to replace and works great! Its also stores measurably more power than the original and should have a much longer life than the previous lead-acid battery.

Bought this battery on February 15th, 2021. Worked amazing for powering my kayaks fish finder and lights. Great battery in that sense. Fast forward to February 21st, 2023. Battery refuses to hold a charge. in less than one week after the 2 year manufacturer warranty ends the battery is broken. So sick of companies pulling this crap.
