ExpertPower 12V (12.8V) 5Ah Lithium LiFePO4 Deep Cycle Rechargeable Battery | 2500-7000 Life Cycles & 10-Year Lifetime | Built-in BMS

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.

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!

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!

Replaced the Long Way 6FM5 lead-acid battery in my Fishman Loudbox Mini Charge with this battery. Easy replacement, fit perfectly in the bracket, and worked out of the box. The original battery couldn’t hold a charge anymore and the orange charge light would flicker rapidly when plugged in. After replacement of the battery, the amp is working just like new. Also, this battery is significantly lighter than the original!

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.

This battery has successfully maintained our security system in our last power outage that lasted for about 6 hours. Usually all the lead acid battery, even when it’s brand new, did not stand a chance of lasting more than 4 hours of power outage. But this lithium did the job. One thing you want to make sure before installing it is to find out your system wattage and voltage, a little off is okay. Also make sure that you use a separate lithium battery charger (my battery charger’s brand is Tenergy) to make sure that this battery is fully charged up before installation.

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

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.

Me sorprendió la verdad lo que dura la pila .. Uso focos que generan 6w y la verdad me duró bastante tiempo me encantó la batería pronto aumentare de tamaño comprando una mas grande pero x lo pronto esta esta muy bien para iluminar y algunos electrodomesticos que no consuman mucha corriente eléctrica.
