ExpertPower12V 5Ah Lithium LiFePO4 Deep Cycle Rechargeable Battery | 2500-7000 Life Cycles & 10-Year lifetime | Built-in BMS

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.

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!

This battery fits perfectly and it has the F2 style connector (wider than the F1). This battery is also quite a bit lighter than the lead acid original, 1Lb 4oz vs 3 LBs 2.25 oz. My UPS is working and it's lighter to boot.

This is a tough one...on one hand, the quality is excellent, the capacity is accurate, and it seems to be made very well but it’s also still a bit cost prohibitive for a lot of people. It’s getting better and the fact this will cycle thousands of times instead of hundreds (as in the case of cheaper but much less longevity). This seems to be made very well and it’s heavier than the 16 amp hour battery that I got (a much cheaper version from another brand made overseas) but I think the capacity is much more accurate here. It charges quickly, puts out enough power for me as a part of a building battery bank of LiFePO4 batteries, and it’s dependable. It’s also got a good warranty. If you treat it right (and most LiFePO4 batteries) they should cost about the same or just a pinch cheaper than sealed lead acid if you don’t over disacharge them. There is a supposed very good BMS built in and that should help it last quite a while. It’s not the most economical choice per amp hour but it’s checks all the boxes of a quality LiFePO4. I’d buy a 100 amp hour version if I could but it’s just not in the cards for me, economically...maybe one day (I would recommend it if you need that size and it doesn’t pinch your walllet too much to do so). The bottom line? This is a very high quality LiFePO4 battery that is dependable and gives the rated capacity and a little more (with a low discharge rate). I’ve been using this with my solar setup to run some strand lights in the backyard for a few hours and it’s been a champ.Pros:Made wellHits rated capacity (it’s a real capacity and not marketing)Charges wellCame charged mostlyCan use almost the whole capacity (cannot do that with SLA without damage)Good BMS (battery management system) built inDischarge rate is super consistent for most of the capacityShould last thousands of cycles if not discharged more than 80%. I’d think it would still last 2k cycles at a very deep discharge rateCons:Not cheap...not in any sense of the wordOverall, I’d “buy once, cry once” instead of a cheaper alternative and maybe having to buy multiple times.

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.

I bought this a year ago. I used the battery once, worked fine. Then I charged it and stored it in a cool dry place. Now it does not accept a charge and has no power. I did check both my charger and the battery with a multimeter. Charger works battery does not charge. What a waste of money.

Larger physically than the replaced battery so it would not fit in the compartment of my Uniteruptable Power Supply for my computer. Also larger in capacity and with deeper discharge characteristics should keep the computer running longer than the gel cell batt. Lithium batts have longer life and I believe he charger should still work fine with this battery 1 month so far. I will be getting an even larger batt and updating my other UPS with a lithium batt soon.

Pros: This battery boasts impressive longevity with a life cycle of 2500 to 7000, making it a great investment for those looking for a durable solution.Cons: On the other hand, the limited time to power could be a concern for those who need a long-lasting source of energy. With only 5Ah of capacity, this battery may not be enough for extended use without recharging.I strung three in parallel to power a pool temperature monitor and it will last over night. I started with 2 and it wasnt enough due to a cloudy day so I wanted to add another 5 ah to help it last on those types of days.Overall, the ExpertPower 12V 5Ah Lithium LiFePO4 Deep Cycle Rechargeable Battery is a solid choice for those looking for a battery with a long lifespan. However, its limited capacity may not be suitable for everyone's needs.
