Brought life back to my UPS battery backup for my computer. The max 20A draw reduces my UPS max load from 600W to ~450 w, but that’s fine for my use. Returned my runtime to about an hour from the 5 minutes my old batteries were down to. The UPS is still bad at estimating time left because the voltage curve isn’t what it expects. So after 20 minutes of predicted runtime, I get another 40 minutes+ while the UPS says 0 minutes remaining. If it all lasts 10 years, it’ll be money well spent.

Much lighter than SLA and lasts longer too

Works great in my Marcum LX6! Long life over the lead battery.

Perfect Transaction!!!!!!!!! Fast shipping!!!!!!Thanks!!!!!!!!!!!!!!!!!!!

Love these Batteries! This is my third battery purchase. Used 2 for a 24V scooter, now added a 3rd for a 36v ebike wheel. These things are such an improvement over SLAs! Carrying around 25 lbs of SLAs makes NO sense. At less than 10 lbs for 3 of these the bike feels so much better and if they truly are good for 2000 charges they will save money in the long run. My range is great now and I usually arrive back home with 3 battery indicator lights still lit!! Love them! Dakota Lithium has great customer service if you need them.

Very Good Battery. Well worth the cost. Now that I have a couple of months of use, I can honestly say: You will find this is an impressive battery if your experience has been only with Lead-Acid batteries as mine has been. This battery seems to retain its charge well when left “on shelf”. It has amazing high current output over lead acids, specifically 10 amp drain for 30 minutes w/o significant voltage drop (considering it’s size I’m impressed). No more lead acid batteries for me.

Xtra POC battery. Met my expectations for use on my POC.

This type batt seems to work well in UPS. Bought few more for other UPSs. Thx.

My testing showed it exceeded advertised capacity at 10.1 Ah with 97% charge efficiency. This battery actually exceeded it’s rated capacity in my tests. I did two full discharge/recharge cycles, and after a full discharge, it took 10.4 amp hours of charge, and after putting those 10.4 amp hours of charge into the battery I was able to pull 10.1 amp hours out. Generally, most batteries are advertised at their “actual”/rated capacity rather than “usable” capacity. For lithium batteries the “usable” capacity is generally only about 80% of the rated/advertised capacity. So I was quite pleased to see that I could pull over 10 amp hours out of this battery without pulling it’s voltage under 11.2 volts. (Dakota Lithium/Clean Republic lists the discharge voltage as being able to go as low as 9.2V, but it’s not good to discharge lithium batteries under 11V generally) For the charge efficiency, see the pictures attached: Putting 10.448 Ah into the battery yields 10.13 Ah out of the battery. 10.13 / 10.448 = 96.95% That’s incredibly efficient. On an SLA battery you’re lucky to hit 80% efficiency and only about 50% of the rated capacity is usable. So while this battery is about 3-4 times more expensive than an SLA of equal “rated” size, this battery is far more efficient, and gives you twice as much “usable” capacity as the equally sized SLA gives you and weighs 1/3 as much. It’s also rated for 2,000 cycles vs the typical 400-500 for an SLA. So over the lifetime of this battery you would need to buy roughly 8 SLA batteries at $25/pop ($200 total) to equal the lifetime usable capacity of this battery at $99.
