Put these batteries on my gate opener and deer feeder. Have been running strong for a year now. Would purchase again. You do have to charge them before you use. They are super light weight compared to traditional batteries.

Light as a feather. I couldn't believe it. I have this monster flashlight that uses these batteries. I figured for a few extra bucks, why not try this lithium battery. Wow, what a difference. Very powerful and incredibly light. I would give it 10 stars !

I purchased this to replace a battery in a portable speaker that came with a sealed lead acid battery. Weighs 1/4 of what the old one did! I used to get about 15 hours of use on the old one at 3/4 volume and I’ve been running this one on the first charge for about 20 hours so far and have not lost one single bar of charge! Very impressed for the price

Update- capacity of the battery started fading after 6 months, and is now completely dead after 1 year. Within 6 months, battery life had faded from easily a full day to only a couple hours. Now, battery life is about 10 minutes at low volume and it dies immediately if turned up. The speaker indicates it never goes above 1 bar charge. The original cheapo lead acid lasted over 2 years, this supposed improvement only made it 1. Don't bother. Original review below. Have a Ecoxgear Boulder+ speaker that's a couple years old and the original sealed lead-acud battery life had faded to only a couple hours at low volume. Figured might as well upgrade to a lithium pack, this physically was a perfect fit, however it arrived completely dead out of the box. Only 0.2v measured across the terminals. It's common on 12v replacement packs like this the BMS will go "dormant" if u used for a long period of time, or the battery is run too low, preventing over-discharge. Generally, applying a charger will boost the voltage and "wake up" the battery. However the built in charger of the Ecoxgear speaker was only supplying about 13.8, which apparently wasn't enough to "wake it up".on the pack it says charge voltage 14.8, which is higher than most appliances designed for SLA batteries will provide. The shade tree trick is to just jump it to an 18v power tool battery for a couple seconds. This did the trick, and woke up the battery, now showing only 9.5 across it, but it started accepting charge from the speaker. After about 8 hours it was showing fully charged and 13.8v across the terminals. So far so good, speaker works fine and was on for several hours at fairly high volume and didn't even lose one bar of the battery gauge, where with the old battery it would have been dead within an hour. The other quirk of lithium replacements is the battery meters is generally calibrated for approximate charge % based on the voltage curve of the original lead acid, while these lithium packs have a more or less regulated output voltage for the majority of the capacity, only dropping off as they're nearly empty, so the appliance may show 100% charge for like 90% of the capacity, then rapidly ticking toward empty right at the end. While somewhat troubling the battery was essentially DOA, with zero instructions or anything that it may be "dormant", LiFePo batteries are generally very tolerant of deep discharge, moreso than li-ion. If you have a battery charger specifically compatible with automotive 12v lithium batteries, they generally have a "boost" button or will automatically apply a high voltage even if none is sensed, but chargers intended for lead-acids usually won't supply charge unless some voltage is seen, or may not supply high enough voltage to "wake up" the pack.

Got this to replace alarm system back up battery for tired of replacing AGM 12v battery after a year or so. Very light weight. Charged with my Odyssey 3 tiered voltage charger. Was checking at ~14.6v or so after 24 hours but never did go into normal float or standby mode. That charger is made for AGM and lead acid types and this new battery the mfg has stated a specific charger may be needed. I have anti-sulfate pulse and various chargers, again for AGM, lead acid and deep cycle batteries. Hooked the new battery into alarm just fine. Time will tell how well it last and or if it accepts a trickle charge or not from the alarm system? If battery goes into a standby mode and shuts down on its own then an alarm system backup is not for it.

First impression - The unit is much lighter than the traditional battery which is a big plug. The UPS unit's weight reduced a lot. Next, let's hope the life span of this unit would last longer than 4 years which is generally what traditional battery would last.

This battery is the exact same size, voltage, and amp hour as the original, but is half the weight. You do need a different charger than the original that came with the fish locator, but definitely worth it.
