    • Simply awesome for UPS use
Color: 12V 9Ah
Decided to take a gamble and buy this to replace the dead lead acid battery in our UPS. This battery is a lot lighter and has a lot more capacity than the old lead acid one. The UPS continues to run well and works thru any power blips that we have had and no errors with the unit at all. I definitely recommend this as an UPS replacement battery. ... show more

Great battery. I'm using it for a portable live well aerator. I get about 36 hours of continuous use out of one charge.

    • Update- Failed 1 year in
Color: 12V 7Ah
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. ... show more

    • So far so good
Color: 12V 7Ah
I bought 2 7ah batteries for my apc backup that is used for my aquarium. Batteries replaced the lead acid physically with no problems. The backup unit reported partial charge and after a few hours charge reports 600 to 800 minutes of runtime on my filter and lights. I have almost lost my fish due to power loss. I had to use a jug and move water from the sump to the display tank, and let it siphon down, which is a stressful pain I rather not repeat. I have had 3 year life from the original and last 2 sets of lead acid battery replacements. The idea of 10 years for only 2x the money seems like good value. Time will tell on this. ... show more

    • Almost meets rated capacity
Color: 12V 7Ah
Review Image by geo geo
It arrived with about 60% charge. I performed two full discharge/charge cycles before connecting it to a battery tester, which measured a capacity of 5.73Ah with a 10.00V cut-off and a 3A discharge current. The battery heats up slightly but not excessively. It's sufficient for my alarm system, where it remains trickle-charged at 13.6V. ... show more

    • Replaced my old APC BACK-UPS 750 Lead Acid battery
Color: 12V 7Ah
TL;DR: Replaces the battery on APC Back-UPS 750, works well. Lightweight alternative to the sealed lead acid battery in my UPS. My APC UPS 750 battery alarm started going off and would not stop, battery was dead. APC recommends you change the lead acid battery every 3 years, but mine lasted 5 years. Hopefully these new LIFEPO4 batteries last the 10 years as advertised. Works great on my APC BACK-UPS 750. You may hear a buzzing when you first replace the battery as the UPS charges it up. Once charged, the buzzing stops. ... show more
