<p>Thanks for making me think through some items, Loren.</p>

<p>It is a Model PS-12180 (left out the "1"). While PS recommends their own chargers, the charging cycles spec'd are within the range of my charger. More interesting is the shelf life specs on their tech sheets - 80% at 6 months on the shelf. My battery was made 3/21/2020, and I purchased on 6/19/2020, so it's 7 months old and was never charged by me. 80% of 13.45 volts is 10.76, right about where it was reading. I may do as…</p>

I may do as suggested above and put it on a nice slow charge for a few days.

<p>I'd charge at whatever rate, and however long, the manufacturer recommends. What is the shelf date on the battery? If the battery sat to long in a discharged state, it could prevent a battery from holding a charge. The lead plates sometimes need an equalizer charge, but use caution. </p>

<p>I would slow charge it for at least a few days to give it a good base charge. Then, always keep it on a maintainer/power supply when powering the avionics/lights/etc..</p>

Don’t recall the model. I’m at the drs so can’t chk. 1280? It’s about 8x7x2.5. Sealed lead acid. Few is relative. May have been 4-6 hrs. I use a taper charger. Starts at 12A for cars, but this started at 2A tapering down time barely above zero.

<p>Which Powersonic battery are you using? Is it a lead acid battery or lithium? If lead acid, is it a sealed battery. A few hours is not typically enough time to properly charge any battery. Also, are you using the proper charge for that battery?</p>
