>>>New issue, since 6 days ago my charger (Sterilng) isn't marking as complete, just sits on charging light even after 8 hours, chair seems perfectly charged though and the charger isn't hot at all like it is during the first few hours, any ideas??
YES, leave it longer. It takes about 12 hours give or take a few to REALLY fully charge a set of lead batteries. 99 percent done after maybe 5 or 7. That last tiny bit is the difference between a sulphated battery or not. It must get a complete charge at least weekly (sunday morning?) to prevent this. This is why mobility chargers kill batteries. They usually shut off way too soon.
Or get a Hyperion, so you can SEE what is happening on your PC and watch, and control it on your laptop, with Remote desktop, or even your smartphone. Remote Desktop for your android? Email me for the best one!
