I sent an email to TalentCell last night and had a reply this morning. They stated that the max amperage the battery can handle for charging is 12A - I never came anywhere near that. My first email to them was short, and did not contain much information. Their reply was about the same, as expected. Dear Robert, Maximum charge current is 12A. Please check if charging current more than 12AH. Best Regards Name Removed TalentCell Technology I sent a follow up email with details about the charger, monitor, and load, and explained what I am seeing the battery do. Hopefully they will send another email and let me know what they think is going on.
