It’s not a jump starter—its role is maintaining, restoring and gently charging small vehicle and accessory batteries so they stay ready without overcharging.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Sigma 1 keep a battery healthy during long storage?\u003c\/h3\u003e\n\u003cp\u003eThe Sigma 1 uses a nine‑step charging algorithm and floating charge capability to hold batteries at optimal voltage without damaging them. Once connected, the charger monitors voltage and adjusts charging current automatically, supporting overnight or extended maintenance with no babysitting required.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAutomatic nine‑step charging to protect battery life\u003c\/li\u003e\n  \u003cli\u003eFloat\/maintenance mode for long‑term storage\u003c\/li\u003e\n  \u003cli\u003eLow 1A current prevents overcharging smaller batteries\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan Sigma 1 recover a drained or sulfated battery?\u003c\/h3\u003e\n\u003cp\u003eThe unit includes a desulfation function and a Force Mode for deeply discharged 12V batteries above 0.3V (and repairs when voltage is above 2V).
