- What is the difference between the SigmasTek 12V 100Ah SLA and the SP12-100 two-pack?
- They are the same 12V 100Ah sealed lead-acid battery. The SP12-100 listing ships two of them, so you pay one shipping charge and get a matched pair for a 24V series bank or a larger 12V bank.
- Where is SigmasTek cheapest?
- It varies by listing and by shipping weight, since these batteries are heavy. The product page compares each store's price and shows the price history, so you can see which store is lowest right now and whether that price is above or below its usual level.
- Does SigmasTek run sales?
- SigmasTek does not promote its own seasonal sales the way consumer brands do. Discounts usually come from the retailer, so watch the price history on each listing rather than waiting for a brand event.
- What are SigmasTek batteries used for?
- The 12V 100Ah block suits UPS and backup power, off-grid solar with a charge controller, trolling motors, mobility scooters and RV house power. Check the required charge profile, since SLA needs a voltage-regulated charger and should not be discharged below about 50% for long life.
- What is the return policy on SigmasTek batteries?
- Returns are handled by the store you buy from, not by SigmasTek, and lead-acid batteries are often excluded from free returns because of shipping rules. Check the seller's return window and whether return shipping is covered before ordering.
- Are there SigmasTek discount codes?
- Deal.ai doesn't list SigmasTek discount codes. It checks what SigmasTek products actually cost at every store, so a real markdown shows on this page as a deal as soon as it starts, and each product's page has its price history to tell a sale from its usual price.
