Review: Scam product - What great product i bought depending on its reviews but it just last for 3 seconds and then it blow up … cheap quality Review: Burned up as soon as I plugged it in. - No indication on if this is 110v or 240v. I bought it, plugged it in and it burned up, smoke pouring out of it. This seller needs to be investigated for fraud. Omitting something is the same as a lie. Only one star because there was nothing lower to choose from. ## Features - Stay Charged: Battery Tender battery chargers and maintainers provide a full charge to your powersport vehicle’s battery before switching to float mode to maintain proper voltage levels for safe, long-term storage - Extend Battery Life: Compatible with all 12V lead-acid, flooded, AGM, and gel cell batteries.
