It handles AGM, gel, and flooded lead-acid, runs a 4-step fully automatic program, and holds each bank at a safe maintenance charge. It comes with ring and clip cables plus mounting hardware. Right-sized for one or two batteries on a 25 to 30 foot boat.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Battery Tender 022-1002-DL-WH is a two-bank, 6-amp automatic charger for 12-volt batteries, and it's the kind of gear that quietly earns its spot on the bulkhead. You wire it in once, leave it connected, and it takes care of two separate batteries on its own. No babysitting, no guessing whether you left the charger on too long. It runs a 4-step fully automatic program and holds each battery at a safe maintenance charge once they're full.\u003c\/p\u003e\n\u003cp\u003eIt handles the three battery chemistries you'll actually run into on a boat or in the garage: AGM, gel, and flooded lead-acid. So whether you've got a sealed AGM start battery and a flooded deep-cycle, or a pair of matched AGMs, this charger reads each bank and charges it correctly. The two banks are independent, which matters. You can charge a start battery and a house battery at the same time without one dragging down the other.\u003c\/p\u003e\n\u003cp\u003eWhere does 6 amps fit? Honestly, this is the right size for one or two Group 27 or Group 31 batteries on a 25 to 30 foot boat, a bass boat with a cranking and trolling setup, or a couple of powersports batteries in the shop. If you're running a big 200-plus amp-hour house bank on a trawler, 6 amps is going to take its time bringing it up from a deep discharge. We'd rather tell you that up front. For maintenance and moderate top-ups on modest banks, it's spot on. For fast bulk charging of a large bank, you want more amperage.\u003c\/p\u003e\n\u003cp\u003eThe charger ships with two of Battery Tender's 2-in-1 harness cables. Each one gives you a quick-connect ring terminal lead and an alligator clip lead. Here's how we'd use them: bolt the ring terminals right to the battery posts for anything permanently installed, and save the alligator clips for a battery you're pulling in and out or charging on the bench. If you go the permanent route, hit those ring terminals with a little dielectric grease. The marine environment is hard on bare copper, and a dab of grease keeps corrosion from creeping into the connection.\u003c\/p\u003e\n\u003cp\u003eMounting hardware is in the box, so you can fasten the unit to a bulkhead or a shelf. Two things we tell every customer. First, give it room to breathe. The charger sheds heat while it works, so leave a few inches of clearance above it and don't bury it in a sealed lazarette or a tight enclosure. Trapped heat can trip a thermal shutdown and stop the charge. Second, this unit is not waterproof. There's no marine ingress rating on it, so keep it out of the bilge, off the sole where spray collects, and away from anywhere it can take on water through the vents. A dry, ventilated locker or a spot up under the console is ideal.\u003c\/p\u003e\n\u003cp\u003eA couple of rigging notes from the field. Run each bank its own negative return back to the battery rather than sharing a common ground, which keeps the two banks from cross-draining. And it's cheap insurance to add an inline fuse on each output lead close to the battery. The stock harness doesn't include fusing near the post, and any conductor tied to a battery should be protected. On outboards and other high-vibration installs, secure the leads and support them at the strain relief so they're not flexing every time you're underway.\u003c\/p\u003e\n\u003cp\u003eSet up right, the Battery Tender 022-1002-DL-WH is a set-and-forget way to keep two batteries healthy through the season and over winter layup. It's a proven design from a name boaters trust, it's honest about what it does, and it does that job well within its size. Just match it to the bank you've got, mount it somewhere dry with airflow, and let it work.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e4-step fully automatic charging program holds each battery at a safe maintenance charge once full\u003c\/li\u003e\n  \u003cli\u003eTwo independent charging banks, so a start battery and a house battery charge at the same time without one dragging down the other\u003c\/li\u003e\n  \u003cli\u003e6 amp charging current, sized right for one or two Group 27 or Group 31 batteries\u003c\/li\u003e\n  \u003cli\u003eCharges AGM, gel, and flooded lead-acid 12-volt batteries\u003c\/li\u003e\n  \u003cli\u003eTwo 2-in-1 harness cables included, each with a ring terminal lead and an alligator clip lead\u003c\/li\u003e\n  \u003cli\u003eMounting hardware included for bulkhead or shelf installation\u003c\/li\u003e\n  \u003cli\u003eSafe to leave connected during the season and over winter layup\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Battery Tender reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat battery types does this charger work with?\u003c\/summary\u003e\n    \u003cp\u003eAGM, gel, and flooded lead-acid 12-volt batteries.
