Re: 3 into 2
Float charger is kind of like a low-end trickle charger, built to maintain the charge on a battery. I've seen them at stores for $20+, but that famous Chinese distributor, Harbor Freight, sells them for $5.99/ea. I bought a couple last year and used one on my motorcycle battery (Goldwing, naturally) since last summer and it still turned over last weekend. I'm going to buy two more and keep all batteries in the vehicles, but charged.
