There is an inexpensive battery charger available at Harbor Freight if anyone is looking for one. It is "on sale" for $6.99 and only $5.44 with following coupon 83799384. Some may want to modify ends with ring connectors and a split connector. For the price, easy mod and will be under $10 complete. For those that don't care about taking off their seat, it is good to go. If your local HF doesn't have the ad with the coupon, just copy & print from this post or you can just show the cashier this post from your smart phone. Price is valid through Christmas Eve. Here is the direct link to HF

FYI: It goes without saying, but I feel I must point out that this will maintain your battery's charge in between infrequent rides vs charging a discharged battery. Hence the wiring mods may not be necessary. Use an automotive full charger or a more expensive small battery type charger to do that function.
I couldn't just leave the pic alone. It had to be a CB1100!
