3. Battery Tender Junior $39.95
If dad’s always busy with honey-dos and running the kids to and fro, he may not get to ride his motorcycle as often as he’d like, but he can keep the battery fresh with the Battery Tender Junior. The Junior version works just like its larger and more expensive counterparts with a complete four-step charging program (Initialization, Bulk Charge, Absorption Mode, Float Mode), is compact enough to reside in small spaces others can’t, and is still able to reach the battery via its 12-foot output cord. The spark-proof, reverse-polarity-protected charger is good for lead-acid and gel cell batteries. Available at the BatteryTender.com website (except, for some reason, in California) and various other online and in-person retailers.
