The 210AY multiple battery connector is a simple, safe and affordable way to connect 2 batteries simultaneously for easy battery maintenance. Use in conjunction with BatteryMINDer® units designed to maintain multiple batteries. Features 3 in-line, replaceable 15 Amp fuses to keep each connection protected against potential short circuits. Each end features an automotive SAE "bullet" connector with cap. Connect the duel cords to your batteries via Ring Terminal Assembly, Battery Clips, or Insulated Battery Clips (sold separately.) Includes two 15 Amp fuses, to be used to replace the fuses in the battery connector assembly (Ring Terminal assembly or Battery Clips) if they are not 15 Amps. Combine with additional Y-connectors to add even more batteries (up to 8 batteries, depending on the unit) to capable charger systems.
Never connect two or more batteries together before fully charging each individually and checking their condition. Failure to fully charge each battery and check their condition can result in a serious safety hazard.
I have used the batteryminder to maintain my boat, ATV, lawn mower, and couple other batteries, fresh and ready in the offseason. I could not find this 2 way splitter locally, and found Battery Mart online. Shipping was quick and product was exactly what I expected!
