Motorcycle battery problem?

Question

I accidently left the key in the on position for about a week on my bike. Before this the battery was in excellent condition and was kept on a battery tender. I went out to start it and it was completly flat. Is is safe to use the tender to charge it back full or did i kill the battery capacity forever?

Answer 1

Charge it back up and it will likely be fine.

Answer 2

a float charger only works on a battery that has a low charged. buy a new battery.

Answer 3

Your battery should charge back up fine on the battery tender unless it is over 3 to 4 years old. At that point it is worth the $50 (walmart) to $180 (BMW gel bat) because the bike will leave you stranded someplace besides your comfortable home.
