My Odyssey needs to be woken up
I have a funny phenomenon with my three year old Odyssey PC680 battery. It can't pull the engine around even though it's been on maintenance charge. But if I then put it on charge for just ten minutes, it's suddenly like a new battery. Same thing if I manually start the engine and then just let it run for 3-4 minutes.
What is happening in the battery? It can't be that it charge in that short time. It seems like it just been waked up with a failed start attempt and a very short charge.
I usually change the battery when this happens and I think I'm on my fourth battery. But it feels unnecessary to have to change the battery when it really only needs to be "awakened" to work. Is there anything I can do to make it work better?
