Old Sealed Pb battery

I got the 12V 17Ah battery out of my storage, but it wouldn't take charge that well.

Well I got an 50R dummy load, it got used as load, then added another one in parallel.

Charge using a regular car battery charger, then when it was full decharging using this load.

I have lost count of how many times i've done that so far. Though it seems to take longer and longer to decharge every time.

Now i have added in parallel 2 100R and one 160R power resisters.

It seems to how the power very well now.

With this load the current should be between ½A and 1A, not the highest, need to dig around to see if i have more power resistors laying around.
