Hi All.

Do any of you have any sick SLA batteries? I recently discovered that my t=
wo 9AH SLAs had become more than a little sick after sitting around for a w= hile and were not appropriately responding to charging. They were also imme= diately dropping to 9-10V with only 150mA of discharge current. I recalled = that I had been going to try something that I had seen in a YouTube video q= uite a while back. This is how it all went:

1: Carefully remove the top panel from the battery with a knife or screwdr= iver to reveal the rubber caps on the cells.
2: Remove the rubber caps.
3: Top up each cell with water. Yes, that's right, the video mentioned wat=
er but I would use distilled water.
4: Replace cell caps and top panel.
5: Charge.

I didn't have any distilled water left, so I used tap water after consider=
ing I really had nothing to lose. The charging process took longer than it = had recently been taking. The immediate voltage drop no longer occurred and=
now, all looks fine again. It seems that the main cause of this SLA "sickn= ess" is that they dry out.

I do have another battery that I labelled as usable, plus some I was given=
as no longer usable that I will also try to rejuvenate. Worth a try
