When does a battery

I cleaned it and right now it's reading 3.9 without a load and 3.6 with. So hopefully that was the problem. These batteries will be a year old next month so I'm going to order some new ones soon.

That might be it. I just tested out my AW IMR in the pv I'm using and then on the multi-meter. Reading was almost the same.

I should get a multimeter. I've only been using the provari meter.

If you have a Harbor Freight near you they usually have a multimeter available for about $5 or less.

Comes in handy when re-building attys too.

I would say it is a combination of not cleaning and the batteries getting old. From what I understand the Provari shuts off before the battery is completely dead so it keeps the battery going strong for a longer time. I believe it is recommended to charge these type of batteries before they are completely dead. My Provari is always at 3.2 before it dies.
