Lead Acid Batteries

[temrich]

Hello all. I have a DR 10W HID and I just bought a new lead acid battery for it. I charged the battery for about 15 hours. I tried to do a burn test on the battery and it began to flicker(not bad though) after an hour and a half. Wodering if anyone had any idea what the burn time should be, did I not charge it long enough, and any other helpful advice. Thanks. Travis

Was it a PowerSonic?

I have a 2001 Wreck 1 canister on a 10w that originally used a PowerSonic 2.9aH battery. When the batteries (I had two) became old, I ordered two more from a local battery wholesaler. When they came in, I noticed they were something like 2.1aH, although they were the same size as the old 2.9aH.

If I got two hours out of a 2.9aH, I'm guessing I'd only get about 1 1/2 from a 2.1aH.

Maybe this happened to you?

I don't remember what brand I ended up getting, but they were 2.9aH bought from arcade-electronics.com.

D'oh. Too late.

The new battery I got is a Power Sonic. I just went and looked at it and it says 2.9 amp h. So, maybe I need to charge it a bit more? Maybe 15 hours didnt give it a full charge. So, seeing as how it is a 2.9ah battery, should I be getting close to 3 hours of burn time? Thanks
here is the link to the site where I bought it

Technically, you should get 3.48 hours, but I never got more than about two before it started flickering.

Makes sense. I had two batteries and one started only giving me 30 minutes of burn time. So, I bought the new battery and I guess I just started to get freaked out when it didnt last as long as I thought it should. Any suggestions on a charger? I have one that has a light that is red when charging, goes dim, and then at some point goes out. Is that a good charger? It came with the light when I bought it. Any suggestions on a different style?
