To get the most lifetime out of this battery, what minimal voltage should the battery be drained to? E.g. 12.5V?

I would not take this any lower than 11.5 A full charge is 12.65. I use them for my solar panel and charge them up to 13.65 to 14.0 volt and will sit at a float charge of 13.65. You should get about 1500 deep cycles or 4 to 5 years at least providing if they are inside or out side in the heat

Yes20v max and 12v max are the only batterys that work in that ratio.18v dont work in that ratio.But the reception aint good.

3100 mAh is the capacity of the battery not the output. So no it shouldn't hurt it, just make it last longer.

Yes, I would always recommend a voltage reducer to pull 12v from the entire battery pack. This will keep one or two batteries from failing before the others in the set due to more frequent draining.

The one that I have is reliable and reasonably accurate down to about 80V. Below that voltage it rapidly becomes inaccurate and the display flickers. I do not know the maximum voltage. (I tested it with a variable-voltage transformer.)

I'm not sure. I just got the closest thing to what I had before. Don't remember if this was the same voltage as my old battery. I got this new battery over a year ago & it's working fine.

Not sure about the low voltage shut off, but I never disconnected mine, just shut it off, had no issues with a low or dead battery.

I really don't know. From what I understand with any battery you should fully charge the battery before each use and you should fully let it die (don't keep it plugged in while you are using the computer at the same time). Not that many people actually fallow these suggested steps but they help to is that to elongate battery life.

It depends largely. There are instructions in the box on how to care for the battery, but...basically it has to be charged to aat least 12.6 volts. It would not hurt to charge it fully, that's what I did even though mine read 12.8. As for chargers, use a charger capable of charging an agm battery. I charged mine at 15 amps bit over read lower is better. Not sure, but mine is going strong as has for The 3 months I've owned it

The first time I allowed this battery to drop below 50% was after 1 year 4 months of ownership. And, now it wont charge to above 10 volts. So, yeah... I disagree based on long term use and experience with the product not just a generalized view based on manufacture information.

Hello Ras, no there is no minimum number but in order to be able to do some thing worth while I would say at least 4 big 125 Amp batteries and 10 to 12 for heavy work and make it useful to save on electricity!! The moment the voltage drops below 11.5 it starts making noise to shut it. Ajay Madan

I am using this for alarm system backup (line power failure) so it sees infrequent use. Still near 12v after a year.It will probably go 3 years but I'll swap it @ 11 volts-open.

The battery is 12v max litheon. BAT 411, 10.8v/12v max. This is information directly from the battery.

From what I understand it to say, either in the manual or the small print on the box, the voltage (20V) is what is read on a volt meter WITHOUT a LOAD, but once a load is applied, it drops to 18V. So either battery I am to Assume, will work on this battery.

Depends on what the lowest voltage your device can function at. The battery pack voltage is lower than what you specify. It actually puts out about 12.2v when fully charged but will drop to around 10.5 to 11v as it discharges. It is not a true 12v battery pack by design.

I've had mine for just about a year... I'm noticing just a bit of drain on the battery life. I'd say it's a strong 10-15 minutes. That's about all you should expect out of 6V. At less than half the price of a 12V I still recommend it. If they had one with a crevice attachment and at this price I'd buy stock.

I don't know about battery life as I've only used it with the AC adaptor. There is a sticker on the back of the unit which says: 12v = 600ma. I assume that must be the voltage and current required to power the unit. That matches the rated output of the adaptor.
