Now that's funny, have you listened to your countymen speak English? There can be a few non-dictionary words in there.

Now that would depend on how she looked.

i.e. in the specs shown.

If discharged at the 5 hour rate, the battery will reach a 60% Depth of Discharge (DOD) when the "End of Discharge Voltage" = 1.98V and this will be after 3 hours ("Effective Discharge Time").

Nice. Battery is rated 50Ah capacity at the 5hour rate delivering only 30Ah.

To 60% DOD! Any battery will give similar figures.

Note that this is a Lithium battery. The specs also show 4 hours to 1.93V if going to 80% DOD delivering 40Ah. And that is quite acceptable for Lithium.

If it was an equivalent sized FLA battery, the most you should count on getting from it is 25Ah. (50% DOD).

Ooops! that's a Gel, not Lithium battery.

I wouldn't be looking at taking that down to 80% DOD ( or even 60% on a regular basis).

My apologies. Disregard my last transmission. I thought the "data sheet" in the original post was real data.
You see. engineers talk with data to communicate the performance of their product in a data sheet and marketeers usually take this data sheet and convert it to sales literature. If we are analyzing the data from a sales literature, whatever conclusion we may arrive would be correct because there would be a convoluted explanation making the parameter in question totally vague and useless anyway.
If there is interest in the group I will explain further.
Fair Winds to all.
