I thought I watched a video where Dave gave a presentation on the efficiency of lead acid batteries. (I might be mistaken.) In the video Dave talked about the heat loss in charging leas acid batteries, up to 20% and the heat loss when discharging which iis also about 20%. So between charging and discharging lead acid batteries up to 40% can be lost as heat.
Anyone remember the video and can offer a link? Or was this someone else.
Thanks

I think round-trip efficiency is more like 80%, but there may be other factors mentioned in the video.

I though Dave a really nice video explaining it. And it was 20/20 totaling 40% loss.
