(Mechanoids): battery 12V lead acid gel sealed 40AH on green grass lawn in sunshine for solar PV power generation and storage system 3 DHD.jpg
D= [Jun 1, 2007]; S=3MB, 3264x2448; T=JPEG image [MIME:image/jpeg].

Rating: 54/100.

Key: D= file date of exhibit; S= size in bytes, XxY pixels, etc; T= type of exhibit; L= location/time or viewpoint of exhibit (if known).

  • battery = batteries, pile, cells, storage cells, accumulator, power store, energy store, DC (direct current) power, primary (single-use, disposable) cells, secondary (rechargeable) cells = See Battery University.
  • battery 12v lead acid = Lead-acid has low energy density compared to other rechargable types, but is cheap and robust and very well understood. Self-discharge is ~40%/year, good for rechargeable batteries, and maybe one quarter the rate of NiCd by comparison. Expected life might be 250 charge cycles and 10 years at 20°C, but halving in lifetime for every 8°C rise in ambient temperature.
