2. Nickel–zinc battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–zinc_battery

   Nickel–zinc batteries have a charge–discharge curve similar to 1.2 V NiCd or NiMH cells, but with a higher 1.6 V nominal voltage. [5]Nickel–zinc batteries perform well in high-drain applications, and may have the potential to replace lead–acid batteries because of their higher energy-to-mass ratio and higher power-to-mass ratio – as little as 25% of the mass for the same power.

   (3 cells): 4.5: Two 6–7 mm wide metal strips +: shorter strip −: longer strip: H: 67 L: 62 W: 22 This battery, introduced in 1901, was very common in continental Europe until the 1970s. It usually contains three B cells in series. In Switzerland as of 2008, 4.5-volt batteries account for only 1% of primary battery sales. [89] PP3, 9-volt ...

4. Zinc–bromine battery - Wikipedia

   en.wikipedia.org/wiki/Zinc–bromine_battery

   Zinc-bromine hybrid-flow batteries have many specific disadvantages: Reset: Every 1–4 cycles the terminals must be shorted across a low-impedance shunt while running the electrolyte pump, to fully remove zinc from battery plates. [3] Low areal power: (<0.2 W/cm 2) during both charge and discharge, which increases the cost of power. [5] [6] [7]

6. Golf cart - Wikipedia

   en.wikipedia.org/wiki/Golf_cart

   The first electric golf cart was custom-made in 1932, but did not gain widespread acceptance. [3] In the 1930s until the 1950s the most widespread use of golf carts was for those with disabilities who could not walk far. [4] By the mid-1950s the golf cart had gained wide acceptance with US golfers. [5]
