A 12V sealed battery with an acid 6-pack.
Lead-Acid batteries: These batteries are sold dry and sealed, for freshness and maximum strength. Battery acid must be added before use. It is included with the battery, unless stated otherwise. Read the instructions with each battery. Wear eye and skin protection. Use baking soda to neutralize spills.
Battery Charging: All lead acid batteries need to be kept charged, at least every 2-3 months, or they will become weaker and weaker with age. After 2 years of sitting they are less than 25% of their original strength. That’s why these batteries are sold dry. For a lead acid battery, life begins at the moment the electrolyte (dilute sulfuric acid) is added.
Volts, Amps and Hours: The last number means the amp-hours. A 6N2 will deliver 2 amps for 1 hour (or 1 amp for 2 hours). A 6N4 will deliver 4 amps for 1 hour (or 1 amp for 4 hours). Bigger batteries produce more amp-hours.

Cateye 5-pack of vintage-size C-cell NiCads 5.5V n.a.
These turn signal kits were a popular accessory on 70’s mopeds.
But there was not any extra electricity so they were not too bright.
All of the NOS batteries, made in 1980, have become weak or dead.
Modern C-cell NiCad batteries are wider, and do not fit in the box.
They can be soldered in series, and mounted on top, or elsewhere.
