12 Volt Batteries

• My FAQ: UPS Batteries Internal Resistance
• Wikipedia reckons one should not exceed 14.4 V else it will gas, so I measured my (standard commercially bought car domestic use) chargers:
  • Charger: Bosch Battmax (black plastic case)
    220V 160W. 2 Switches: 6/12V & High/Low
    Switched to Low: 14.7 V, Switched to High: 16.1 V.
  • Charger: Belmar Startrite (Orange painted steel).
    Only 1 Switch 6/12V.
    16.5 V
  • Charger: Old UK (ras@) not yet measured.
  • Comparative voltages of both chargers above, alternately charging same battery (nominal 12V 17Ah, but probably I've now put a nasty cheap under rated Chinese battery in there now) of my black car jump start kit, in same fairly well charged state (after allowing 10/20 secs for battery voltage to climb & settle).
• Caution liquid acid batteries are cheaper than Gel batteries. Liquid give higher starting current when helping jump start a car battery, but I prefer gel in a portable jump start kit.

    Normally in my shop they have flat blade contacts, Not the screw type shown here. For some UPS that screw type would be impossible, fuse holder relies on shape. For some jump star kit it might not matter.
