I have a spot light that uses a 6V 5Ah lead sealed battery. I have lost the charger. What power charger(volts and amps) should I get to charge my light?
Get a charger for 6V-Lead-Batteries (actual voltage should be somewhere at 6.7 to 6.9 volts, roughly; the companies who make the chargers can usually be trusted to get it right ).
The current for your battery should be at 0.5 or 0.6 amps, resulting in a 8 - 10-hour charge cycle.
I would recommend a charger with automatic shutdown, so your battery won't get damaged. When the charger doesn't have that feature, make sure that the battery isn't hooked up too long; the duration of the charge cycle normally is the capacity (5Ah) divided by the current (p.e. 0.5A) -> 10 hours.
- don't use a higher current (unless you know exactly, what you're doing), the battery might overheat while charging and explode.
- while charging, check the battery's temperature. make sure it doesn't get too hot.
- The more expensive the charger, the more sophisticated it should be (some have features like battery regeneration, auto-shutdown, overheat shutdown,...). Just make sure you don't by the best, if you just use it twice a year
