Re: hennesey hammock coming in the mail
- 18Ah 12v SLA is a battery. 18Ah(Amp hours) means it is rated to
supply .9 amps for twenty hours. If your discharge rate is higher
than that you will not get quite 18Ah out of it. 12v is the voltage
of the battery in this case 12 volts. SLA(Sealed lead acid) is the
type of battery. SLA batteries are cheap but very heavy. If you
watch your charge rate, too fast heast things up and shortens battery
life, and don't discharge the battery past 80 percent, again not
exceeding the .9A rating to avoid heating, you can expect to get 300
or so charges from a SLA type battery. NiCd(Nickle-cadmium), NiMH
(Nickle-Metal Hydride) and LI(Lithium Ion)are other choices. All
store more power than SLA per pound of battery. Lithium Ion are the
lightest and the most expensive. You will also need special chargers
for the Lighter baterries.
