Lead-Acid or NiCd Batteries? |
 | | Overall, NiCd batteries are at least as inexpensive, and probably actually somewhat less expensive a source of power than SLA batteries if you are using them frequently, over the course of their total life. |
 | | NiCd batteries are, overall, about 30% lighter for a given amount of power capacity than SLA batteries. |
 | | NiCd batteries lose about 1% of their charge per day when sitting on the shelf, due to internal "self-discharge". |
