Power-Sonic PS-12550 SLA Battery

The search for portable power you can trust is over!

Power-Sonic introduces its 12-volt sealed lead acid battery line onto the market. The PS-12550 is a U terminal model, rated for 55AH and an internal resistance of 2.5 milliohms. Ideal for indoor and outdoor use, the PS-12550 is protected by ABS plastic, a hard outer shell built for increased impact resistance. AGM technology inside the battery removes free flowing liquid, excess heat, and increases overall current effectiveness. Ideal for alternative power sources, Power-Sonic sealed lead acid batteries are the preferred choice in portable power options.
