Product Details

Power-Sonic PS-640 Sealed Lead Acid Battery 6V 4.5Ah

Power-Sonic PS Series rechargeable sealed lead acid batteries are leaders in their field. They adhere to industry-standard form factors, but lead the way in high tech features and competitive pricing.

Each battery uses valve regulated, spill-proof construction, and is made of rugged ABS plastic, allowing for safe operation in any position. While these batteries have an extended shelf life and may be quite useable up to one year after being charged, Power-Sonic recommends recharging at least once every six months for maximum battery life. The PS Series are humidity-resistant and can be discharged over a temperature range of -40° F to +140° F. Connection by F1 quick disconnect (0.187" x 0.032").

Rated 5 out of 5 by from Customer Service at its best!!!Not as much the item but the service and prompt shipment. I've been a customer since the 90's and have always been pleased with the prices and products but I ordered these batteries on monday at 4:05, after the daily shipping deadline, and the CSR rushed my order and got it shipped that day, I received it the next day when I needed it and the shipment cost was very reasonable. I would definately recommend the site/store to a friend. Time will tell about the quality of the batteries but I expect to be satisfied.
