Quick Overview

The Deka 8G4D is a maintenance-free Gel Cell battery that combines true deep cycling ability with sealed, spill-proof construction. Made in the USA


Exceptionally reliable, these long-lasting 12 volt batteries are very resistant to hot and cold temperatures. The completely maintenance free, sealed construction eliminates periodic watering, corrosive acid fumes and spills. Electrolyte will not stratify, no equalization charging required, allowing faster recharge. Increased durability and deep cycle ability for heavy demand applications. Less than 2% per month stand loss means little deterioration during transport and storage. Transports easily and safely by air. Advanced Made in America technology with the most modern computer-aided design and manufacturing techniques combine to make Deka's Sealed Gel Batteries the standard by which all other batteries are measured.
Deka Gel Cell Batteries are ideal for remote solar applications such as security systems, remote telemetry, LED hazard obstruction FAA lighting, SCADA systems, pipeline monitoring, oil and gas wellhead monitoring, WiFi and WiMAx and other wireless applications

IMPORTANT CHARGING INSTRUCTIONS: WARRANTY VOID
IF OPENED OR IMPROPERLY CHARGED. Do not install in a
sealed container. Constant under or overcharging will damage
any battery and shorten its life! Use a good constant potential,
voltage-regulated charger. The open circuit voltage of a fully
charged 12-volt battery is 12.8V at 68°F (20°C).

Batteries manufactured in polypropylene cases and covers.
Batteries manufactured with gray case / gray cover
unless noted.
