Description

Upgrade the battery in your vehicle with the Odyssey Battery Performance AGM - Group Size 94R H7 (850 CCA) ODP-AGM94R H7 L4. The Odyssey Performance System batteries offer increased reliability and a longer service life compared to a conventional battery.

Manufactured by Oyssey using plates made out of 99.99% pure lead, not less expensive lead-alloy like many competitors. Pure lead allows the plates to be made thinner, so you can fit more plates inside the battery. More plates equals more surface area, which translates into extra power!

In order to produce the highest quality battery available, they are built to stringent specifications. Batteries feature upgraded cell connectors which are casted to the plates, and bonded to resist vibration and eliminate internal sparking making them extremely durable on the road or off. In addition, all batteries employ dry cell Absorbed Glass Mat (AGM) technology to contain the acid, so they can be mounted in almost any position.

Features:
  • Longer Cycle Life
  • Maintenance Free
  • Vibration Resistant
  • Extreme Temperature Tolerance
  • Mounts in Virtually Any Position

Best Ram 2500 battery

Best AGM battery for your diesel, cold cranking amps. I use a battery shutoff to avoid the constant electrical drain.

Odyssey batteries

I been using odyssey batteries for several years and they stand up to severe heat, work, cold, and even long periods of sitting while still using power inside the truck. XDP offers these batteries at a better price then any parts house plus the have lightening quick shipping and no core charges either. I will always buy my batteries from XPD And I recommend everyone so the same.

Not worth the money, barely lasted a year.
Jake (Henderson, NV) | April 13th, 2022
Purchased 2 of these for 08 dodge ram Feb 2021 its been a little over a year now and I'm starting to look for battery's again. Drops to 9v when cranking. Everything else cables, starter, alternator etc. are all new performance parts. I don't know what all the hype is because I'm not impressed.
