You can pick up an H8 battery at your local Sears store. If you decide to buy it at Sears, ask for DieHard Gold AGM battery Group Size EP-49 (which is the exact same battery as your H8 battery). The DieHard Group 49 Battey has a 3-year warranty. At the time of this writing, it was priced for $220 at Sears.com. Check online retailers for a better price.

Listed retail price is $169.99 but with 20% discount coupons often available on the Pep Boys website the battery can be purchased for as low as $135. If you are looking for a reliable battery brand like Bosch, then Pep Boys is where you need to go. At the moment they seem to be the only major retail carrying Bosch batteries.

Excide makes some of the best H8 batteries. Excide batteries can be hard to find, but we have been able to spot Exide batteries at local Home Depot stores. Exide L5/49 is the equivalent of the H8 battery. Exide makes two H8 (or as Exide calls them L5/49/H8) batteries. The Excide Edge which is an AGM battery and the Exide Extreme which is a lead-acid battery. The Exide Extreme is worth considering. It has the best specs of any H8 battery in this list and at the time of this listing was listed at only $119. Note the stock picture on Home Depot product listing page. The H8 battery picture is incorrect and does not represent an H8 battery.
Super Start Group Size 49 Battery
Super Start Group Size 49 Battery
Cold Cranking Amps (CCA): 850 A
Cranking Amps (CA): 975 CA
Reserve Capacity: 170 min
Type: AGM
At O'Reilly stores, you will find Super Start Platinum Group Size 49 Battery. The Super Start brand is not really a recognizable brand when it comes to the world of batteries. A plus for the O'Reilly's H8 battery is that this is an AGM battery. The downside is that it is priced at $190 and comes with a 3-year limited warranty. Ignoring the lack of brand history but only considering the price and warranty terms, this may not be the best H8 battery you can buy.

Battery Buying Tips
When buying an H8 (Group size 49) battery there are three parameters that are very important to consider:
- Cold Cranking Amps (CCA) measured in Ampere
- Cranking Amps (CA) measured in Ampere
- Reserve Capacity (RC) measured in minutes.
Because luxury cars put a high demand on the battery especially when the car is not running, consider buying an H8 battery with the same or higher Reserve Capacity (RC) rating than the original.
It is important to take into consideration the battery type as well (Lead Acid vs AGM).
