OPTIMA Battery for a 2003 Toyota Tundra?
We print our e-mail address (firstname.lastname@example.org) and 800 number (888-8-OPTIMA) on every battery we sell, but some folks prefer to have their questions answered here, on the OPTIMA® Power Source blog. Today's question comes from Matt, who has a 2003 Toyota Tundra.
I have a 2003 Toyota Tundra that doesn't get driven very much. I drive it about once or twice every two weeks and have a hard time keeping regular batteries more than a year (dead cell every time). So would I need a REDTOP® or YELLOWTOP®?
Since Matt didn't give us much more information on his truck, we should mention that a stock truck will work just fine with a REDTOP OPTIMA battery and the 2003 Tundra has a couple of choices, either the Group 34R or the Group 35.
Vehicles that have significant electrical modifications, like aftermarket stereos, car alarms or winches, should use YELLOWTOP batteries and the 2003 Toyota Tundra can accommodate either a D35 or a much larger D27F. However, given how little the truck is used, Matt might be best-served by using a quality battery maintenance device, like the OPTIMA Digital 400, when not using his Tundra. It's possible that the parasitic draw in his Tundra could be slowly discharging his batteries and the charger he is using to try and recover them does not recognize or charge batteries discharged below a minimum voltage level (usually around 10.5 volts). The OPTIMA Digital 400 Charger and Maintainer will recover deeply-discharged batteries all the way back from 1.25 volts!
