Need a new battery

[Quik LS]

This may be an option for us - > http://www.odysseybatteries.com/battery/pc1500.htm

I measured my LS battery - OE tad longer and wider - so this should fit.

I have no direct experience with this - but several shops use them for heavy audio/video installs - and like the ads - the batteries can be install right next to the passengers.....

Odyssey combines in one box the characteristics of two batteries. It can deep cycle as well as provide serious cranking power. These batteries are capable of providing engine cranking pulses of 1700a for 5 sec as well as 400 charge/discharge cycles to 100% depth of discharge (DOD). A typical battery can do one or the other, but not both. With other batteries such as Optima, you must decide between a deep cycle or a high power starting battery, but Odyssey does both.

The cranking power of a Odyssey battery is double to triple that of equally sized conventional batteries, even at low temperatures.
Also with simple constant voltage charging, there is no limitation on the inrush current. This means you can charge your battery with as many amps as your charger, alternator, stator, or generator can put out as long as it doesn't exceed 15 volts. Lead acid, gel cell, and other AGM batteries can only accept 10amps per hour during charge.

The ODYSSEY® Drycell battery combines in one box the characteristics of two separate batteries. It can deep cycle as well as provide enormous cranking power.

These dry cell batteries are capable of providing engine cranking pulses in excess of 2150A for 5 seconds as well as 400 charge/discharge cycles to 100% depth of discharge (DOD). A typical starting, lighting and ignition (SLI) battery can do one or the other, but not both. Conventional batteries are either a sprinter or a long distance runner; An ODYSSEY® battery will do both — provide short duration high amperage pulse or low rate long duration drains.

about $188......

Just bought a battery from the dealer today, $99.95, and it's vented, stock 650mA. They said they don't carry the 750s.

Just a question for you experienced guys- I've never changed a vented battery before, just want to make sure I do it correctly.

1) Unplug negative lead first?
2) Unplug positive.
3) Is there a ground wire anywhere?
4) Just slide the black soft rubber vent tube off?
5) reconnect with positive wire first?
6) reconnect vent tube?

Thanks a lot in advance. The most car work I've ever done is topping off my motor oil, so this is a complex project by comparison.

the neg terminal is your ground - so there is nothing seperate.

use a 8mm socket to remove the bolt holding the 'hold-down' bar acroos the battery.

you have the rest of it.

thank you quikls!

One more question quik. Is it safe to disconnect the negative terminal first? I was under the impression that the ground should be disconnected last?

 

[beaups]

I always pull ground first. that way if i hit anything w/the wrench while pulling the pos terminal nothing is live (except for the terminal itself)

I believe so.

The LS uses (primarily) negative switched circuits, meaning most of the circuits are turned on by the PCM (or switch) completing the path to ground. This is why a lot of the installers have fits with the car - tracing voltage can be difficult.

I have a 'master cut-off' power switch install in my LS - and it simply breaks the connection between the negative battery post and the body ground. I have used it for years - no problems.
