Battery Help

Recommended Posts

My battery was re-located to the boot, I doubth it will last much longer. The car is a lift back so I cannot use a normal Lead (wet) battery due to discharge from wet batteries.

 

Currently I have a red Top Optima (AGM Battery);

 

Optima Part Number: 34R (8003-151)

RedTop®; Battery; UNBOXED; Group 34R; Cold Crank Amps 800; Crank Amps 1000; Reserve Capacity 100; Ampere Hour 50; Top Terminal; L-10 in.; W-6 7/8 in.; H-7 13/16 in

 

Any advise on what to go for, I am reading mixed reviews about Optima batteries, to be honest I dont want to have to shell out 300euro on a new Optima battery and it only last a few months.

I need one I can leave for long periods car only get use weekends and off the road during the winter.

 

Get a deepcycle ? but I just bought the Ctek Trickle charger but I dont want to keep having to take the battery in and out. I want to leave the car idle for min two weeks and still be able to start it

Do you park your car on the street? I have my trickle charger plugged into the car constantly.

 

As already said, yellow top is a good deep cycle battery.

 

I am in an appartment so I cant use my mains trickle charger, but during the winter i will take the battery out. I was thinking of the solar panel trickler charger to do me for the summer, save me taking the battery in/out

Stay away from the red top, I had this on my Supra, When it was left to go flat a few times it was totally dead and had to be bumped every time.

 

As Scott has already said, The yellow top should be better.

 

I was going to go with an odyssey battery, I was recommend the Race xtreme 30 or 40

 

I cant find anywhere over here who sells Optima so getting a replacement (under warranty) might be an issue if I get it from the uk

Odyssey Xtreme Racing Batteries (Good read) -- they dont need a trickle charger for winter storage plus you can leave them in the car over the winter ;)

 

http://www.odysseybattery.com/documents/US-ODY-ER-OM-001_1008_rev.pdf

 

The ODYSSEY® Extreme Racing™ battery does not lose its charged energy during cold storage

temperatures, so there is no need to trickle or float charge during winter months. To store off-season,

measure the battery voltage to make sure it is fully charged, 12.84 volts or greater; recharge if necessary.

Disconnect the negative battery cable to prevent any applied electrical load during storage. The ODYSSEY

Extreme Racing battery cannot freeze down to -40°C (-40°F), so it can be left in the vehicle. It can be

stored for 2 years or more below 77°F.

Most sealed batteries are like that bud. You shouldn't need to take the battery out to charge it if you disconnect it from the negative terminal :)

 

The only reason I had so much bother was due to leaving it connected.

 

Thats the mistake I made, so do you reckon leaving dis-connected in the car in winter temps or bring it in the house

That's a pretty impressive battery if it can be left for months without any charging!

 

2 years it says if it is around 25 degree temp, it talks how the storage life deteriarates with an increase in temp but I wonder if a decrease in temp will affect it too

 

B) How long can the battery be stored?

Refer to Figure 3 below. At 25°C (77ºF), these

batteries can be stored for up to 2 years. The

lower the temperature, the longer the storage time.

The battery must be charged before storage.

Roughly every 10°C (18°F) increase in temperature

cuts storage time in half. If the temperature rises

to 35°C (95°F) the battery may be stored for only 1

year before a recharge becomes necessary. Figure

3 will apply only if the battery is fully charged

before storage.

Most sealed batteries should last years on the shelf without any charging..... as long as they aren't connected.

 

Even the redtops last ages. In fact I had a halfrauds battery in my garage for 5 months (over the very cold winter too) and it still had a perfectly good charge on it when I checked it over for a mate.

 

The main issue is that owners don't disconnect their batteries before leaving them for long periods of time. I never know when I'm going to use my car so I am very guilty of doing just that, hence why I got the trickle charger :)

I use the Halfords HCB005 Calcium battery. Has been great for cold start and when left for long periods of time. :)

 

My battery was re-located to the boot. The car is a lift back so I cannot use a normal Lead (wet) battery due to discharge from wet batteries

Otherwise I would just the the Halfrauds and hide the label ha ha

I don't like seeing people being reeled in by marketing crap though. To be honest you would be fine with a standard battery if you got into the habit of removing the earth connection when you knew the car was going to be sitting for a while.

 

Personally I would go with the yellow top as they are tried and tested. The only reason I went with the redtop was to match the rest of my engine bay :D

Maybe thats why I have one of those circuit breakers you can twist on the earth ha ha

 

Just ofr warranty purposes I will get the odyssey because I can get it local, nobody in Ireland seems to sell Optima

 

Reading around i heard alot of good reviews on forums about odyssey vs Optima
