Battery For Charging

[skippy]

Found a nice battery from Interstate Batteries. Will charge both sets of batteries about 5-8 times depending on discharge state.
Part No.SRM-4D about $159.00

Now to find a way to fit it under the hood so you don't have to carry it around :D That's a monster battery.

I have one of those in my boat (http://boatproject.rkedwards.com/). Even in my boat it's total overkill. I can sit at anchor running all my appliances (fridge etc) at full duty cycle for 48 hours without even worrying about it.

With this battery, you need to keep an eye on the fluid level. You will be doing deep discharging and then a killer re-charge. The battery will vent some of its fluid as gases (flamable ones, no less) during a high-power re-charge. Just keep it topped off with distilled water (don't add more acid) every month or so.

What are you using to charge this monster? A Triton? (just kidding) You will likely want a 20amp 3-stage charger or more. If your charger is the type with Bulk-Absorbtion-Float modes (3-stage), don't be afraid to leave it on the charger all the time... But check the fluid level.

Hi Guys,

The battery weights 119lb and has a reserve capacity of 390 minutes @`25 amps. This would translate to about 6-8 charges. If you take the following formula it will help in picking out a battery. 390min/60=6.5 hrs, our charge will average about 22 amps. Now take 25/22=1.136, 390*1.136=443rc, this is the approx new reserve capacity. 443/60*.85=6.2 charges.

Mark,
As far a charging there are many types. My charger is a 3 step process. First 75amp, float 10amp, then maintain. Yes this will vent explosive gases into the air (hydrogen), just charge in ventilated area.

that looks awesome!!! I have vowed not to buy a generator!!!! So you're saying that bad boy will charge both packs 6-8 times??? Do they have a slightly smaller one that will charge like 4 sets of packs off a charge? I don't wanna get a hernia packing that sucker around:-)

THanks for the info, looks like a great alternative to a generator...

That’s why I bought this particular battery to replace a generator. One of the big advantages is no gas or harmful emissions. Yes, it does weight a few pounds and may require hand cart. I sill carry it myself, good exercise. I will look into some of the other batteries they carry and see if I can find one that meets your requirements.

This is what i did to help for my charging. installed a 170 amp alternator and two OPTIMA deep cycle bats. Needed somthin to keep from killin the truck bat all the time :) Of course the TV, VCR, DVD, X BOX, amp for the two 10 in subs and all didnt help :wink: . Not very portable but the heli fits under the hood prety good for charging . Keeps it in the shade too. :) there is a pic of it in my gallery . The two OPTIMAs look pretty cool too :cool:

There is a battery size called 'Group 31' that might work for you, Mike. It's about 60lbs. and is rated at 1190... vs. the '4D' size (seen above) that is 119lbs. rated at 1645.
