Power Tanks in Aldi

The 70Ah one on your link is 193 (for one), and what would the shipping be ??
The 110Ah battery in Halfords is 200e ! the 7e more packs you alot more power.
These beasts are mad expensive.!

€4.40 is the delivery charge, it's seems to be their standard charge for delivery, no matter what the weight is,

I'm impressed, they havent weighed these I'd bet :lol:

I just found the below elsewhere on the web, good to know......


LEISURE/DEEP-CYCLE BATTERIES

A word of advice!

Take care to calculate all your 12 volt items and their requirements before the initial purchase as a lightly used battery will eventually be the most economic.

Leisure batteries are designed to give a steady low amp discharge rather than meet the sudden demand required from a car battery to start an engine.

The life of a leisure battery is largely determined by the depth of the discharge cycle. We will say as an example that a leisure battery that is discharged each time by 15% of it's capacity may last for ten years. The same battery discharged by 30% of it's capacity will last for 8 years, 50% for 5 years, 75% for 3 years and possibly being discharged by 100% lasting only 1 year.

A 100 amp hour battery delivers 100 amps for 1 hour. Or 10 amps for 10 hours etc in theory, but in reality you should never drain the battery that much.

Power is amp x volts, so 100amps at 12v = 1200 watts, or 1,2kW 1.2kW for 1 hour is 1.2kWh.

Any form of heating element will cause a rapid drain on a battery, an electric kettle for example, also remember that a non compressor type refridgerator relies on a heating element to function.

All batteries self discharge when not in use and leisure batteries will self discharge 7 to 10% monthly.

How to kill your battery dead!

1/. Uncontrolled Charging causes overheating and gassing.

2/. Used too little (memory effects, so cycle every 2 months)

3/. Stored discharged (sulphating, any flat battery left flat will be scrap within 3 months)

4/. Do not store on a cold surface as this rapidly increases the self discharge rate.

5/. Too much deep cycling (a good rule of thumb is not to go beyond 50% of the battery's endurance at worst)

Volts - State of charge
12.7V or over – 100%
12.5V – 75%
12.4V – 50%
12.2V – 25%
12V or under – Discharged

When battery manufacturers state that a battery has a capacity of 110 Ah they presume the battery will be operating where the ambient temperature is 25 degrees centigrade. For every 1 degree centigrade drop in temperature the battery capacity falls by 1%

The time required to recharge a leisure battery can be calculated as follows. The recharge time in hours equals the battery capacity in Ah, multiplied by the Depth of Discharge in %, multiplied by 0.8, multiplied by 1.5, divided by 100 times the charger current rating in Amps, plus one hour. For example, a 110 Ah battery, discharged to 50%, on a 10 Amp charger, would take about 7.6 Hours

Handy breakdown of power requirements there Dave.
