Pros / Cons Single or Twin Battery Mk7

[Rubz]

Afternoon all,

What are the pros and cons of a twin battery over a single?

My mk7 2.2 fwd has a single battery but seen a few people convert to a twin.

Just looking to see if its worth the time/ money / effort of adding a second battery.

cheers all,

Euan

Punto has the stuff you need it's in the sale section.

The main and overall bonus to twin battery setup is that, provided you maintain 2 good batteries you'll never go flat by accident.

Imagine if you went to do a bank raid and you left the lights on that could be embarrassing, especially when you have to explain to the wife and kids that you, Charlie and knuckles are doing a stretch in the klink

The above scenario generally can't happen on twin battery system.

Down side is that when the front battery dies, you have to rely on your Jedi powers to spot it, usually tell tale faults occur tho.

Good set of jump leads left in the back ,scrounge a jump if you ever need it.

And save yourself approx £100 .

If you frequently use things powered from the van with engine off, it's worth it.
If you don't, then it's up to you, but I reckon it's still worth it!

Some folk have been known to leave dash cams plugged in , and even Chinese USB sockets, which can flatten the battery after a few days of not using the van

Having a separate starter battery, isolated from the rest of the system is ideal for such folk, and you have the added bonus of additional starting amps in cold weather

cheers for your thoughts guys. Ive bought the twin battery set up from punto.

for buying a second battery, should I get the exact same one I have currently? or a smaller capacity battery?

[gotgcoalman]

Haven't got a mk 7 but from what iv'e read in the past and what i'd put on
my mk5 is a matched pair.

[Altransit]

Ideally, the same size and capacity, but as they're not connected together when discharging, it's not essential.
I wouldn't use a smaller one than the original, as it may need to start the van on it's own if the other battery is flattened or goes faulty

10-4 roger that i was thinking that would be the anwser.
