For Quality New & Reconditioned Batteries

FAQ

Q. What do you mean by cap vented and sealed maintenance free batteries.

A. A MF or a maintenance free battery has inbuilt recondensing valves and chambers in each cell which ensure that no moisture is lost, hence no checking or filling up of the fluid levels is required. A cap vented version has six caps on top of the battery that need regular checking and topping up if required.

 

Q. What is a calcium modified or a double calcium battery really mean.

A. The lead and or the lead oxide layer on the grid plates is alloyed with calcium. A single calcium battery has only the lead oxide or spongy layer alloyed, whereas a double calcium battery has the lead grid plate alloyed as well.

 

Q. What is the advantage in calcium alloyed batteries.

A. The lead oxide and lead layers when alloyed with calcium adhere much better to the grid plates, and are much less likely to fall off into the bottom of the battery. Double Calcium batteries self discharge at only 3% per month as compared with nearly 1% per day with conventional batteries.

 

Q. Do I need any special or different charging systems for Calcium batteries.

A. Simple answer NO. All batteries respond better to a trickle charge as apposed to a high burst and Calcium batteries are no different.

 

Q. What do you mean by recondition.?

A. The reconditioning as referred to with Nulife Batteries is a chemical process that dissolved the undesirable sulphate. The Acid is not taken out, may be strength adjusted, & the battery is then fully recharged & load tested. By redissolving the lead sulphate back into solution, the chemical balance is returned.....it is as simple as that!

 

 Q. Can you treat so called “sealed batteries” with this method.

A. Yes we can, the term sealed can be a little misleading as even so called sealed batteries have two small "breathing" holes.

 

Q. What sort of life expectancy can I expect out of my Nulife reconditioned battery.

A. You can expect up to at least 18 to 24 months under normal conditions. We have seen them last longer though.

 

Q. What is sulphation and why does it occur?

A. The buildup of lead sulphate is the natural chemical process that occurs when the battery discharges. It is normally dissolved in the recharging process, but if the battery is left in a discharged or semi discharged state for too long, this sulphate buildup becomes excessive and changes in its crystalline shape, making normal recharging systems unable to re dissolve it.

 

Q. I had a new battery that I hardly used and over a 12 month period sitting on my garage floor it went completely flat and had to be replaced. Is this normal?

A. I am afraid it is. All batteries will slowly discharge themselves over a 3 month period, with the slow buildup of sulphate occurring. If allowed to fully discharge and stay in that state for a long period of time, the sulphate will change in structure so as to make normal re charging impossible. Storing it on a cold concrete floor doesn’t help either!

 

Q. How does your company operate?

A. Nu Life Batteries collects old battery shells from businesses that use or sell batteries, and from private individuals. They are initially tested and the “able to be reconditioned” units are then processed. We primarily sell direct to the public. We also sell direct via our website.

 Q. Where can I buy one from?

A. There is a list of wholesalers on the site, or you can contact me direct on sales@nulifebatteries.co.nz

 

 Q. Is there a difference between a recharged battery and a Nulife reconditioned battery?

A. There surely is, a battery that has some sulphate buildup means that its active surfaces have decreased and as a result has less surface area to hold a recharge. A Nulife treated unit removes all of the sulphate and the original surface area is again available to accept and store a charge.

 

Q. Are all lead acid batteries able to be reconditioned?

A. Unfortunately the answer to that question is “No” Batteries can fail for other mechanical reasons such as bent & dislodged plates and they cannot be refurbished. Experience has shown that close on 60% of the batteries can be chemically reconditioned, and if the worlds total use was recycled to that extent, then our landfill would be greatly reduced.

 

Q. Is there any special tips on looking after my battery so as I can maximize its life?

A. Without a doubt the golden rules are all about caring for your battery are all about not letting it get too discharged, recharging it as soon as possible. Heavy draw downs and high recharging rates do not help either. For batteries that get intermittent use such as in boats and motor-homes it pays to have a low amperage floating or automatic charger on them between uses. These compensate for the gradual loss of charge and do not overcharge when the battery is fully charged.
