SERVICE & SUPPORT

We design it, We build it, We test it for quality, We ship it with confidence.

Unlike many disposable products on the market today all of our products are designed for industrial duty use and are "non-landfill compatible."  We still get a kick seeing our products reliably doing their job for 10 years or more. If you have any of our products that are not working, we would much rather repair it than sell you a new one. It's almost always cost effective to do so, and we can both help put a little less stress on the environment in the process. Thanks for your cooperation.

So should your charger or accessory need service, it can be returned to us, or sometimes trouble shooting and repair can be done over the phone, or by E-mail. If you think this is possible, you may call or E-mail us. If the charger is under warranty, we may choose to send parts to be installed by a qualified technician. There will be no charge for the parts. Quick Charge Corp. is not responsible for labor charges.

If field servicing is not possible, the item may be returned to us. Please print out this PDF RMA form, and fill it out. Pack the item, with the form carefully in a box suitable, and strong enough to avoid damage. Quick Charge is not responsible for damage caused by insufficient packing. Send the package freight prepaid by the carrier of your choice. Once received, we will get the item repaired ASAP, usually within a couple of days to 1 week. If the item is under warranty, we will pay for the cost of repair, and the return freight. If the item is out of warranty, we will contact you with repair charges, you will also be responsible for return freight cost. A credit card will be needed for those customers not having an open account with Quick Charge. 

Call us at 800 658-2841 Monday - Friday, and try us on Saturdays, we are in and out.

E-mail us at quickcharge@icnet.net Most of the time we will get back to you within a few hours, weekends included.

FAQ

How do I size a charger to my batteries?

With lead acid batteries you usually use the 10% rule. That is, the charger rating should be about 10% of the amp hour capacity @ the 20 hour rate, so if your batteries are rated at 250 amp hour you would select a 25 amp charger. This is not a hard and fast rule, and you can stray from it with the understanding that the farther you stray, the less life and or performance you will receive from your batteries.

My On Board charger get's so hot I can't keep my hand on it, is this normal?

Yes, the On Boards are not ventilated so all the heat generated is dissipated through out the aluminum housings that are a heatsink. A temperature of 160-180F is not uncommon.

I put a volt meter across the charger output leads and nothing comes out. Is something wrong?

No. All of our chargers require some battery voltage across the leads to turn on, so if your battery is stone dead, the charger will not come on. If yours is an On Board with a single green LED then approximately half the chargers rated voltage will be required to turn it on. If yours is a portable or stationary with a dial face ammeter, then the same is required. All other models have a much lower turn on threshold. If your batteries are in a series string, get some voltage into the batteries by charging them individually. (you don't need to disconnect all the batteries)

I'm switching to a lithium ion pack. Will my charger work as is?

Maybe, but probably not. Much depends on the number of cells, and the desired charge to voltage. It is best to contact us. Some models will not work at all, and some may be re-calibrated to work. Generally, once the charger is calibrated for Lithium ion, you won't be able to go back and use it on lead acid with any level of precision.

How long will it take to charge my battery(s)?

The answer varies widely. Factors include:

Size of charger to battery, temperature, age of battery, depth of discharge, and chemistry. A deep- cycle battery will take longer than a starting battery. If you use the 10% rule as described above, and figure the battery is completely dead, count on 8-10 hours, with the time increasing with the increase in battery size. In other words, a 10 amp charger on a 100-120 amp hour battery will take the 8-10 hours, but if you put a 60 amp charger on a 600 amp forklift battery, it will take around 16 - 18 hours, so it's okay to bend the 10% rule in favor of a larger charger as battery size increases.

How often should I charge my deep cycle batteries?

This is another answer with widely variable factors and opinions. Generally, on a deep cycle set, the deeper you discharge, the fewer the cycles. A deep discharge would be considered around 1.95 open circuit volts per cell in our opinion. Some consider discharging more than 50% to be excessive. Shallow discharges result in more cycles, but can reduce capacity due to sulfation. The user must weigh the cost of deeper discharges, and more frequent battery replacement against longer life, and limited usefulness, whether that's the range of their electric vehicle, or run time on their floor scrubber.

Firm statements we feel comfortable making are:

When possible, plug your charger in after any discharging this is referred to as opportunity charging.

Do not leave your batteries in a deep discharged state. Recharge immediately, but not if the batteries are warm. Allow a cool down time.

If your not going to use your batteries for extended periods, leave the charger plugged in and let it float/maintain. Lead acids self discharge, and in some cases you can return to find your equipment disabled, and your batteries ruined.

Do I need temperature compensation on my charger?

First, what is it? The voltage that batteries should be charged to depends on the ambient temperature the batteries are exposed to. Colder temperatures require a higher charge to voltage, while hotter temps require it to be lower. Too high a voltage at high temps will result in over charging/water usage. Too low a voltage in cold temps may result in undercharging, so it depends on your application. Two examples would be, If your charging batteries in a warehouse for your pallet jack, no. If your float charging batteries for a standby generator which is exposed to wide temperature swings, yes. This feature is standard on our strictly float type chargers (OBE) we offer it as an option on everything else. It should be noted that for temp comp to be useful, the charger must measure the ambient air temperature that the batteries are exposed to, this means the probe must be out of the case, and not influenced by heat generated by the charger.
