No. In fact you should never discharge your lead acid battery below 80% of its rated capacity. Discharging a 12 volt battery below this point, or 10.5 volts, can damage it.

No. If you completely exhaust the battery before recharging it, the cells will deteriorate faster, thus shortening the life of the battery. When the power of the tool becomes weaker, stop using the tool and recharge the battery.

Under standard or normal conditions, you "never" need to add acid or electrolyte (unless tipped over). Low maintenance batteries may need fluid added to keep the "plates" safely immersed. Only distilled, deionized or approved water should be added.

No, "topping-off" the battery is perfectly OK. The lithium ion material used for the Z-Max power module does not develop a "memory" during a partial charging cycle. The battery module should be calibrated (also called conditioned) as part of regular maintenance every 10-15 full charge cycles or about every two weeks. If the battery is not calibrated for a long time, the status LED's may not report correct capacity information.

Yes. All batteries, regardless of their chemistry, will self-discharge even when no load is present. The rate of self-discharge for lead acid batteries depends on the storage, operating temperature and condition of the battery. At a temperature of 80 degrees F, a lead acid battery will self-discharge at a rate of approximately 4% a week. A battery with a 125 amp-hour rating would self-discharge at a rate of approximately five amps per week.

No. Routinely running the lamp until it extinguishes will drastically shorten the life of the battery. Lead acid batteries need to be fully charged. The higher the average charge on the battery, the longer it lasts. Deliberately draining a lead-acid battery will quickly destroy it. See the Retail Price List on this website for replacement batteries. Numbers on the older batteries may not be current. Multiple numbers on the same battery are for regulatory requirements.

Yes, a permanent magnet DC motor used as a pedal power bicycle generator can charge lead acid deep cycle / car batteries through a charge controller as shown in the diagram below. One of the cheaper solutions you can try and use is the Xantrex C35 charge controller. It costs about $107.00 (Click HERE for order information). It can handle 35 Amps. The C40 and C55 are also good options. The Xantrex C35 owner's manual is very explicit on how to setup your battery system. See page 47 of this manual.

Under normal operating conditions, you never need to add acid. Only distilled or de-ionized water should be added to achieve the recommended electrolyte levels.

I have dual zone climate control. Can I make the driver's side temperature knob control both zones? 5. NAV System / Radio Questions

Gel cell or sealed lead acid batteries have basically the same chemistry as wet or flooded cell batteries. The batteries' electrolyte is in a gelatin form and is absorbed into the plates. The battery is then sealed with epoxy. These batteries may be used in any position. They are exceptionally leak resistant. Applications include UPS devices, emergency lights, and wheelchairs. These batteries contain 2 volts per cell with common voltages of 4, 6, and 12 volt.

Our chargers charge and float lead-acid batteries at a different voltage than gel-cell batteries. You should not mix battery types because you are going to compromise a battery if you charge it at the wrong setting.

It is best to fully charge a new NP-400 battery that comes with an Ax before using it. After that, it is better to charge the battery often, especially before use, rather than letting it run down too much, or the battery life may be affected. Don't worry about the Ax losing any of its settings while the battery is out of the camera as the camera can remember the settings for quite a long time. Spare batteries are not a bad idea as you cannot use your Ax without power.

No. The tiny switch on the speed controls is leveraged many thousand times by the FET drive transistors. The switch controls the bias on the FET’s to turn them off completely and current flow to the motor is zero. As indicated in the manual, you may wish to install a switch in the battery line on the SC5 which does not ship with a switch for weight conscious applications. The M-SONIK SPORT ESC does not have a switch and you may choose to put a switch in line for it.

The way the Ultra-Mobile PC is used will determine the actual time before the battery needs to be recharged. The new mobile processors being released increase battery life considerably. Currently, the minimum battery life for an Ultra-Mobile PC is 2.5 hours, although most manufacturers claim 3 hours or more.

There is a DC-to-DC converter that steps the 144-volts from the battery pack down to12 volts for the lead-acid battery (which also provides power for the Insight's 12-volt accessories). Honda's heard this question many times and says no, the engine bay is too small for a larger engine (my solution: tell Honda you want them to resurrect the CRX).

Ni-Cd batteries must be fully discharged every 5 to 10 charges to avoid memory effect. If the battery has not been entirely discharged, the charge will not be complete and will set a new lower energy capacity. This is called the 'memory effect'.

Lead acid Batteries should never be discharged below 20% of the Batteries capacity. This can be determined by a "fuel gauge" mounted on the Truck. Most meters will give you some kind of warning.
