No. By adding the acid you are activating the battery. After adding the acid, the battery will be charged 80% to 90% within 15 minutes. It can be used immediately, and the system will complete the charging process once the charger is plugged into the wall.

Under normal operating conditions, you never need to add acid. For a standard auto or marine battery, only distilled, deionized or approved water should be added to achieve the recommended levels mentioned above. When a battery is shipped in a dry state or accidental spillage occurs, electrolyte should be added to the battery. Once filled, a battery should only need periodic water addition.(Return to Top)

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 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.

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.

Out of the box, it should be charged non-stop without using the radio for about 16 hours. Keep in mind that it will take about 3 full charge/discharge cycles before the battery pack achieves it full power capacity. In everyday use, you should use the radio and battery continuously until the radio tells you the battery needs recharging. At this point, the battery should be FULLY charged with the radio turned off (about 14 hours).

It depends on the type of charger and the size of the mobile phone battery. A rapid charger will charge a slim battery in as little as 30-45 minutes. A standard charger will take from 8 hours to almost 20 hours for extended batteries. Most in-vehicle chargers will rapid charge the battery to about 50% capacity in less than an hour, then switch to slow charging.

If your work load is very active during the day we recommend Charging every night. If the duty is light, then we recommend charging every other day or even less frequent. Keep in mind that the least amount of charge cycles received by the Battery the longer the life of the Battery.

The approximate number of recordable images is 165 with flash fired for 50% of the shots and LCD monitor on, and the playback time is approximate 160 min. Note: The description above (1) is according as CIPA standard and above (2) is based on PENTAX measuring conditions and may vary depending on factors such as capture mode and shooting conditions. The age of the battery can also affect these statistics.

There are three battery technologies in common use these days. Each of these battery technologies has its own unique properties and its own peculiar charging requirements. Here is a summary of those available technologies: This is the oldest of the three technologies, but you will still find quite a few batteries of this type still around. Cadmium is extremely toxic, and so this type of battery has been slated for extinction in the near future.
