It is very important condition (fully discharge after which fully charge) the battery every two to a few weeks. Failure to take action may significantly shorten the battery’s life (this doesn’t apply to Li-ion Battery, which don’t require conditioning). To discharge, simply run your device under the battery’s power until it shuts down or until you get a low battery warning. Then recharge the battery as instructed for your user’s manual.

  Emergency lighting power tool batteries are divided into two categories: nickel-cadmium batteries and sealed lead-acid (SLA) batteries. The latter is technically comparable to car batteries. The major difference between the 2 is the kind of substance that’s used for triggering a chemical reaction. Comparison of those two forms of electrical charging batteries takes cost, size, life, and sturdiness under consideration. The lead-acid kind of battery is generally used for emergency lights with steel enclosure.

It is acceptable for applications where the emergency lights are used for short periods. Although they’re more proof against heat and cold than the nickel-cadmium batteries, these batteries are bigger and heavier. SLA batteries are best if you find yourself considering power storage which have a low-cost. Another benefit of these MAKITA batteries is that they only have 5% discharge rate per 30 days. If consumers are seeking for portability, Nickel-cadmium batteries have a much bigger advantage. It’s lighter, smaller and provides longer battery life. The down side to those batteries is its cost and wish for periodic discharge.

  The very first thing that customers want to know is the battery capacity. a bigger battery doesn’t automatically mean that it’s going to last more than its smaller counterpart. Check the ampere-hours printed inside the battery casing. This translates to the electric energy that a battery can store.

  Another thing to contemplate is battery voltage. Emergency charging batteries could have voltages starting from 6 -24 volts. Generally, brighter lamps mean higher voltage. If the batteries need replacement, be sure you buy similar battery types and battery voltage. Otherwise, you’ll likely encounter charging problems. 

  Proper care of emergency lighting batteries can be a major assist in prolonging its service life. Making sure that the batteries have longer life, ensure that charging time is monitored. When batteries are charged or discharged hastily, the chemical efficiency of the device is affected. This can also heat up quickly the batteries, thereby causing an indirect effect to its efficiency.  The similar thing may also happen whether it is charged slowly. SLA batteries typically desire a charging time of no less than 5 hours.

Actual battery run-time depends on the facility demands made by the equipment. In terms of notebook computers, using the monitor, the harddrive and other peripherals leads to a further drain upon the HITACHI battery, effectively reduces the battery’s run-time. The whole run-time of the battery could also be heavily dependent upon the design of the equipment. To make sure maximum performance of the Laptop Battery, optimize your computer’s power management features. Confer with your computer manual for further instructions.
