As UPS VRLA battery, the battery is in condition of float charge, but complicate energy shift still run inside battery. The electric energy during float charge has changed to heat energy, so request the battery work environment must have good heat release capacity or airconditioner.   VRLA battery should install in clean, cool, ventilated and dry place, avoid to affect by sun, overheat or r...

Regarding VRLA batteries, Below important maintenance tips to your client or end user, because only regular maintenance can help find individual abnormal battery during use and management system problem, in order to adjust in time to ensure equipments run continuously and safely, also extend battery life: Daily maintenance: 1. Ensure battery surface dry and clean. 2. Ensure ba...

You may have heard it said "you need a 3 stage charger". We've said it, and we'll say it again. The best kind of charger to use on your battery is a 3 stage charger. They are also called "smart chargers" or "micro processor controlled chargers". Basically, these types of chargers are safe, easy to use, and will not overcharge your battery. Almost all of the ch...

Q: How to keep the consistency of the battery pack? A: Though there is a strict battery selection procedure, after a certain period usage, the non-homogeneity will appear more and more obviously. Meanwhile, charging equipment can’t choose and recongnize the weak battery out, so it is user who can take control of how to keep the equilibrium of battery capacity. User w...

Q: What is the storage life of VRLA battery ? A: All sealed lead acid batteries self-discharge. If the capacity loss due to self-discharge is not compensated for by recharging, the battery capacity may become unrecoverable. Temperature also plays a role in determining the shelf life of a battery. Batteries are best stored at 20℃. When batteries are stored in areas where the ambient...

Q: What is discharge efficiency? A: Discharge efficiency refers to the ratio of actual power to nominal capacity when battery discharges at the ending voltage in certain discharge conditions. It is mainly affected by factors such as discharge rate, environmental temperature, internal resistance. Generally, the higher the rate of discharge is, the lower the discharge efficiency...

Q: Does over-discharging damage batteries? A: Over-discharging is a problem which originates from insufficient battery capacity causing the batteries to be overworked. Discharges deeper than 50% (in reality well below 12.0 Volts or 1.200 Specific Gravity) significantly shorten the Cycle Life of a battery without increasing the usable depth of cycle. Infrequent or inadequate recharging can als...

Q: What does the Reserve Capacity rating mean and how does it apply to cycle? A: Reserve capacity is the number of minutes a battery can maintain a useful voltage under a 25 ampere discharge. The higher the minute rating, the greater the battery's ability to run lights, pumps, inverters, and electronics for a longer period before recharging is necessary. The 25 Amp. Reserv...

Q: What is battery rating? A: The most common battery rating is the AMP-HOUR RATING. This is a unit of measurement for battery capacity, obtained by multiplying a current flow in amperes by the time in hours of discharge. (Example: A battery which delivers 5 amperes for 20 hours delivers 5 amperes times 20 hours, or 100 ampere-hours.) Manufacturers use different discha...

Q: What are the advantages and disadvantages of lead-acid battery? A: Advantages: low price, the price of lead acid batteries is just 1/4~1/6 of that other types of batteries with a lower investment which most users could bear. Disadvantages: heavy and bulk, low specific energy, strict on charging and discharging.  

Q: What is a AGM battery? A: The newer type of sealed non-spillable maintenance free valve regulated battery uses "Absorbed Glass Mats", or AGM separators between the plates. This is a very fine fiber Boron-Silicate glass mat. These type of batteries have all the advantages of gelled, but can take much more abuse. These are also called "starved electrolyte. Just...

Q: What is a Gel battery? A: A gel battery design is typically a modification of the standard lead acid automotive or marine battery. A gelling agent is added to the electrolyte to reduce movement inside the battery case. Many gel batteries also use one way valves in place of open vents, this helps the normal internal gasses to recombine back into water in the battery, reducin...

Q: What determines the life of VRLA battery? A: Sealed lead acid battery life is determined by many factors. These include temperature, depth and rate of discharge, and the number of charges and discharges(called cycles). What is the difference between float and cycle applications? A float application requires the battery to be on constant charge with an occasional discharge. Cycle ap...
