A Sealed Lead Acid (SLA) battery, also known as a VRLA, Valve Regulated Lead Acid battery, has the following attributes: maintenance-free, leak-proof, and not sensitive to positioning. SLA batteries are equipped with a safety vent to release gas in the event of too much internal pressure.
SLA batteries are used in many applications, such as home alarm systems, backup systems, generators, flashlights, spotlights, workout equipment, generators, motorcycles, ATVS, toys, and much more.
Ah stands for Amp Hour, a technical term for how much energy a battery will store. Batteries with higher Ah values are able to last longer between charges. The higher the number, the more energy a battery can store.
In some cases, where physical dimensions allow it, you can upgrade to a higher Amperage battery. For example, a device using a 12V 7.2Ah can use a 12V 9Ah for longer run time. Any bigger and the battery will physically not fit into the device, as the physical dimensions will be different.
The voltage of the original and the replacement has to be the same. In our example, a 12V 7.2Ah can be replaced by a 12V 9Ah for longer run time, but the battery must be 12V.
SLA batteries naturally discharge over time. If it is not charged periodically, the battery’s full capacity may not be reached again. SLA batteries self-discharge at a rate of around 3% a month. UPS Battery Center recommends checking on and charging SLA batteries every three months.
Never store an SLA battery longer than six months without recharging it. Always store batteries in a cool, dry place. Generally, a battery can last 6 months to 1 year on a shelf at 25 degrees celcius.
To be kept on a charge continuously a
"float" charge is needed. A float charger will deliver a lower
voltage charge (2-v range) consistently and will can help keep a SLA battery in
good working condition for long periods of time.
At a full 12-14v charge, the
charger needs to be removed as soon as the battery is charged or the plates can
become corroded and a battery can be ruined in days or weeks. Unregulated
Transformer-Based Chargers, should be removed right
away after a full charge is achieved.
For a float charge a more sophisticated
charger is needed. If a unit is being unused for an extended period of time it
should be stored in a cool place with a float charge on it. Otherwise the
charge of the battery should be constantly monitored, making sure it is never
fully discharged, and charged periodically with the charger being removed as
soon as a full charge is reached.
Do not use an automotive battery charged to charge small sealed lead acid batteries. Car battery chargers are designed to work with big SLI batteries and charge at a high amperage. For small batteries like 6V 5Ah or 12V 9Ah this will be too much amperage.
Although it will charge the battery, it will significantly reduce the life time of the battery and will likely cause permanent damage to the battery.
To charge small sealed lead acid batteries, buy a sealed lead acid battery charger that charges small SLA batteries at approximately 1A. A trickle charger is perfect for sealed lead acid batteries, it a slow charger but will ensure a long life time for your battery.
There's absolutely no problem using a 12V 5Ah battery in the alarm system. There will be no damage of any kind to the alarm system. The slightly higher amperate will result in a longer up time for the alarm when the power fails.
If maintained properly a sealed lead acid
battery will last up to 5 years. However just one extended discharge can render
an SLA battery useless. Even a near deep discharge can greatly reduce the
amount of charge a battery will ever be able to retain. An SLA should never be
fully discharged, as the battery does not need to be periodically discharged in
order to maintain its performance, in fact, it is best kept in a fully charged
state at all times. SLA batteries can also be damaged by overcharging. A
charger should be removed as soon as the battery has reached its full charge.
They should be stored in a cool place when not in use, and can be damaged if
stored in a hot area for an extended period of time.
Immediately remove the swollen battery from the equipment it is in. A battery expands due to overcharging. High rates of overcharging will cause a battery to heat up. It accepts more current as it heats up, heating it up even more. This cycle of overheating is called thermal runway and it is able to destroy a battery fairly quickly, sometimes in only a few hours. Heat that causes the battery to swell.
The battery is not usable. Recycle it a local battery recycling facility. This battery needs to be replaced immediately.
A gel cell or gelled electrolyte is a sealed battery containing semi-solid electrolyte and may also be identified as a sealed lead acid, AGM(absorbed glass mat) or VRLA type battery. AGM batteries are sometimes referred to as starved electrolyte because the fiberglass mat contained within the cell is saturated only 95% with acid and there is no excess liquid. Nearly all AGM batteries are VRLA or valve regulated. VRLA batteries are designed with a valve that allows the battery to keep a slight positive pressure.
It is best for all types of lead acid batteries to be maintained in a fully charged condition. If you have not done this, you should charge your battery at a minimum every 30 days. You might consider getting a smart charger to maintain your battery all the time.
You can connect your SLA battery in series or parallel. Connecting your SLA batteries in series will generate a higher voltage. For example, connecting two 12 Volt 18Ah batteries will give you an output of 24 Volts with capacity 18Ah. Connecting your SLA batteries in parallel will generate a higher capacity. For example, connecting two 12 Volt 18Ah batteries will give you an output of 12 Volts with capacity 36Ah.
Call the manufacturer of the unit or check it in the manual. Confirm that your device has a removable battery. Find your device model number. Then search it on our website, you'll need to enter your device's information, like the model number or the manufacturer part number.
Determine the purchase date of the cell phone or the installation date of the battery. Cell phone batteries only last between one to two years, which equates to approximately 300 to 500 charging cycles. If the phone battery is older than two years, it should be replaced.
New Laptop Battery Calibration. If your new battery charges but does not charge to 100% or stops charging each time your charge indicator reaches 85-99%, you may need to recalibrate your laptop for the new battery. This occurs often when replacing an old battery with a new battery. The laptop has to adjust itself to get used to the new battery. In order to recalibrate properly, you will need to set the Windows power management so the laptop does not go into standby or hibernation when the battery gets low. Instructions: With Windows XP, navigate to Control Panel > Performance and Maintenance > Power Options. Set "Power Schemes" to "Always On". Under "Alarms", uncheck "Low battery alarm" and "Critical battery alarm". Under "Hibernate", uncheck "Enable hibernation", then click on Apply. With Windows Vista, navigate to Control Panel > Performance and Maintenance > Power Options Click "Change Plan Settings". Set all tabs to "Never" underneath "On Battery" column. Click "Change advanced power settings". Set Sleep > Hibernate after to 0 or Never. Set Battery > Critical Battery Level to 0. Click on "OK", then "Save Changes". This is the only time that we recommend taking the battery all the way down to zero percent. Unplug the ac adapter, and let the battery drain all the way down until the laptop shuts off. Then plug the AC adapter back in, and let it recharge to 100%. You may need to repeat the cycle 2-3 times before it actually reaches 100%.
mAh stands for Milliamp Hour, a technical term for how much energy a battery will store. Batteries with higher mAh values are able to last longer between charges. The higher the number, the more energy a battery can store.
It depends on the battery and charger. Some batteries take 10 to 24 hours to charge, but most will recharge in 1 to 2 hours. For more information on your battery-charging requirements, refer to your cell phone or battery-charger manual, or contact the manufacturer.
Leaving your phone plugged in when it's fully charged, like you might overnight, is bad for the battery in the long run. Once your smartphone has reached 100 percent charge, it gets 'trickle charges' to keep it at 100 percent while plugged
