Replacement for WKA12-5F - 12 volt 5 ah battery

• 12v 5 AH
• Deep cycle
• Non Spillable Lead Acid AGM

I saw this same battery (different brand) at Batteries Plus for almost twice the price so I ordered it on line and got it fast and fresh. What a nice surprise to me to be able to ship such a heavy item and still beat the local price.

DID NOT WORK!

This item is lowest grade and unreliable. I have installed it as a backup for an alarm system and

it worked for merely 10 days. Then the alarm system beeped to indicate a low battery status again.

For comparison: My old battery (same specifications, 12V, 5Ah) worked for 5 years.

Should this new item be really exhausted after 10 days without ever being loaded once ?

We never lost AC power in these days, so how can a new battery be exhaused so quickly?

Since I could not believe it, I first blamed the electronics for a false battery alarm and cleared

the battery status several times by disconnecting the AC transformer (according to the advise of experts).

With this correct installation procedure, the battery indication went off, but only for 10 days first

and then only minutes thereafter until the alarm system always indicated a low battery status over and over again

with annoying beeping.

Consequently, the battery voltage must drop below the required

level (~11.7V) after a short time, while the AC is actually powering the whole system.

There is always a tiny minimal load, i.e. for the control unit in the house.

In fact, I used my digital multimeter to check the battery voltage under full load to the alarm system (disconnecting the AC manually).

It dropped below 11V after seconds! This is below the required DC voltage to power the system.

If it is not loaded (AC transfomer powered) it shows 13.6V, but only for a short time and then the voltage

declines until the electronis indicate the low battery status. I even measured a steady voltage drop

with the battery de-installed just connecting the two leads of my Multimeter to it.

There should not be a voltage decline measuable with such a high-ohmic load.

This means the battery dischages even with the tiniest load.

This "new" battery actually exhausts after 10 days of unloaded use.

Wow! This is a welcome to burglars!

At least my alarm system is not malfunctioning.

Meanwhile I have ordered a battery from a different vendor to secure our house.

This seller did not respond to my complaint after a couple of days and I am filing a claim to get a refund.

A total disappointment so far.

Used to replace the previous battery in an alarm system. After 10 days, the system started beeping again. The alarm system says it has lost power. If the battery was working properly, it would have power. Waste of money.

I put the battery in and it worked right away. He is still working fine several months later, I would order Zeus again.
