It's not going to handle deep-cycle abuse like a lithium pack would, but for backup power in a UPS or an alarm panel where it's mostly sitting on float charge, this is actually a solid choice for the price.
The 4Ah capacity at teh 20-hour rate means you're getting about 200mA continuous draw before votage starts to sag noticeably, and the internal resisance is roughly 34mΩ when fully charged at 25°C — which is decent for a sealed lead-acid in this size class.
We usually have stock on these, but confirm lead time if you need more than 50 units or so, and the ABS case is standerd, not the fire-retardant grade, so don't spec it for anything near high heat or open flames.
What it does is hold a charge pretty well when left alone — less than 3% self-discharge per month at 25°C — and the charge voltage for float use is 13.6-13.8V, cycle use 14.4-15.0V, so you'll need a compatible charger, basically.
The plates are 99.99% pure lead with a Pb-Ca-Sn alloy grid, which is better than the typical recycled lead you see in cheap import batteries, and the design life is 3-5 years depending on how often you cycle it and the ambient temperture.
We typically require a minimum order of 500 units for this model, but we can discuss smaller trial orders if you're just getting started.
Lead time is usually 15-20 working days after order confirmation and deposit, depending on current production volume.
Yes, we include copies of our CE, IEC, and ISO certifications with every order, and we can also provide a specific test report for the batch upon request.
You can store it for up to 6 months at 25°C without recharging, thanks to the self-discharge rate under 3% per month. Keep it in a cool, dry place between -20°C and 50°C.
Our standard ABS case meets basic safety requirements, but if you need a UL94 V-0 flame-retardant version, we can customize that for you with a slightly higher cost and longer lead time.
