I don't mind working with Inductors or surface mount components.Datasheet says 400mA charge current.
A couple of questions to potentially save time...
Do you mind working with inductors?
Do you mind working with surface mount components?

Try as I may I can not get onto this web pagetry looking here for other charger chips...

I tried it and it seems quite normal.Try as I may I can not get onto this web page
Thank you it may just be our internet connection or a site that sanctions ZimbabweI tried it and it seems quite normal.
Hi BertusHello Rodney,
I have printed the page to a PDF for you.

@RodneyBHi Bertus
I have it, Thank you for your help
Hi,They don't it's their protection circuit - please don't give advice on semi-dangerous stuff if you don't really understand it yourself.
The protection circuit should never be used as a charge limiter.Gee, i wonder how a protection circuit compares to a circuit that monitors battery condition in case anything goes wrong
Great, that really widens the range.I don't mind working with Inductors or surface mount components.
Hi,The protection circuit should never be used as a charge limiter.
A charger should be build safe and as if there wasn't any protection - then it's got a greater chance of being... safe
Relying on a protection circuit was never intended, it's the last resort - keep charging within limits that doesn't trigger the protection (some protection circuits are one-time protection, with an unuseable battery when the circuit opens).
The only supply in Africa that has they are US$20.00 each before freight and duty. Let me do some more researchGreat, that really widens the range.
The MAX1758 would work. It's got internal switching (i.e. no external MOSFETs needed), it comes in a 28 pin SSOP and only needs a single inductor to work.

Fetch the datasheet (from that page) and have a look at it.
I have no idea what it would cost you, but you might be able to get it as a free sample from Maxim
